10BASE-T Collision Domain Cabling Topology

FacebookTwitterGoogle+LinkedInRedditTumblrShare

The overall topology of a 10BASE-T LAN is a tree of stars, as illustrated in Figure 1. The LAN in Figure 2 is constructed around four hubs and is a single collision domain. Each segment is at most 100 meters in length. The longest path throught the network passes through four hubs and crosses five sements.

An unbroken 100-meter run often is used to connect two hubs or to join a hub to a bridge. However, a horizontal cable run between a workstation and a hub normally is broken up into pieces, as Figure 3 shows. At the station end, a NIC is connected to a telecommunications outlet by a short cable called a patch cord. With the wiring closet at the other end, patch cords are used to complete the connection to a specific hub or switch.

A patch cord also is called a patch cable or a jumper cord. A patch cord that connects a user’s computer to an outlet often is called a work area cable. A Fiber Optic Patch Cord that connects a device to a hub or switch in a wiring closet often is called an equipment cable.

A typical breakdown is 90 meters for the long run between the telecommunications outlet and patch panels in the wiring closet and up to 10 meters for the patch cords used at each end. The patch cord connection between the station and the telecommunications outlet normally is limited to a length of 3 meters, at most.

Patch panels in a wiring closet enable the connections between end-user stations and hubs or switches to be rearranged by unplugging and replugging patch cables.

The patches shown at the top of Figure 3 are called interconnects. A station is attached to a new hub by unplugging the patch cable from the old hub and plugging it into the new hub. The patches shown in the lower part of Figure 4 are called cross-connects. Cables connected to the hubs do not need to be touched. An attachment is changed by plugging one end of a patch cord into a different socket. Cross-coonects are very convenient. However, they can degrade signals since they introduce more connector hardware into the cable patch.

The Basic Knowledge of Optical Fiber and Pigtail

How do fiber optic work?

Optical fiber communications composed of thin glass by the plastic protective overcoat layer. Glass essentially consists of two parts: the core diameter of 9 to 62.5μm, a low refractive index outer cladding diameter of 125μm glass material. Although according to the different materials
used, there are some other types of fiber, but is mentioned here that the most common types. Light in the core portion of the fiber to the “total internal reflection” mode transmission, but also refers to the light entering end of the fiber, the interface between the core and the cladding reflected back and forth, and then transmitted to the other end of the fiber. Core diameter of 62.5μm, outer cladding diameter of 125μm fiber called 62.5/125μm fiber.

What is the difference between multimode and single-mode fiber?

Multimode Fiber Optic Patch Cables

Almost all of the Multimode Fiber Optic Patch Cables dimensions are 50/125μm or 62.5/125μm, and the bandwidth (the amount of information transmission fiber) is usually 200MHz to 2GHz. Multimode optical transceiver via multimode fiber can be up to 5 km of transmission. In the light emitting diode or a laser light source.

Single Mode Fiber Cable

The size of Single Mode Fiber Cable 9-10/125μm, and compared with a multimode optical fiber, it has unlimited bandwidth and low loss characteristics. The single mode optical transceiver used for long-distance transmission, and sometimes up to 150-200 km. Using a narrow spectral line LD or LED as a light source.

Single mode fiber is cheap, but compared to multi mode fiber device, it is more expensive. Single-mode devices typically can run on single mode fiber, but also be run on a multi mode fiber, and multimode device only runs on multimode fiber.

How is the loss with using of the Fiber Optic Patch Cables?

It depends on the the wavelength of the transmitted light and the kind of optical fiber

When 850nm wavelengths for multimode fiber: 3.0 dB / km
When 1310nm wavelength for multimode fiber: 1.0 dB / km
When 1310nm wavelength for single mode fiber: 0.4 dB / km
When 1550nm wavelength for single mode fiber: 0.1 dB / km

Fiber Optic Pigtails

Fiber Optic Pigtails ony has one end connector, and the other end is an optical fiber core breakage, by fusion connected with other core cable, often appear in the fiber optic terminal box for connecting cable and fiber optic transceivers.

Fiber optic pigtails devide into multimode and singlemode fiber pigtails. Multimode fiber pigtail is orange and wavelength of 850nm, the transmission distance of 500m, for short-range connectivity. Single mode fiber pigtail is yellow, there are two wavelengths, 1310nm and 1550nm, transmission distance of 10km and 40km.

Fiber optic pigtail connector was devided into single mode and multimode by the mode of fiber optic cable; By overall structure can be divided into FC, SC, ST, MU, LC, F25, etc. By the end structures can be devided into PC、UPC、APC.

Knowledge about Fiber Optic Pigtails

Much about the tech jargon, some people don’t know its meaning. Such as fiber optic pigtails, fiber pigtail is a piece of fiber optic cable with only one fiber optic connector on one side of the cable, there are single mode and multimode fiber optic pigtails, which can be with various types of fiber optic terminations such as SC, FC, ST, LC, MU, MT-RJ, MTP, MPO, etc. the fiber optic pigtail with connector side is used to link the equipment, while the other side of the pigtail is melted together with the fiber cable, by melting together the fiber glasses, it can reach a minimum insertion loss. Fiber optic pigtails are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets. Common types of fiber optic pigtails are usually with 0.9mm fiber cable diameter, and usually installed inside ODF unit. Most commonly used types are SC fiber optic pigtail, ST fiber optic pigtail,FC fiber optic pigail, LC fiber optic pigtail ,MT-RJ fiber optic pigtail,SC/APC fiber optic pigtail, FC/APC fiber optic pigtail and E2000 fiber optic pigtail. They are single mode types and multimode types.

A fiber pigtail is really a single, short, usually unbuffered, optical fiber which has an optical connector pre-installed on one end along with a period of exposed fiber in the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber within the trunk “breaks out” the multi-fiber cable into its component fibers for connection to the end equipment.Fiber pigtails can have female or male connectors. Female connectors might be mounted in a patch panel, often in pairs although single-fiber solutions exist, to allow them to be connected to endpoints or other fiber runs with patch fibers. Alternatively they can have male connectors and plug directly into an optical transceiver.As the fibers must have connectors fitted before they can affix to other equipment. Fiber pigtails may be one of the common solutions for fiber cable termination, the inclusion of connectors to every optical fiber in a cable.

According to the ITU-T (International Telecommunication Union Telecommunication) standardization organization, fiber optic pigtails are categorized into Fiber pigtail that conforms to G.652 and G.653 fiber splicing technology standard. Fiber optic splicing technology is primarily to use a fiber splicing machine to fuse splice the fiber with fiber or the fiber with fiber pigtails. In this process, the bare fibers of the fiber optic cables are fuse spliced with the fiber pigtails to become a whole. With the fiber optic connector at one end of the fiber pigtails, they are connected to fiber optic transceivers, the optical fibers connected with the twisted pairs, and then connect with the information outlets. Main tools used in the fiber splicing technology include fiber termination box, fiber optic converter, fiber optic transceiver, fiber pigtail, optical fiber coupler, fiber stripper, and fiber optic cleaver, etc. Currently fiber optic pigtail with SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors are available in the market.

Select The Fiber Optic Patch Cable Types

Fiber patch cables would be the backbone of the fiber optics industry. Fiber Patch (Fiber Patch Cable or Fiber Jumper) is strands of optically pure glass as thin as real hair. Fiber patch cable is definitely an fiber cable which has fiber connectors placed on one ends. General utilization of these cable assemblies includes the interconnection of fiber cable systems and optics-to-electronic equipment. Another information on patch cable, if the fiber connectors are affixed to just one end of the cable, it’s called the fiber optic pigtails, in the event the fiber connectors are affixed to both ends, it is known as a fiber jumper or fiber patchcord.

Fiber Patch Cables Types

Given the high diversity you could face when trying to select a fiber patch, professionals happen to be classifying them to simply communication and organization. There are lots of ways to classify fiber patch cables:

Fiber cable type based classification:

Simplex and Duplex are the two main types of fiber cable. Simplex fiber patch cables feature one fiber then one connector on each side. A Duplex fiber optic cable has two fibers and a couple connectors on both ends.

Termination connector type based classification:

As with any connection system, termination types and compatibility are crucial.

There are generally two methods to terminate a fiber cable:

Indentical connector type for both ends of the cable; two different kinds (Hybrid) of connectors on each side with the cable.

Supported optical fiber modes based classification:

There are 3 different modes available when operating fiber patchcord: singlemode, multimode, and 10 Gigabit multimode.

Size from the fiber cable based classification:

Manufacturers make Fiber Optic Patch cord in the following sizes: 250 um, 900 um, 1.6 mm, 2.0 and 3.0 mm fiber optic cable.

Information About Cable Components

Pick up any cabling catalog, and you may locate a variety of components and associated buzzwords that you never dreamed of. Including patch panel, wall plate, plenum, modular jacks, raceways, fiber optic pigtails and patch cords are only a few. Exactly what do all of them mean, and just how are these elements used to create a structured cabling system?

In this blog, we’ll provide some information about the structured cabling system so that you won’t feel so confused next time you select up a cabling catalog or assist professional cabling installers. Today, we mainly explain the cable components relevant information. If you wish to find out about components, pls visit FiberStore Tutorial, we provide some detail information regarding the fiber optic components.

We’ll describe the constituents involved with transmitting data from the work area towards the telecommunications room or enclosure. These major cable components are horizontal cable, backbone cable, and patch cords used in cross-connections and then for connecting to network devices.

Horizontal and Backbone Cables

The terms horizontal cable and backbone (sometimes called vertical or riser) cable do not have anything regarding the cable’s physical orientation toward the horizon. Horizontal cables run between a cross-connect panel in a telecommunications room and a telecommunications outlet located near the work area. Backbone cables run between telecommunications rooms, and enclosures,as well as the main cross-connect point of a building (usually found in the equipment room). The photo illustrates the standard components seen in a structured cabling environment, like the horizontal cable, backbone cable, telecommunication outlets, and patch cords.

Fiber Patch cord

Fiber patchcord can be used in patch panels to supply the link between field-terminated horizontal cables and network connectivity devices (for example switches and hubs) and connections between the telecommunications outlets and network devices (including computers, printers, as well as other Ethernet-based devices). They are the part of the network wiring you could see. As the saying goes, a sequence is merely as strong since it’s weakest link. Due to their exposed position in structured cable infrastructures, patch cords are nearly always the weakest link.

Whereas horizontal UTP cables contain solid conductors, patch cords are created with stranded conductors because they’re more flexible. The flexibility allows them to withstand the abuse of frequent flexing and reconnecting. Although you could make your own field-terminated patch cords, we strongly suggest against it.

The manufacture of patch cords is quite exacting, and even under controlled factory conditions it is difficult to attain and guarantee consistent transmission performance. The first challenge lies inside modular plugs themselves. The parallel alignment from the contact blades forms a capacitive plate, which gets to be a source of signal coupling or crosstalk. Further, the untwisting and splitting of the pairs as a result of the termination process raises the cable’s susceptibility to crosstalk interference. In the event that weren’t enough, the mechanical crimping method that secures the plug towards the cable may potentially disturb the cable’s normal geometry by crushing the conductor pairs. This is another supply of crosstalk interference along with a source of attenuation.

Tip:Patch cords which were factory terminated and tested are required to achieve consistent transmission performance. At first, patch cords seems to be a no-brainer, nevertheless they could possibly function as the most important element of accurately specify. When specifying patch cords, it’s also possible to require your patch cords be tested to make sure that they fulfill the proper transmission-performance standards for category.For more information about fiber optic patch cable types or want to buy the patch cable, pls contact this email: sales@fs.com.

Common Kinds of Hybrid Fiber Patch Cord

Recently, it is now apparent that fiber optic cable is steadily replacing copper wire as an appropriate way of communication signal transmission. They span long distances between local telephone systems in addition to supplying the backbone for a lot of network systems. Other system users include cable tv services, university campuses, buildings, industrial plants, and electric utility companies. A fiber-optic method is just like the copper wire system that fiber-optics is replacing. For example, fiber patch cord is one of the most often used components inside the fiber optic network.

Fiber patch cable (also referred to as fiber jumper cable or fiber patchcord) is used for connecting one optical device to a different, sometimes with two different connection types. You can find 4 connector types: LC, SC, ST and MTRJ which may be arranged in a configuration to match your connection needs. Including SC fiber cable (SC LC fiber patch cord), LC fiber patch cable (LC to ST fiber cable), ST fiber patch cable (ST to LC fiber patch cable, ST to SC fiber patch cable), ect.

Connector Types:

1. Same connector type fiber patch cable: This fiber optic patch cable gets the same type of connector on both ends, for example ST, SC, LC, FC, MTRJ, E2000, MU, etc.

2. Hybrid fiber optic patch cables: This fiber optic patch cable has different connectors on each end. One end could be SC and the opposite end could be LC, ST, FC, MTRJ, E2000, MU, etc.

We must learn more details about the fiber optic patch cable types, for instance, the hybrid fiber optic patch cables, LC to ST fiber cable is terminated with LC fiber optic connectors on a single end and ST fiber optic connectors however. Called Lucent Connectors, Little Connectors or Local Connectors, these snap-in connectors are typically useful for high density connections and are compatible with plug-and-play devices for example SFP modules and XFP transceivers. Straight Tip (“ST”) connectors use a bayonet-style coupling type, enabling a simple twist-on and twist-off installation. Do not let many of these connectors of different shapes and sizes fool you. Different devices opt for different connector types.

FiberStore provides different types of fiber patch cords including common single-mode 9/125, OM1 62.5/125, OM2 50/125, 10G OM3/OM4 patch cables, armored patch cable, fiber optic pigtails, multi core patch cables, MPO/MTP fiber and other special patch cables.

Instead, give us a call or even an email, we are able to assist you in finding what you want as well as make it custom.

Common Types of Fiber Patch Cables

In the event you working in telecommunications industry, acquiring thorough information about fiber optic patch cables is essential. Fiber patch are used for linking the apparatus and components in the fiber optic network ,they are with various types of fiber optic connector types. The fiber optic patch cord types are classfied by the fiber optic connector types. For example,we name LC fiber patch cable since this cable is to use LC fiber optic connector. You will find PC,UPC,APC type fiber patch cord, they’re different as a result of polish of fiber connectors. Fiber optic patch cables are available with ST SC LC FC connectors.Fiber optic patch cables may be split into different types according to fiber cable mode, cable structure, connector types, connector polishing types and cable sizes. However nowadays I would like to based on fiber connectors to introduces the normal kinds of fiber patch cable.

Common Forms of Fiber Patch Cable:

SC Fiber Optic Patch Cord
SC fiber optic patch cable is one of the earliest type and something of the very most commonly used fiber optic cable, it is simple to use and value saving, SC fiber cable is widely uesed in fiber optic networks. SC fiber patch cable is by using zirconia sleeve and plastic housing. Oahu is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

The SC fiber optic patch cord was invented by the Japanese company NTT. It really is probably the most popular fiber optic patch cords. SC fiber optic patch cord features low priced , simplicity along with good durability, SC fiber optic patch cords is with a locking tab about the cable termination, it’s a push and pull type fiber optic connector.

FC Fiber Optic Patch Cord
FC fiber optic patch cords are with FC fiber optic connectors ,the industry screw type connection. FC fiber optic patch cords were quite definitely popular previously ,but people have a tendency to use LC and SC to switch FC more and more. It’s the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

The FC fiber optic patch cable comes in both singlemode and multimode versions, and it is fully intermateable with NTT-FC products. Both smf and mmf versions FC fiber optic patch cord have a zirconia ceramic ferrule with pre-polished PC profile and convex spherical end.

ST Fiber Optic Patch Cord
ST fiber cable connector features a bayonet-style housing along with a long spring-loaded ferrule support the fiber. They are available in both multimode or singlemode versions. Horizontally mounted simplex and duplex adapters are available with plastic or metal housing. It is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

ST fiber optic patch cords standard was created by AT&T. this sort of cable is with straight tip type terminations. there is only simplex ST fiber optic patch cords with no duplex ones.These days ST fiber optic connectors are generally having a metal housing ,nevertheless, there are plastic housing ST fiber connectors, more and more people often use metal housing ST. ST APC fiber optic patch cord are also available.

LC Fiber Optic Patch Cord
The LC fiber optic patch cable is by using a little form factor (SFF) connector and is perfect for high density applications.LC fiber optic patch cord connector includes a zirconia ceramic ferrule measuring 1.25mm O.D. having a PC or APC endface, and provides optimum insertion and return loss. It is the standard fiber optic cable assemblies, with simplex, duplex patch cords and standard pigtails.

LC will be the short kind of Lucent Connector, LC fiber patch cord connector can be a push and latch structure, with plastic housing and accurate 1.25mm ceramic ferrule. LC type is a well-liked type of small form fiber optic patch cord which decrease the space and it’s also popular for densely installation.
