6 Steps Help to Choose Right Fiber Patch Cord Types


There are many fiber patch cord types, such as OM1, OM2, OM3, OM4 multimode fiber and OS2 single mode fiber types. Both ends of the cable are terminated with a high performance hybrid or single type connector comprising of a SC, ST, FC, LC, MTRJ, E2000 connector in simplex and duplex. These are typically not ruggedized, depending on the application, making them suitable for internal use. How to choose right fiber patch cord types for your network? Just follow these 6 steps.

Step 1: Choose the Right Connector Type (LC/SC/ST/FC/MPO/MTP)

Different fiber patch cord typesOn both ends of the fiber optic patch cord are terminated with a fiber optic connector (LC/SC/ST/FC/MPO/MTP). Different connector is used to plug into different device. If ports in the both ends devices are the same, we can use such as LC-LC/SC-SC/MPO-MPO patch cables. If you want to connect different ports type devices, LC-SC/LC-ST/LC-FC patch cables may suit you.

Step 2: Choose Single-mode or Multimode Cable Type?
Single-mode fiber patch cord uses 9/125um glass fiber, Multimode fiber patch cord uses 50/125um or 62.5/125um glass fiber. Single-mode fiber optic patch cord is used in long distance data transmission. multimode fiber optic patch cord is use in short distance transmission. Typical single-mode fiber optic patch cord used yellow fiber cable and multi mode fiber optic patch cord used orange or aqua fiber cable.

Step 3: Fiber Patch Cord Types – Choose Simplex or Duplex?
Simplex means this fiber patch cable is with one cord, at each end is only one fiber connector, which is used for Bidirectional (BIDI) fiber optic transceivers. Duplex can be regarded as two fiber patch cable put side by side, which is used for common transceivers.

Step 4: Choose the Right Cable Length (1m/5m/10m/20m/30m/50m)
Fiber optic patch cables are made in different lengths, usually from 0.5m to 50m. You should choose an appropriate cable length according to the distance between the devices you want to connect.

Step 5: Choose the Right Connector Polish Type (UPC/APC)
Since the loss of the APC connector is lower than UPC connectors, usually, the optical performance of APC connectors is better than UPC connectors. In the current market, the APC connectors are widely used in applications such as FTTx, passive optical network (PON) and wavelength-division multiplexing (WDM) that are more sensitive to return loss. But APC connector is usually expensive than UPC connector, so you should weigh the pros and cons. With those applications that call for high precision optical fiber signaling, APC should be the first consideration, but less sensitive digital systems will perform equally well using UPC. Usually, connector color of APC patch cable is green, and of UPC patch cable is blue.

Step6: Choose the Right Cable Jacket Type (PVC/LSZH/OFNP/Armored)
Usually, there are three cable jacket types: Polyvinyl Chloride (PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber Nonconductive Plenum (OFNP). You can see there features in figure below and choose the right one for your network.

Besides the three cables mentioned above, there is another common cable—Armored Cable. The double tubing and steel sleeve construction make these patch cables completely light tight, even when bent. These cables can withstand high crushing pressures, making them suitable for running along floors and other areas where they may be stepped on. The tubing also provides excellent cutting resistance, abrasion resistance, and high tensile strength.

Fiber Optic Cables Are The First Option For Data Transmission


Fiber Optical Cable has brought a revolution to the data transmission system. As the earlier Electrical Wire System was difficult to manage and was sometimes also hazardous to life. With the emergence of Fiber Optical Cable, data transmission is no more an irksome job. It is now simplified, providing much more convenient than ever imagined.

Following Are The Reasons For Choosing Optical Cables For Network Cabling:

Safe To Use: Fiber Cable is far better than copper cable from the safety point of view. Copper and Aluminum Wire are good conductors of electricity and carry electric current. But when their outer insulated coating gets damaged, one can experience electric shock that can be dangerous to life. In this regard, Fiber Cables are safer to use because they do not transmit current but rather light waves.

Withstand Rough Conditions: Fiber Cable is capable of resisting tough conditions that co-axial or any other such cable cannot do. The reason is that other cables are usually made up of one or the other metal and are prone to corrosion, while Fiber Cable is covered with protective plastic coating with glass inside and transmits light impulses in spite of electric current, which make it resistant towards corrosion.

Long Distance Data Transmission: There cannot be any comparison in terms of data carrying capacity of Fiber Optical Cable and Copper Cable. Fiber Cable can transmit signals 50 times longer than Copper Cable.

Moreover, signal loss rate of Fiber Optical Wire is also very less, and thus does not need any kind of reminder in transmitting the signals at same pace. Fiber Cable has higher bandwidth that is amount of data communication resources available or consumed – this is the reason how Fiber Cable can transmit data at longer distances.

Easy Installation: Ethernet Cable is long and thin with intact cables inside. It is also light in weight which makes its installation at almost every place easier as compared to other wires.

No Electrical Interference: Fiber Optical Cable neither carries electric current nor need earthing. Therefore, it does not get affected by the electrical interferences. Fiber Cable is immune to moisture and lighting, which makes it ideal to be fitted inside the soil or an area where there is high Electromagnetic Interference (EMI).

Durable and Long Lasting: Fiber Optical Cable is durable and lasts longer than any other cable such as Co-Axial Cable, Copper Cable, etc. It is perfect for network cabling.

Data Security: Extra security can be provided with Fiber Optical Cable as it can be tapped easily and data transmitted through it remains secure, while in case of the Copper Cable there is no surety of data security and any loss of data cannot be obtained back.

There are various types of optical fiber cables available on the market, including 250um Bare Fiber, 900um Tight Buffer Fiber, Large Core Glass Fiber, Simplex Fiber Optic Cables, Duplex Multimode Fiber Optic Cable, OM4 OM3 10G Fiber Cable, Indoor Distribution Cable, Indoor & Outdoor Cable, Outdoor Loose Tube Cable, Fiber Breakout Cable, Ribbon Fiber Cable, LSZH Fiber Optic Cable, Armored Fiber Optic Cable, FTTH Fiber Optic Cable, Figure 8 Aerial Cable, Plastic Optical Fiber, Polarization Maintaining Fibers & Special Fiber, etc. They are used for different applications, one must do a thorough research before buying fiber cables for network cabling.

Overview Simplex and duplex Fiber Optic Cable


Simplex and duplex are with various cable structure types; they have some from single mode and multi mode which are related to fiber optic glass types.From FiberStore,we provide some bulk fiber optic cables types in our store.Such as Simplex Fiber Optic Cable and Duplex Fiber Optic Cable,we also have other types cables in it.Customers have the flexibility to choose a cable plant to best fit their needs.We are the professional fiber optic cables supplier ,and provide high quality service for you.

Simplex Fiber Optic Cable:

Simplex Fiber Optic Cables will be used when a signal only needs to go in one direction. They are designed for production termination where consistency and uniformity are vital for fast and efficient operation.

Simplex Fiber Optic Cable consists of a single fiber,tight-buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use, and is used mostly for patch cord and backplane applications. Analog to digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors (for sports applications) are all great uses of Simplex fiber optic cable. This form of fiber cable can be cheaper than Duplex cables, because less material is involved. Simplex Fiber Cable is a single fiber available in single mode, multimode, or polarization maintaining, and they can meet the strength and flexibility required for today’s fiber interconnect applications. We also supply Riser, Plenum rated constructions and LSZH jacket.

Duplex Fiber Optic Cable:

Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Either single mode or multimode,they are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable.

Duplex fibers types:

  • Half-duplex: Data may only be transmitted in one direction at a time.
  • Full-duplex: Data is transferred in two directions simultaneously.

Other duplex infomation:A duplex communication system is a point-to-point system composed of two connected parties or devices that can communicate with one another in both directions, simultaneously. Now, Duplex systems are employed in many communications networks, either to allow for a communication “two-way street” between two connected parties or to provide a “reverse path” for the monitoring and remote adjustment of equipment in the field.
