One Small Problem When We Choose the Fiber Patch Cable

FacebookTwitterGoogle+LinkedInRedditTumblrShare

There is a common phenomenon that people are always able to distinguish different types of interfaces easily after corresponding to the given pictures, but when we choose the fiber patch cable, such as the polishing type also confused them, it shows UPC or APC, also confused us, recently I finally understand it and share my ideas with you.

First we can look from the definition, the above are acronyms for the following:

    • UPC – Ultra Physical Contact
    • APC – Angled Physical Contact

Only from the words we can have a simple understanding of them, in order to have a deeper understanding, there i named a few examples for you. Usually when we hear about the description like “fiber patch lc apc lc upc”, “e2000 fc apc”, “sc apc to sc upc single mode 9 125 simplex fiber optic patch cord cable”, what do this words apc upc mean? Then we will give you explanations. In Fiberstore, We use different color to distinguish them, the blue is UPC connector and the green is APC connector, shown as the figure.

In fact, it stands for the polish style of fiber optic core and connect the copper connector of copper cable as medium, and we need to know that the connections between the fiber optic connector and the ceramic core. Different fiber optic connector ring’s size, length and polished style is different, different polish of the fiber optic connector rings result in different performance, mainly on the back reflection. Generally, UPC is 50dB or higher and APC is 60dB or higher. All insertion loss of that they should be less than 0.3dB and the lower insertion loss is, the better performance they have, it is the reason why UPC connector is more widespread than APC. At the same time, there is a point we need to pay attention to, we all know that fiber optic cables can be divided into single mode and multimode fiber cables, but single mode fiber optic cables can be with UPC or APC polished connectors, while multimode fibers are not made with APC connectors. When we talk about the insertion loss, fiber optic attenuators have to be mentioned, it also has the diffent db to choose, as for the more knowledge about it, please always pay close attention to.

Fiberstore, you know, it offers kinds of fiber cables to choose, the different connector series all available for UPC/APC version, and we can also provide SM, MM, OM3 cables, simplex and duplex option, 0.9mm, 2.0 mm, 3.0mm cable diameter for choose, as for the fiber length, it can be customized according to your requirements.

MPO/MTP Fiber Interconnection Products FAQs

The increasing demand on today’s higher fiber counts has exploded the development of multi-fiber technology. FiberStore is one of the main manufacturing of MPO/MTP fiber patch cable and cassettes, and many other MPO/MTP fiber interconnection products, which engineers unique MTP solutions using 12, 24, 48 and even 72 fiber MTP ferrules.

What is an MTP Trunk Cable?
An MTP trunk cable provides 12 to 144 fibre connectivity, by using 12-fibre push/pull optical connectors, it minimized errors and reduced spaces. The MTP trunk cable allows for lower bend radii and smaller slack loops. It enables up to 6x the cable tray capacity over traditional bulkier cabling solutions, saving up to 65 percent space. MPO trunk cable features round furcation legs that provide easy routing and improved storage. With the small profile furcation plug, it allows stress free cable mounting, leaves no legs outside the housing and shipped with strain-relief mounting cradles.

What is MTP Extender/MTP Extension Trunk?
The MTP extension Trunk extend subsets of links from zone distribution into equipment zones, which feature pinned (male) MTP connector on one end and non-pinned (female) MTP connectors on the other. It pinned MTP side mates with trunks via MTP connector panels, while not pinned MTP side plugs into modules or harnesses.

What is MTP couplers?
MTP couplers are simple plastic rectangles that hold two MTP connectors together. One cable going into an MTP coupler needs to have a male connector. The other cable must have a female connector. MTP couplers can be either key-up to key-up, or key-up to key-down. MTP cable has a clip on the top of the connector. On a key-up to key-up coupler, the clips are pointed in the same direction on both of the cables. On a key-up to key-down coupler. On a key-up to key-down coupler, the clips are on opposite sides. This also affects the polarity of the signal. Key-up to key-up couplers invert polarity. Key-up to key-down couplers retain the original polarity. This was initially counter-intuitive to me. It made sense once I thought about it though.

What is MTP harness?
An MTP harness breaks out 12 fiber MTP terminations into LC duplex connectors. It connects to trunks through a pinned MTP connector plug into dual fiber electronics ports with LC uniboot duplex connectors. It is occupying less space than 6 duplex jumpers improve airflow for cooling efficiency. By easing handling of cable connections on high-fibre count SAN directors and switch blades, it enables higher density in equipment patch panels. MTP harnesses are available in two lengths: short harness legs for minimal cable slack and long harness legs for mounting flexibility within a cabinet.

How To Install and Test the Fiber Optic Cables

In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don’t froget, when you install the fiber optics, you must testing your fiber optic system. Optical-fiber testing is one of the final and most important procedures in installing optical networks.

How to install the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables can be installed in raceways, cable trays,placed in hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. The installation process will depend on the nature of the installation and the type of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Follow the cable manufacturer’s recommendations. Fiber optic cable is often custom-designed for the installation and the manufacturer may have specific instructions on its installation.
b) Check the cable length to make sure the cable being pulled is long enough for the run to prevent having to splice fiber and provide special protection for the splices.
c) Try to complete the installation in one pull. Prior to any installation, assess the route carefully to determine the methods of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in all fiber optic cables for verification of proper installation. Perform the following tests:
a) Continuity testing to determine that the fiber routing and/or polarization is correct and documentation is proper.
b) End-to-end insertion loss using an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be less than the calculated maximum loss for the cable based on appropriate standards or customer specifications.
c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be used to determine cable loss.
d) If the design documentation does not include cable plant length, and this is not recorded during installation, test the length of the fiber using the length feature available on an OTDR, or some OLTSs.
e) If testing shows variances from expected losses troubleshoot the problems and correct them.

Basic Technology About Fiber Optic Cable

From data and voice to security and videoconferencing, many of today’s IT infrastructure services rely on fiber optics to transmit information faster, farther, and in greater amounts than ever before. So fiber optics are more and more popularity in our internet. This post will try to answer some of the basic questions about fiber optic cable.

What is fiber optic cable?
A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. These cables are designed for long distance and very high bandwidth (gigabit speed) network communications. If you want to know more info about fiber optic cable specifications, you can visit the FiberStore “Fiber Optic Cable Tutorial” in our tutorial.

There are two types of optical fiber cables, Single-mode VS Multimode?
Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode fiber-typically 5 to 10 microns. Only a single lightwave can be transmitted at a given time. The small core and single lightwave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

Multimode fiber gives you high bandwidth at high speeds over long distances. Lightwave are dispersed into numerous paths, or modes, as they travel through the cable’s core. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet (914.4 ml), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission. For example, you can try to compare the single mode duplex fiber vs multimode duplex fiber optic cable, and well know their different.

Relationship between fiber optic cable and fiber patch cord:
A fiber patch cord is a fiber optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box. This is known as “interconnect-style cabling”.

What types of connectors should be used?
There are a number of connector styles on the market including LC, FC, MT-RJ, ST and SC. There are also MT/MTP style connectors that will accommodate up to 12 strands of fiber and take up far less space than other connectors. This connector is intended for use with indoor loose tube no-gel cable constructions. However, the most popular connectors are SC, which push in then click when seated, and ST, also known as bayonet style, that are pushed in and twisted to lock. That should be a consideration when making product selections.

What kind of jacket rating and type do you require?
Fiber cable jackets come in many styles. As an example, fiber can be Indoor only, Outdoor only, Indoor/Outdoor, Tactical and it can also have Plenum or Riser ratings.

Jacket color is relatively standardized.
a) Multimode = Orange
b) 50/125um 10G = Aqua
c) Single Mode = Yellow
d) Indoor/Outdoor or Outdoor = Black
e) Custom jacket colors are also available for indoor fiber cables
