F-PLC  Compact LGX and Rack Mount Fiber Optic Cable Splitters , Combiners Couplers

The fiber optical splitter is a passive optical device that can split, or separate, an incident light beam into several light beams at a certain ratio

1x2, 1x4, 1x8, 1x16,1x32,1x64 1U rack mount type PLC splitter and

2x2, 2x4, 2x8, 2x16, 2x32, 2x64 1U rack mount type PLC splitters.


There are four types of fiber optic connectors are widely used for terminating single fibers. They are LC, SC, ST and FC connectors. LC connector has a 1.25mm ceramic ferrule which is only half the size of other connectors. It’s a snap-in connector usually used for high-density applications. SC connector uses a 2.5mm ceramic ferrule and also features a snap-in connection for quick cable patching. Different from other connectors, ST connector uses a bayonet twist-lock connection with 2.5mm ferrule. Moreover, FC is a screw type connector with 2.5mm ferrule but is becoming less popular than LC and SC connectors. This fiber optic splitter/fiber coupler provides Highest Quality Signal

Connector Polish Styles

When terminating the optic fiber with connector, you should also decide the polish type if the connector is not polished in advance. Generally, connector end face will be polished to minimize back reflection of light. Using the mated polish styles, light can propagate through connectors with lower fiber loss. There are four types of polish styles – flat, PC, UPC and APC polishes. Among them, UPC and APC types are more popular in the industry. The major difference between UPC and APC connectors is that the APC type is polished at an 8-degree angle while UPC has no angle, but they are both slightly curved for better core alignment. As for the color, UPC connector is usually blue and APC connector is green. Our Fiber Splitter provides Highest Quality Data transfer available.


Please note, each 1x N Optical Splitter Coupler has its own specific INSERTION LOSS  

It is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). The loss table below describes how it works with each box type of signal loss.

Question and Answers
F-PLC Compact LGX
I have some questions about some products
I need to know if you can advise me with the correct equipment
I need to transport an RF signal to two locations from a digital headend to inject the RF signal to an EDFA and distribute it with a Gpon network.
The first town is 15 km from the digital head and the second 25 km
I have planned to use your F-RF-1310-TX with a Fiber Optic Couplers and terminate at the distant site with an F-RF-RX-RM
what's the amount of splitter do you need?
if it is just 1x2 to go to two different towns; it would actually be better to just purchase to separate transmitters 32mW each
with distances like 15km and 25km it would also better to get an optical OTDR reading and measure the loss in the fiber lines first
the images of your product show distances of up to 40Km
how much power is attenuated when using a 1x8 splitter
This is based on regular loss of "perfect" conditions. If you are leasing the single-mode fiber, or if it has some loss, distortion, or bends then the optical reading with OTDR will be quite different. You should not depend on a product without knowing what the fiber itself is doing.
chart is at the bottom of the webpage for splitters
I get it
actually there are not only two sites, there are several but right now I need to transport the signal to two sites
so if you use a 32mW OTX plus a 1x8 coupler you have about a 5db budget to zero; our receiver will compensate maybe another 10 db; so maybe you will have 15 db to play with but with 25km of fiber that might not be enough.
So if you do have use an EDFA, it will be much more expensive but will be your only option. This is why the OTDR reading of the optical fiber is so important; the project can be accomplished on the cheaper side, or could become very expensive.
I think I should reach my "edfa" with 15db and then distribute with my GPON network
I think I should reach my "edfa" with 15db and then distribute with my GPON network
What would be the prices of the equipment that you suggest?
what is the distance you need to cover with the 1550mw OTx
we only make those in 8mW
25 km
Get an OTDR reading because 8mW on 1550 dissipates at .25db per km
