How does a Fiber Optic PLC Splitter work

- Apr 10, 2018-

G  Why Do We Need PLC Splitter?

PLC(Planar Lightwave Circuit) refer to Planar Lightwave Circuit, PLC splitters are used to distribute or combine optical signal. It is based on planar lightwave circuit technology and provides a low cost light distribution solution with small form factor and high reliability.

A How Does a PLC Splitter Work?

PLC Splitters are installed in each optical network between the PON Optical Line Terminal (OLT) and the Optical Network Terminals (ONTs) that the OLT serves. Networks implementing BPON, GPON, EPON, 10G EPON, and 10G GPON technologies all use these simple optical splitters. In place of an optical splitter, a WDM PON network will use an Arrayed WaveGuide (AWG).

B What Is one of the most Important function should really a PLC Splitter Have?

Passive Optical Network (PON) splitters play an important role in Fiber to the Home (FTTH) networks by allowing a single PON network interface to be shared among many subscribers. Splitters contain no electronics and use no power. They are the network elements that put the passive in Passive Optical Network and are available in a variety of split ratios, including 1:8, 1:16, and 1:32. 

B Different types of PLC Splitter

Rack PLC Fiber optic splitter

19 standard rack PLC Splitter is a key component in FTTH and is responsible to distribute the signal from CO to numbers of premises. The highly stable splitter performs superbly across temperature and wavelength providing low insertion loss, low input polarization sensitivity, excellent uniformity, and low return loss in configuration of 1×4, 1×8, 1×16, 1×32 and 1×64 port.

Mini Plug-in PLC Splitter

It Looks like LGX box PLC splitter but usually uses ABS material box. Can be used in outdoor fiber distribution box in FTTX.

LGX Box PLC Splitter

The whole PLC splitter is housed in a metal box and the fiber optic adapters for both input and output fibers are on its front panel. It can be used to stand alone or be installed in the standard rack unit/enclosure.

ABS PLC Splitter

ABS PLC Splitter uses ABS plastic box to hold the PLC splitter chip. Input fiber and output fibers are arranged on the same plate of the ABS box. It can be installed in standard 19” rack unit/enclosure.

Fan-out PLC Splitter

It adds a length of ribbon fiber terminated with fan-out kit behind the PLC split chip. Generally uses 0.9mm buffer fiber.

Blockless PLC Splitter

Resembles bare fiber PLC splitter, but has fiber optic connectors. It uses stainless tube package for the PLC splitter chip.

Bare Fiber PLC Splitter

Bare Fiber PLC Splitter is the simplest PLC splitter type. All ends are bare fibers (0.9/2.0/3.0µm). It can be spliced freely according to the applications which require the least space during cabling.
