What is a PLC Splitter?

A Planar Lightwave Circuit (PLC) splitter is a passive optical splitter based on optical
semiconductor technology. A PLC splitter’s manufacturing process is similar to those of
semiconductors. A typical PLC splitter consists of a PLC chip along with input and output arrays,
the number of which depends on the split ratio.

PLC splitters, are used to evenly divide one or two optical signals into multiple optical signals.
PLC splitters are passive optical devices that are widely used in Passive Optical Networks
(PON) by connecting to the Main Distribution Frame (MDF). FTTH and FTTx Networks such as
BPON, GPON, EPON, and xG EPON all utilize PLC Splitters in their design.

As demand for higher bandwidth continues to grow, telecommunications companies rely on
Passive Optical Networks (PON) and Neptec’s reliable PLC splitters to provide fiber optic links
to an increasing number of users. PLC splitters allow a single PON network interface to be
utilized by multiple users, maximizing a fiber network’s user capacity in increasing ROI.
Neptec offers PLC splitters with 1×2 to 64 or 2×2 to 64 split ratios. In addition Neptec offers a
variety of form factors and packaging to fit PLC splitters into various environments and
applications. If you have any questions or would like to learn more about Neptec’s PLC splitters,
please contact us and we would be glad to help.
