Fiber Optic Solution

In FTTx and PON architectures, fiber optic splitter is an important component to share the optic network with multiple users. The basic principle of fiber optic splitter is to split one optic light beam into several parts at a certain ratio. According to different manufacture technologies, fiber optic splitters can be divided into PLC splitter and FBT splitter. You may wonder the differences of the two splitter types when making a choice between them. This article aims at helping you to understand their distinctions and make better decisions. Basics of PLC & FBT Splitters What Is  PLC Splitter ? PLC refers to planar lightwave circuit. As a micro-optical device, PLC splitter uses an optical chip to split the input signal into various outputs. At the edge of the chip, there is a light circuit in ribbon form mounted on a carrier and fibers. PLC splitter typically adopts silica glass as the material of lightwave circuit and accepts different types of polished finishes. The s...

As fiber optic link becomes more and more acceptable by average consumers, Passive Optical Network (PON) systems are more widely deployed in common homes. Fiber optic splitter is an indispensable passive optical device in PON systems. Optical splitters can be divided into Fused Biconical Taper (FBT) splitter and Planar Lightwave Circuit (PLC) splitter.  PLC splitte r  is newer than FBT splitter and is also the focus of this post. What Is PLC Splitter? PLC splitter, also called Planar Waveguide Circuit splitter, is used to divide one or two light beams to multiple light beams uniformly or combine multiple light beams to one or two light beams. It is a passive optical device with many input and output terminals, especially applicable to PON (EPON, GPON, BPON, FTTX, etc.) to connect the MDF (main distribution frame) and the terminal equipment and to branch the optical signal. Fiber PLC splitter provides a low cost light distribution solution with high stability and reliabili...
