PLC Splitter Vs FBT Coupler

FBT Coupler and PLC splitter Tech

PLC Splitter

Planar Lightwave Circuit (PLC) splitter, PLC splitters are used to distribute or combine optical signals. It is based on planar lightwave circuit technology and provides a low cost light distribution solution with small form factor and high reliability. Planar lightwave circuit (PLC) splitter is a type of optical power management device that is fabricated using silica optical waveguide technology to distribute optical signals from Central Office (CO) to multiple premise locations.

FBT Coupler

Fused biconical taper,this is traditional technology to weld several fiber together from side of the fiber.

Comparison between FBT and PLC.

PLC splitter

SpliSplit Ratio (Max): 1*64 splits
Eveness: Can split light evenly
Size: Compact size

FBT coupler

Split Ratio: 1*8 splits
Eveness: Eveness is not very precise
Size: Big size for multi splits

Optical Performance

We use fiber optic splitter to distribute or combine optical signals in many applications,

we have one question: Shall I use PLC or Fused Splitter ? When we do comparison, we need to do comparison for devices of the same split-ratio.
