FA-PLCA1×8SP , High Accuracy ABS Type 1x8 Fiber Optic PLC Splitter For FTTH With SC Connector
Low cost and high reliability are the basic requirements for
optical fiber splitter in FTTH engineering. Optical fiber splitter
can be divided into two types in terms of technology type: optical
fiber fused biconical taper and planar integrated optical
waveguide. Also named as FBT and PLC.
Optical fiber fused taper technology is the most mature technology
for 2 channels fiber splitter, at present optical splitter are
mainly all fiber optical splitter, its main features are: mature
technology, convenient connection with fiber, low insertion loss.
But with the increasing channel number of power, such as 1 x 8
optical fiber splitter or more, if we make it with FBT technology,
the fiber splitter will be with large volume, low efficiency, high
cost, and poor light uniformity. Furthermore, the characteristics
of the fiber optic splitter such as the pass band based on fused
biconical taper have great limitations.
PLC splitter is an integrated optical device based on planar
technology. Different from traditional FBT devices, it uses
semiconductor technology to integrate optical components of
different functions into a single chip. It is the basic technology
to realize the integration, large scale and miniaturization of
optoelectronic devices. Compared with fused biconical taper
technology, planar waveguide technology has the characteristics of
stable performance, low cost, and suitable for large-scale
production. So, in the future the FTTH System, FBT splitter or
coupler will no longer be used, and planar waveguide provides an
effective way for the production of access network optical devices
with high performance and low cost.
Generally, PLC chip including more than six kinds of materials,
they are: LiNbO3, waveguide is formed by diffusion of Ti ions in
LiNbO3 crystal and the waveguide structure is diffusion type; III -
V group semiconductor compounds ,waveguide is with InP as bottom
and a lower cladding layer, using InGaAsP as the core layer, use
InP or InP/air as upper cladding layer, the waveguide structure is
buried ridge or ridge; SOI (Silicon-on-Insulator), waveguide is
fabricated on SOI substrate, bottom, lower cladding layer, core
layer and cladding materials are Si, SiO2, Si and air; waveguide
structure ss the ridge shape and polymer, and silicon dioxide
(SiO2), glass ion exchange etc..
At present, fiber to the home (FTTH) network technology is mature,
but it can be rapid development and popularization or not, in
addition to the policy side, the most important and the most
critical point is to reduce the cost of all aspects of the network.
PLC optical splitter is one of the core devices in FTTx network,
and its low cost is an important technology development target.
From the technical, cost and the characteristics of the waveguide
materials given in the above, we can see that silica, polymer and
glass are the most suitable for making PLC chips.
