Description
Introduction
Planar Lightwave Circuit
Splitter (PLC Splitters) is a kind of power splitter based on the
integrated quartz baseplate with small size, wide operating
wavelength range, high
reliability,
andgooduniformity so on,especially suitable for passive optical network (EPON,BPON,GPON,etc.) to
connect the central office and terminal equipment
forachievingthebranchingoftheoptical
signal.So far there are two
types of PLC 1×N and 2×N Splitter .PLC 1×N and 2×N Splitter divide
uniformly optical signals from one or two inputs to multiple
outputs, and splitter can be operated in reverse direction to
combine multiple signals into fiber or two fibers.
Production
technology
The PLC splitter
adopts semiconductor process (photolithography, etching, and
developing technology so on) production. Waveguide array is located
on the upper surface of the chip, and the shunt function is
integrated on the chip, which is implemented on a chip 1, 1
branching. Then, couple the input end and the output end’s the
multi-channel fiber array and packing separately at both ends of
chip.
Compared with FBT
SPLITTER,PLC SPLITTER has the following few
advantages:①Loss is not insensitive to light
wavelength, so it can meet transmission needs of different
wavelengths.②spectroscopic uniform, the signal can be uniformly
allocated to the user.③compact structure, small size, can be
directly installed in the existing handover box, you do not need to
leave a lot of space for installation.
④single device has a
lot of shunt channels of, can achieve more than *2
road ⑤multi-channel is low cost, and its cost advantage is
obvious if it is divided more and more
At the same time, the
main drawback of the PLC splitter are as
follows:①device
production Technology is complicated, high technical threshold,
Chip is monopolized by foreign companies because of the domestic
companies producing mass packaging production seldomly② Compared
with FBT,its cost is much high, especially in the low channel
splitter.
