The PLC splitter is a crucial optical power distribution device that uses a quartz substrate to evenly distribute light signals in fiber optic networks. It offers advantages like low insertion loss, compact size, and cost-effectiveness for large channel numbers, though it faces challenges such as high manufacturing complexity and costs. Various configurations and specifications are available, supporting multiple channel outputs and connector types to meet diverse networking needs.

1. PLC Splitter
Brief introduction
PLC Splitter is a kind of waveguide optical power distribution device integration
based on a quartz substrate plate , like coaxial cable transmission system,
network system also needs to be light signal coupling, branches, distribution
and the optical divider is needed for implementation.It is one of the most
important fiber link passive components, fiber optic tandem device having a
plurality of inputs and a plurality of output terminals, especially for passive
optical network (EPON, GPON, BPON, etc.) to connect the central office and
terminal equipment and allow branching optical signals.
Advantage
(1) Loss is not sensitive to transmit light wavelength, can meet the needs of the
different wavelength of transmission.
(2)Uniform light, signal can be evenly distributed to the user.
(3) compact, small size, can be installed directly in the various existing junction
box, without specially designed to stay out of a lot of installation space.
(4) single device bypass passage lot, it can reach 32 or more.
(5) Multi-channel of low cost, the more points the large ones, more obvious
cost advantage.
Shortcoming
(1)Complex manufactory, high technical threshold, the current chip are
monopolied by foreign companies, only a few of companies can produce large
quantities of packaging in our country.
(2) The cost is higher relative to the melting cone type divider, especially at a
disadvantage when in the aspect of low channel way more .

2. Component
Internal controlled by a PLC optical splitter chip and fiber array of coupling.
Chips make grow in the quartz substrate using semiconductor process, a layer
of light waveguide chip is an input terminal and N output waveguide. And then
on both ends of the chip input and output optical fiber array, respectively.
External is made up of the ABS and square steel box, cable and fiber-optic
connectors.
Technical Specifications
Insertion loss
The insertion loss of the optical splitter means each output relative to the input
loss on the number of dB, the mathematical expression is: Ai = -10lg Pouti / Pin,
where Ai is the insertion loss means the i-th output port; Pouti is the i-th output
port optical power; Pin is the optical power value input.
Additional losses
Additional loss is defined as the sum of all output ports with the input optical
power loss DB number. It is worth mentioning that, for fiber optic couplers,
additional losses are reflected in the device manufacturing process quality
indicators, reflects the inherent loss of the device production process, the loss
is as small as possible, is to produce the quality of the merits of the
assessment indicators. The insertion loss is only that the output power of each
output port, not only has the inherent loss of factors, but considering the effect

3. of splitting ratio. Between the different fiber coupler, the insertion loss of the
device making the difference and do not reflect the quality of the pros and
cons.
Divider ratio
Divider ratio is defined as the light output ratio of each output port in the
system application, optical node ratio is based on the need of actual system of
optical power, determines appropriate ratio ( except the average allocation ),
optical divider ratio is related to the wavelength of light transmission. For
example, a branch of light transports in 1.31 micron, the divider ratio of two
output is 50:50 ; In 1.5 μm light transmission, when it becomes 70:30 ( the
reason of this circumstance is that the optical divider has the certain bandwidth,
which is transmitted when the radio unchanged ). Therefore, we must indicate
the wavelength when the optical splitter is made.
PLC splitter is based on planar lightwave circuit technology, therefore,
fibercasa could offer PLC splitter with multiple package type like Bare fiber
type PLC Splitter, Blockless type ( Micro Module type ) PLC Splitter, Cassette
type ( ABS box type ) PLC Splitter, Insert type PLC Splitter, Tray type PLC
Splitter, and Rack mount type PLC Splitter, the fiber interface support SC, FC,
LC or customized with other types of connectors. The connector polishing type
support UPC and APC ( with 8 degree angle ).

4. FiberCasa provides PLC Splitter with multiple channels of 1xN and 2xN,
including 1x2, 1x4, 1x8, 1x16,1x32,1x64, and 2x2, 2x4, 2x8, 2x16, 2x32, 2x64.
The Splitter with lower insertion loss, high stability and reliability, good,
uniformity, the PLC splitter could meet different requirement for the FTTx OSP
network.

5. Note: Provide SC,FC,LC,ST connectors for choice; APC or UPC polishing type
as customer request.
