PLC Splitter

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.

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 loss

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 of splitting ratio. Between the different fiber coupler, the insertion loss of the device making the difference and don't 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, fiebercasa 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 ) .

FiberCasa provides PLC Splitter with multiple channels of 1×N and 2×N, including 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, and 2×2, 2×4, 2×8, 2×16, 2×32, 2×64. The splitter with lower insertion loss, high stability and reliability, good, uniformity, the PLC Splitter could meet different requirement for the FTTx OSP network.

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

 

Note 1: All measurement at room temperature and excluding connector loss . 
Note 2: For devices with connectors, insertion loss will be 0.3 dB higher, return loss > 50 dB ( UPC ), >55 dB ( APC ).
