PM Fiber Splitter has numerous input and output ends. Fibre optic splitters may be used to separate light transmission in a network, making network interconnections more convenient. This article will help you learn more about optical fibre splitter manufacture, testing, and applications.


Fibre Optic Splitter


Fibre optic splitters are fundamental components of optical communication networks. These passive devices divide an input optical signal into two or more output routes, allowing the signal to be routed to several endpoints. Splitters improve fibre utilisation by reducing the need for individual cables for each endpoint.


FBT Splitters


FBT splitters are created by fusing and tapering several fibres together to provide the splitting action. FBT splitters have a customisable split ratio and are low-cost, making them ideal for small-scale applications. In contrast, PLC splitters separate optical signals using waveguides and thin-film filters.

PM PLC splitter provide a uniform dispersion of optical signals, improved performance, and increased bandwidth, making them perfect for large networks or applications that require larger split ratios. It's worth noting that, given the ubiquitous usage of PLC splitters, consistent split ratios may not always match precise resource allocation requirements. Unbalanced PLC splitters are progressively hitting the market.


How to Make a Fibre Optic Splitter?


A passive optical splitter is manufactured in five steps. Each phase necessitates rigorous control and management of numerous elements such as environment, temperature, and precise assembly and equipment. We will now offer a full introduction, utilising PLC splitters as an example.


Step 1: Component Preparation


A passive optical splitter consists of three basic components: input and output fibre arrays, as well as a chip. The design and assembly of these are critical to developing a high-quality PLC splitter. The PLC circuit chip is inserted in a piece of glass wafer, which is polished at both ends to provide a very exact flat surface and excellent purity. The v-grooves are then ground into a glass substrate. A single fibre or numerous ribbon fibres are attached to the glass substrate. The assembly is then polished.


Step 2: Alignment


After preparing the three components, they are placed on an aligner stage. The input and output fibre array are positioned on a goniometer stage to align with the PLC chip. The fibre array's continuous power level output is used to monitor physical alignment with the device.


Step 3: Cure


The assembly is subsequently placed in a UV (ultraviolet) chamber, where it is completely cured at a regulated temperature.


Step 4: Packaging


The naked splitter is aligned and assembled into a metal housing, with fibre boots at both ends. The completed product must then undergo a thermal cycling test to confirm its quality.


Step 5: Optical Testing


In terms of testing, three critical factors such as insertion loss, uniformity, and polarisation-dependent loss (PDL) are done on the PM fibre splitter to guarantee that the optical properties of the produced splitter comply with the GR-1209 CORE specifications.
