Optical splitter is the optical signal shunt or combined light passive devices, generally the same wavelength of the optical signal separation or joint road. According to the optical splitter port arrangement is different, can be divided into symmetrical star splitter and asymmetrical tree splitter; according to the type of fiber can be divided into single-mode optical splitter and multi-mode optical splitter ; According to the bandwidth can be divided into narrowband optical splitter and broadband optical splitter. Commonly used for the production of melting drawer (FBT) type splitter, planar optical waveguide (PLC) splitter.
Fiber PLC Splitter package is the difficulty of manufacturing optical splitter, packaging technology directly affects the performance of the product, generally use stainless steel.
Different from the traditional discrete devices, PLC devices using semiconductor technology, can be different functions of optical components integrated into a chip, is to achieve integrated optoelectronic devices, modular, miniaturization of the basic process technology. PLC splitter chip using semiconductor technology (lithography, corrosion, development technology) production. The optical waveguide array is located on the upper surface of the chip, and the shunt function is integrated on the chip, that is, on a chip.
Fiber PLC splitter is one of the main raw materials for fiber arrays. The fiber array is made of V-groove, using a special bonding process to achieve accurate four-year high-grade fiber and high reliability to meet different needs. Fiber PLC splitter is the technique of aligning the individual light paths on the plane waveguide splitter with the fiber in the ray array and then bonding it with a specific coupling. The alignment accuracy of the PLC splitter and the fiber array is the key to the technology.
Fiber PLC Splitter consists of a PLC optical splitter chip and a fiber array coupled at both ends. The chip is grown on a quartz substrate by a semiconductor process. The chip has an input terminal and N output waveguides. And then at both ends of the chip are coupled to the input and output fiber array. It has an external ABS box and square steel pipe, fiber optic cable and optical fiber connector.
