Shanghai Optical Releases PLC Splitter Chip

Shanghai Optical Integrated Optical Co., Ltd. announced a PLC splitter chip for multimode optical fibers that can be used for data switching centers, military applications, fiber optic sensing, etc., with large channel capacity, fast speed, and short transmission distance (below 1000 meters). This achievement has successfully filled the gap in the industry.

In popular FTTX networks, long-distance low-loss single-mode fiber splitters are commonly used. But in fact, in the occasions such as data exchange center, military applications, optical fiber sensing, etc., where the channel capacity is fast, and the transmission distance is short (below 1000 meters), multi-mode optical fibers are often used for signal transmission, and there are also a large number of signal branching requirements. Shanghai Optical core used ion exchange technology to develop a multi-mode optical splitter chip and successfully filled the gap in the industry.

Shanghai Optical Core stated that according to application requirements, 1*2 chips with different splitting ratios such as 50/50, 20/80, and 10/90 can be produced. Compared with fused taper, the PLC multimode shunt device has the advantages of wavelength insensitivity (which can simultaneously satisfy wavelengths of 850nm and 1310nm), a wide operating temperature range (-40-+85) and modeless selectivity. The Oita road has the advantage of being smaller than the case (1*4, 1*8).

In the multi-mode splitter coupling process, the outer diameters of the multimode fiber and the single-mode fiber are the same, and the Fiber Array simply replaces the single-mode fiber with an OM1 or OM3 multimode fiber.

In addition, Shanghai Optical core can also customize the splitter chip that matches the plastic optical fiber according to customer requirements. Due to its low cost and excellent bending resistance, plastic optical fibers have specific application values ​​in certain applications. However, a plastic optical fiber has a core diameter of 80 μm or more and cannot be made into a 3 dB coupler by fused taper. So now we are using opto-optical switches for signal splitting. Using passive multimode splitter chips can save a lot of cost and power.
