With the development of ultra-high speed and integration of optical communication, optical transceiver module also wants to adopt smaller volume and higher integration scheme, and the demand for parallel high-speed optical components is increasing rapidly. FA fiber arrays have very high requirements on materials and processing techniques, resulting in high costs, and have not been widely used in 10G rates. With the rapid promotion of high-speed transmission of 400G and 800G, FA with high density and small volume can be said to be a more ideal solution.
Fiber array is most commonly used in the packaging of planar optical waveguide splitter (PLC) and Array waveguide grating (AWG). With the explosive data traffic, the demand for fiber array in data center and 5G commercial growth, FA has also been more widely used in MEMS systems, sensors, silicon optics and other fields.
High speed optical component MT-FA
MT-FA is widely used for parallel transmission of optical transceiver modules, such as 100GPSM4 connected to external ports. By grinding the fiber array into a 42.5° mirror for total end reflection, the use of low-loss MT inserts with a V slot pitch tolerance of ±0.5μm provides the most compact parallel connection solution for optical transceivers.
AWG-FA-Receptacle
Receptacle is usually combined with FA, Capillary, Isolator, etc. to form optical connection devices, which are used as the external connection optical port of optical module to realize the connection and transmission of optical signals outside the module.
High-speed optical component bias preserving PM-FA
PM-FA is more used in coherent optical communication. Polarization maintaining fiber can keep the polarization state of light wave unchanged during transmission, which can give full play to the advantages of coherent reception. The polarization maintaining PM fiber array uses a V-Groove (i.e., V-groove) to mount a polarization maintaining fiber strip on the array substrate, which can achieve highly dense parallel transmission while ensuring the stability of light wave polarization.
Silicon optical integrated optoelectronic components, mode field conversion MFD FA
Mode field Diameter conversion FA provides a low-loss coupling method to a waveguide with a smaller mode field. A short section of ultra-high numerical aperture single-mode fiber (UHNA) is spliced to the tail fiber of a standard SM or PM fiber to realize the mode field conversion. This product is an ideal solution for high-speed silicon photonic transceiver module connection. WanChuang Communication technology can provide customized fiber diameter, such as 3.2μm / 3.3μm / 4μm / 5.5μm conversion to 9μm, using special assembly polishing process and high-precision V-groove substrate to achieve low insertion loss and high pitch-core. All quartz material, wide temperature resistance.
