①Polarization Maintaining Fiber Array（PM-FA）
Description：
MFD-FA provides a method of low loss coupling to a waveguide with a small mode field. A small section of ultra-high numerical aperture single-mode fiber (UHNA) is spliced to the tail fiber of standard SM or PM fiber to realize mode field conversion. The product is an ideal solution for connection on high-speed silicon photonic transceiver module, and can provide customized mode field diameter, such as 3.2μm/3.3μm/4μm/5.5μm to 9μm. It adopts special assembly and polishing process and high-precision V-groove substrate to realize low insertion loss. It is made of all quartz and resistant to wide temperature.

⑥Fiber Array（FA）
Description：
Fiber array (FA) is an array formed by using V-groove substrate to install a bundle of optical fibers or an optical fiber band on the substrate at specified intervals. Optical fiber array mainly includes substrate, pressing plate and optical fiber. The V-groove needs to use a special cutting process to achieve accurate optical fiber positioning. The exposed optical fiber part without optical fiber coating is placed in the V-groove, pressurized by the pressurizer component and fixed with adhesive, and the end face is optically ground to finally form an optical fiber array.
