MT/FA fiber optic patch cords are mainly used in parallel optical technology modules (QSFP) to connect internal optical lenses and external ports to accommodate signal transmission of optical modules. A fiber optic array (FA) is an array in which a V-groove substrate is used to install fiber bundles or fiber ribbons according to specified spacing on the substrate, where the fibers are precisely positioned for connection to a PLC at the front end . Fiber arrays are mainly used to transmit information in fiber optic communications, and the main applications include planar optical waveguides, arrayed waveguide gratings, active/passive array fiber optic devices, MEMS, and multi-channel optical modules. .
