Fiber-pigtail-detachable plastic MiniDIL transmitter module with a tool-free optical connector

A fiber-pigtail-detachable plastic MiniDIL transmitter module using a tool-free optical connector and applicable to the OC 3 and OC 12 in the SONET/SDH standards has been developed as a cost-reducing solution. The newly developed optical connector works without a special tool to connect and disconnect it from the module. Transmitter fiber output of more than 0.4 mW, insertion loss of less than 0.3 dB, return loss of more than 55 dB, and a repeatability of more than 30 times were achieved.
