Technical Field

The utility model relates to the technical field of MT (mobile terminal) ferrules, in particular to a female MTP (multi-port) connector, a male MTP connector and an MTP connector thereof.

Background

CPO (co-packaging) refers to integrating silicon optical modules and CMOS chips together in advanced packaging (e.g., 2.5D or 3D packaging) to further enhance optical interconnect technology in data center applications in terms of cost, power consumption, and size. Current CPO (co-packagdoptics) light source modules employ 8-channel lasers, each of which has a particularly high light emission power consumption. Based on the above, the design of the CPO light source module changes the traditional light emitting mode, and the photoelectric interfaces are integrated at the golden finger end of the PCBA. At this time, based on the need for Multi-port individual light extraction, the conventional MPO (Multi-fiber pushon) scheme cannot be used. Therefore, a new MTP connector is needed to ensure the connection firmness and reliability.
