Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. The pluggable optical transceiver modules include an on-board application-specific integrated circuit (ASIC), optical transceiver, and an optical socket allowing a fiber to connect to the optical transceiver. Pluggable optical transceiver modules implement an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in manner that does not require the fiber jumper, while ensuring tight alignment tolerances. In some embodiments, optical transceiver modules are designed to achieve a direct opt-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, an adaptor is distinctly designed, directly connecting an external cable to the optical socket (eliminating the use of fiber jumper and faceplate connector in the module). In some embodiments, a rigid body opto-mechanical interface is used.

A method for designing a high-speed multichannel optical module. Components in an optical module are classified into a circuit part and an optical path part according to functions, and the circuit part and the optical path part are separately processed and then assembled to be an optical module. Thus, modular production is implemented, and multiple parts can be processed at the same time, thereby improving the production efficiency. Moreover, if any fault occurs to either of the parts, the part can be independently replaced and maintained, thereby preventing the entire optical module from being scrapped, facilitating control of the production costs, and improving the yield rate. Also disclosed in the present invention is a high-speed multichannel optical module, which is manufactured according to the design method above. The high-speed multichannel optical module employs a modular structure, and comprises a circuit part and an optical path part which are electrically connected. The structure is simple, and expansion and upgrade are facilitated.

An optical transceiver according to an aspect of the present embodiment is an optical transceiver configured to be inserted to and extracted from a cage of an apparatus along a first direction. The optical transceiver includes a device generating heat, and a housing having a rectangular parallelepiped shape with long sides extending along the first direction. The housing includes an internal space housing the device, and an outside part configured to be exposed to an outside of the cage. When the housing is engaged with the cage, the outside part having an air intake part configured to bring an outside air into the internal space for cooling the device.

A connector includes a cage and a heat-radiation element. A top wall of the cage includes an opening, and first engaging structures extending from the top wall of the cage toward an outside of the cage at a periphery of the opening. The heat-radiation element is disposed on the cage corresponding to the opening, and first notches corresponding to the first engaging structures are disposed on side walls of the heat-radiation element. Each first engaging structure passes through the corresponding first notch to engage the heat-radiation element on the cage. The cage has a receiving cavity and supporting structure at a bottom of the receiving cavity. When a mating connector is inserted into the receiving cavity, a bottom of the mating connector is supported by the supporting structure, a top of the mating connector abuts against the heat-radiation element through the opening, and the heat-radiation element remains substantially stationary.
