Optical module

Abstract

The invention discloses an optical module and solves the problem of PCB wiring difficulty in the prior art. The optical module comprises a circuit board, a lens assembly and a fiber adapter corresponding to the lens assembly, wherein the driving chip of the lens assembly communicates with electric signal interfaces on a specific position area on the circuit board to reduce intersects of communicating channels between the electric signal interfaces on the specific position area and the driving chip. The electric signal interfaces on the specific position area are determined according to the types of the optical assemblies driven by the driving chip, and types and arrangement of each electric signal interface on the circuit board. A jumper wire device of the lens assembly communicates with the fiber adapter through an optical fiber ribbon. The sequence of the optical fiber ribbon accessing to the channels on the jumper wire device side is different from the sequence of the optical fiber ribbon accessing to the channels on the fiber adapter side. The optical module accesses the electric signal interfaces on the specific position area to the driving chip, which reduces or eliminates intersects of PCB wirings.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical communication, and in particular, to an optical module. Background technique [0002] In the field of high-speed parallel optical modules, with the increase of optical paths, the improvement of module integration, and the continuous improvement of transmission rates, especially the multi-channel parallel optical modules with a rate of 25Gbps, the PCB board, the length of differential signal traces, and the number of vias in the module Wait for higher requirements. Cabling is becoming more and more difficult to control to an optimal level. Especially when there are many optical paths, such as high-density and high-speed parallel optical modules with 12 / 24 / 48 channels, there are usually multiple ICs that output enough high-speed differential signal channels in parallel, and the routing of high-speed differential signals on the PCB will be very complicated. It will be difficul...
