CSFP optical transceiver module

Abstract

The invention discloses a CSFP optical transceiver module, which includes a main board, a first bidirectional transceiver, a second bidirectional transceiver, a first flexible circuit board and a second flexible circuit board, wherein the main board is provided with a main board top layer and a main board bottom layer; one end part of the main board top layer is provided with a first bonding pad, the main board is connected with one end of the second flexible circuit board through the first bonding pad, and the other end of the second flexible circuit board is connected with the second bidirectional transceiver; and one end part of the main board bottom layer is provided with a second bonding pad, the main board is connected with one end of the first flexible circuit board through the second bonding pad, and the other end of the first flexible circuit board is connected with the first bidirectional transceiver. According to the CSFP optical transceiver module, the main board is connected with the two bidirectional transceiver directly through the flexible circuit boards, thereby simplifying the manufacturing process, improving the production efficiency, and reducing the design and manufacturing costs; welding points are reduced in the manufacturing process, so that failure caused by insufficient welding is avoided, and the stability and reliability of products are greatly improved.

Description

technical field [0001] The invention relates to a CSFP (Compact SFP, compact and miniaturized hot-swappable optical transceiver module, hereinafter referred to as CSFP optical module) optical module, which is mainly used in the field of optical fiber communication and is related to the physical interface of the access network. Background technique [0002] The optical transceiver module is an important part of the optical fiber communication network, and its core function is to provide a photoelectric conversion interface between various transmission networks. With the rise of a series of hot applications such as fiber-to-the-home and the further demand for low-cost optical transceiver products and high link capacity, CSFP optical transceivers emerged as the times require. The CSFP optical module greatly reduces the external dimensions of the optical module and communication system equipment, while doubling the port density and information throughput, it also reduces the...
