A 10-Gbps × 12-channel pluggable parallel optical transceiver based on CXP interface specifications

摘要

A novel 10-Gbps × 12-channel pluggable parallel optical transceiver is designed and fabricated. Compared with other optical transceivers, this transceiver emphasizes small size, high-density, low power consumption, and high transmission speed. Most importantly, its optical coupling structure is simplified to promote cost-effective large-scale production. This transceiver is electrically pluggable and consists of transmitter and receiver modules linked by parallel multi-mode fibers. Each module consists of a six-layered high-speed, high-density printed circuit board, the size of which is 30 mm × 18 mm × 1 mm, packaged with optoelectronic devices and corresponding control chips. The printed circuit boards not only provide a high-speed electrical connection between the I/O interfaces and high-speed chips, but they also supply power and ground planes to those chips. End-to-end error-free transmission at 10.3125 Gbps was obtained for a 2 31-1 non-return-to-zero pseudo-random bit sequence.
