Abstract

The invention provides a 400 Gbps hot-plug high-speed optical transceiver module which is suitable for the optical communication technical field. The 400 Gbps hot-plug high-speed optical transceiver module comprises an optical interface unit, a photoelectric transceiver unit and an electrical interface unit; the photoelectric transceiver unit is used for achieving the functions of photoelectric conversion and high-speed electrical signal processing through a photoelectric transceiver chip; the internal working process of the photoelectric transceiver chip comprises receiving an electrical signal input through the electrical interface unit by a transmitting terminal data clock recovery circuit, loading the electrical signal to a laser after the pretreatment through a driving circuit, converting the high-speed electrical signal into a high-speed optical signal through the laser, reusing the high-speed optical signal through a wavelength division multiplexer to be output, reusing the received optical signal into a 16-channel optical signal through a wavelength division demultiplexer to be transmitted to an optical detector and transmitting the 16-channel optical signal to a trans-impedance amplifier and a receiving terminal data clock recovery circuit after photoelectric conversion to be processed. According to the 400 Gbps hot-plug high-speed optical transceiver module, the factors such as the cost, the transmission loss, the chromatic dispersion and the size are considered to select different optical transceiver modules and accordingly the long-distance single-mode optical fiber transmission or the short-distance multimode transmission is implemented.

Description

technical field [0001] The invention belongs to the technical field of optical communication, in particular to a 400Gb / s hot-swappable high-speed optical transceiver module. Background technique [0002] In recent years, as the demand for high-quality video services, cloud computing, large-scale data centers, and fixed / mobile Internet applications continues to grow, people require more and more information and faster information transfer rates. Operators also realize that bandwidth requirements will continue to increase with the data explosion, and they have accelerated the pace of evolution of transmission networks, upgrading from 40G / 100G to 400Gbps to meet people's eager demand for speed. [0003] In March 2014, the CDFP industry alliance released the multi-source agreement CDFP MSA (400Gbps form-factor pluggable Multi-sources Agreement) for 400G hot-swappable modules, which is used to standardize the mechanical and electrical interface design of 400G modules. The specifi...
