Problems solved by technology

[0004] Generally speaking, the power connector needs to be designed separately. Its pins are longer than those of the signal connector to ensure that the power pins are in contact with the signal pins. In order to save costs, the same connector is used for power and signal, so that It may make the power supply not fully stable when the signal line is connected, which will have a negative impact on the working status of the front motherboard

Abstract

The invention provides a 120-gigabit Ethernet rear transition module based on BCM 84704, comprising a ZONE 3 connector, an electrifying control circuit, a signal converter, a monitoring module, a power module and an optical module, wherein the ZONE 3 connector, the electrifying control circuit, the power module and the optical module are sequentially connected; the signal converter is converted into SFI signals through 10-gigabit KR signals of the ZONE 3 connector; the SFI signals are input to the optical module; and the monitoring module monitors the state of the optical module and transmits the state of the optical module to a register in the optical module. The transmission of 120-gigabit Ethernet is realized by adopting the signal converter; and the 120-gigabit Ethernet rear transition module is simple in structure and in low cost, saves space and is widely used.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a BCM84704-based 120 Gigabit Ethernet rear card. Background technique [0002] Because the ATCA architecture only stipulates the mechanical dimensions and heat dissipation performance of the chassis and modules, it does not stipulate the specific functions and structures of the modules. The connection mode and signal definition between the front motherboard and the rear card are also not specified. In order to meet the requirements of the front motherboard to realize the system design, a custom IO expansion rear card module must be made. [0003] Computer platform architecture ATCA (Advanced Telecom Computing Architecture) is a computer platform architecture for communication systems, which specifies the mechanical structure and heat dissipation in detail. The rear card RTM (Rear Transition Module) specified in the ATCA standard is generally directly c...
