cascaded device

Abstract

The application discloses a cascading device, which includes an optical splitting module, an optical channel conversion component and a gating mode controller whose normal working time is earlier than that of a central processing unit. The optical splitting module divides the optical signals of the uplink and downlink devices into two paths, which are respectively transmitted to the optical channel conversion component and the corresponding optical module. The optical channel conversion component is in an internal connection mode and an external connection mode based on the connection relationship between the pins and the connection relationship between the pins and the power supply and ground. The gating mode controller power signal, CPU status, optical module LOS signal, optical module received optical power information, and the connection relationship between the pins of the optical channel change component are controlled by controlling the connection between the pins of the optical channel change component and the power supply and ground. The connection relationship controls the optical channel change component to be in the corresponding working mode, so that when the cascading equipment is in an abnormal state, the entire cascading system can be effectively dealt with in an emergency, ensuring the normal operation of the cascading system, and improving the reliability and reliability of the entire cascading link. stability.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a cascading device. Background technique [0002] With the development of Internet technology, the scale of the network is getting larger and larger, and the current networking methods of servers and network processing equipment are also various. As a relatively common networking method, cascading is widely used in server networking and network processing. The device is in the network. [0003] Cascading means that the output of one system is used as the input of another system, and the cascading equipment of the entire system using the cascading method can be called a cascading system. In a cascaded system, the intermediate device that connects the upstream device and the downstream device is called a cascaded device. In the cascade system, the optical module is used as the cascade device to connect the uplink device and the downlink device, such as figure 1 an...

AI Technical Summary

Problems solved by technology

When the LOS signal of the optical module takes effect, the cascaded device cannot receive the signal, and the link of the entire cascaded system is interrupted.

When the receiving optical power of the optical module is too low, the cascaded equipment cannot receive signals normally, and the bit error rate, packet error rate, and packet loss rate of the entire cascaded system will increase

The cascading device is located in the middle of the network, and physically plays the role of connecting the upstream device and the downstream device. Once the cascading device in the middle fails or cannot receive and process data, it will directly cause the entire network link service to be interrupted.
