Digital fiber repeater system with backup and switching method

Abstract

The invention discloses a digital optical fiber repeater with a backup and a switching method. The repeater mainly comprises a local machine and at least one remote machine, the plurality of main optical modules of the local machine are connected with the main optical modules of the corresponding remote machines, and the multiple optical modules of the local machine are connected with the standbyoptical modules of the corresponding remote machines, and each remote machine is connected in sequence. The local machine is mainly composed of a local main control board, a local intermediate-frequency board, and a local power supply module, and the remote machine is composed of a remote main control board, a remote intermediate-frequency board, a remote power supply module, and a power amplifiermodule. According to the digital fiber repeater system with backup and switching method, the local intermediate-frequency board, the remote intermediate-frequency board and the power amplifier moduleare stripped from the main control board by adopting a modular design, various modules are added or removed according to the use requirement; The instantaneous switching is realized through the hardware and the software in the system, and the user experience is basically not affected; meanwhile, the equipment cost is reduced, the design scheme is simplified, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of repeaters, and mainly relates to a digital optical fiber repeater system with backup and a switching method. Background technique [0002] The existing digital optical fiber repeater system needs to be backed up in some applications where the requirements are high or the environment is relatively harsh; in existing applications, the current backup is done by adding one or more sets of the same equipment This networking implements the backup function. Although this method can also realize backup networking, on the one hand, this processing method has high equipment costs, and on the other hand, the networking is complicated, which puts forward higher requirements on the performance of the equipment itself and on-site installation and commissioning personnel, which is not conducive to large-scale production lines. Network operation, and at the same time, it does not meet the current requirements for green ...

AI Technical Summary

Problems solved by technology

This networking method consumes a lot of equipment costs, and at the same time, because the number of equipment doubles, it increases the difficulty of network maintenance; because it is two sets of independent networking equipment, it is impossible to quickly and automatically judge the status of the active / standby link , when the primary link fails and needs to be switched to the standby link, the standby link must be triggered manually or in the background, resulting in slow network response time, which seriously affects network operation and user experience
