Description

Technical Field

[0001] The utility model relates to the technical field related to optical fiber amplifiers, in particular to an optical fiber amplifier chassis with a stable structure. Background Art

[0002] Optical Fiber Amplifier (OFA) refers to a new type of all-optical amplifier used in optical fiber communication lines to achieve signal amplification. According to its position and function in the optical fiber line, it is generally divided into three types: relay amplification, pre-amplification and power amplification. Compared with the traditional semiconductor laser amplifier (SOA), OFA does not need to go through complex processes such as photoelectric conversion, electro-optical conversion and signal regeneration, and can directly amplify the signal with all-optical. It has good "transparency" and is particularly suitable for relay amplification in long-distance optical communications. The sub-shell and the main shell in the existing optical fiber amplifier chassis are connected by a card block and a bayonet, which is easy to be damaged during later maintenance and disassembly.
