Fiber connecting flange and light extracting module

Abstract

The invention discloses a fiber connecting flange comprising a coupling assembly. The coupling assembly comprises a first connecting member and a second connecting member which are centrally symmetrical when connected. The first connecting member comprises a first connecting portion and a first clamping portion. The first clamping portion has a first through hole therein axially perpendicular to afirst inner side surface. The upper end of the first connecting portion is provided with a recessed notch corresponding to the width and the position of the first clamping portion. The bottom of thenotch is in communication with the first through hole. The fiber connecting flange of the invention can be freely replaced in an original flange tray without changing the structure of the flange tray.Within a flange insertion loss standard value, a detection light wave in an optical fiber can be extracted and recognized. The fiber connecting flange is configured to gradually replace an existing mechanical flange so that the flange can be provided with eyes to lay a solid foundation for more bloated ODN intellectualization.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical fiber connecting flange and an optical module. Background technique [0002] In recent years, in the field of communication, optical fiber capable of high-speed and large-capacity transmission has become the mainstream of transmission lines and is being further developed. As a result, especially in optical communication related equipment such as data centers or telecommunication equipment rooms, construction work such as frequent changes, abandonment, and addition of optical transmission paths is carried out. The current management method is to stamp paper on jumpers. label to manage the optical fiber communication direction address and transmission content of this port, but the workload increases sharply due to a large number of changes or the need to re-print paper labels for demolition and construction operations, and the actual operator's mistak...

Problems solved by technology

Some detection light extraction technologies that exist at present realize the detection light extraction at the cost of destroying or changing the structure of the optical fiber and its transmission path, that is, the leakage of communication light is created by forcibly cutting the optical fiber and its outer ferrule The exit is used to obtain the leaked communication light as the detection light, but since the intensity of the communication light emitted by the optical transmitter is fixed in each optical fiber transmission path, and there are multiple active connection points in the optical fiber transmission path, the optical fiber joint is relatively Many, if the detection light is extracted directly at the active connector in this way of cutting the optical fiber, it will not only greatly damage the communication signal strength of the communication light, but also cause the original normal communication optical link to fail: optical cat Retired because the working optical power could not be reached
