Optical signal extraction device and method

Abstract

The invention provides an optical signal extraction device and method. The optical signal extraction device comprises an fiber connector adapter and a light extraction ceramic insert core arranged ina C-shaped ceramic sleeve of the fiber connector adapter, wherein the light extraction ceramic insert core comprises a ceramic insert core, a fiber and an optical detector, the fiber is a D-shaped fiber, the fiber is inserted into an inner hole formed in the axial direction of the ceramic insert core, one side of the ceramic insert core is provided with a notch, a top surface of a straight line segment of the fiber is a bottom surface of the notch, an optical detection sheet of the optical detector is close to the straight line segment of the fiber, and a distance between the top surface of the straight line segment of the fiber and a fiber core of the fiber is a preset value. The optical signal extraction device is advantaged in that extraction of the optical signal can be reliably realized so as to realize intelligent dynamic management of an optical interconnection port.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical signal extraction device and method. Background technique [0002] The optical fiber communication network level is mainly divided into trunk network, local network, metropolitan area network and access network. Optical devices between layers and between layers need to be connected through adapters (also known as fiber optic connector flanges, there are many types, such as FC, SC, ST, LC, D4, DIN, MU, MT, etc.) interconnection. The number of interconnection ports ranges from a few to as many as thousands. Different interconnection ports correspond to signal transmission services in different regions and cannot be confused. When a port is replaced or a service is changed, it is necessary to know exactly which port in which link and where, so that the operator can switch and operate accurately. With the sharp increase in business functions and quan...
