Optical fiber beam converter

Abstract

The invention provides an optical fiber beam converter, comprising an optical fiber insert core part (1) which is correspondingly connected with an optical instrument connector and a bare fiber adapter, the optical fiber insert core part (1) comprises a first optical fiber insert core (2) and a second optical fiber insert core (3), an optical fiber is respectively integrated in the first optical fiber insert core (2) and the second optical fiber insert core (3), and the optical fibers of the first optical fiber insert core (2) and the second optical fiber insert core (3) are connected. The optical fiber beam converter protects the optical instrument connector and realizes the accurate measurement of spectrum and polarization.

Description

technical field [0001] The invention relates to the technical field of spectrum measurement, in particular to an optical fiber beam converter for realizing the connection between an optical fiber and an optical instrument. Background technique [0002] When measuring spectrum and polarization, in order to realize the connection between optical fiber and optical instruments (such as spectrometers, light sources, etc.), it is necessary to use bare fiber adapters to realize the connection between optical fibers and optical instruments through bare fiber adapters, but if the bare fiber adapters are connected in this way If it is directly connected to the optical instrument, there will be a problem of damaging the optical instrument, thereby causing permanent damage to the optical instrument connector, and the replacement of the optical instrument connector usually requires expensive costs. [0003] At present, the solution in the prior art is to connect the optical instrument co...

Problems solved by technology

Considering that it has a filtering effect on the spectrum, it will also change the polarization state to a certain extent. Therefore, the use of optical fiber jumpers has obvious disadvantages when realizing accurate measurement of spectrum and polarization.

[0006] 2) In the connection between the optical fiber and the optical instrument, there is still a problem of mismatching the diameter of the optical fiber, that is, if the diameter of the optical fiber used is inconsistent with the diameter of the optical fiber inside the connector of the optical instrument, it will cause the two to fail to achieve an effective connection, thereby affecting the correlation.
