Description
Technical Field
The invention relates to the technical field of optical communication, in particular to a coupling clamp and a coupling method for an FA and an isolator.
Background
An optical isolator is a passive optical device that allows only unidirectional light to pass through, and its principle of operation is based on the non-reciprocity of faraday rotation. Light reflected by the fiber echoes can be well isolated by the optical isolator. The optical isolator mainly uses the faraday effect of the magneto-optical crystal. The optical isolator has the characteristics of low forward insertion loss, high reverse isolation and high return loss. The optical isolator is a passive device which allows light to pass in one direction and prevents the light from passing in the opposite direction, and has the function of limiting the direction of the light, so that the light reflected by the optical fiber echo can be well isolated by the optical isolator, the light wave transmission efficiency is improved, and adverse effects of backward transmission light generated by various reasons in an optical path on a light source and an optical path system are prevented. For example, the installation of an optical isolator between a semiconductor laser source and an optical transmission system can greatly reduce the adverse effect of reflected light on the spectral output power stability of the source. In high speed direct modulation, direct detection fiber optic communication systems, the backward transmitted light can create additional noise that degrades the performance of the system, which also requires an optical isolator to eliminate. The optical isolator is arranged at two ends of the doped optical fiber in the optical fiber amplifier, so that the working stability of the optical fiber amplifier can be improved, and if the optical isolator is not arranged, the backward reflection light enters the signal source (laser) to cause severe fluctuation of the signal source. In a coherent light long-distance optical fiber communication system, an optical isolator is arranged at intervals, so that the power loss caused by stimulated Brillouin scattering can be reduced. Therefore, the optical isolator plays an important role in optical fiber communication, optical information processing systems, optical fiber sensing and precision optical measurement systems. It attenuates little light signal transmitted in the forward direction and attenuates much light signal transmitted in the opposite direction, forming a unidirectional path for light. The optical isolator is connected between the laser and the transmission optical fiber, so that reflected light generated from the end face of the far end of the optical fiber, the interface of the optical fiber connector and the like in a circuit can be effectively restrained from returning to the laser, the stability of the working state of the laser is ensured, and noise caused by the reflected light of a system is reduced. This is of great importance for high-rate optical fiber communication coherent optical fiber communication systems.
However, in actual production, since the manual operation of the isolator is relatively small (0.4x0.4x0.75mm), the coupling efficiency is relatively low, the coupling quality is unstable, and the product consistency is poor.
