A fiber optic coupler is a fiber optic connection device that uses the refraction properties of light in a waveguide to convert the optical signal at the input end into an optical signal available at the output end.

There are many types of fiber optic couplers: single-mode, multi-mode, strip and dispersion.

Introduction

A fiber optic coupler (optical coaxial transducer) is a device used to realize photoelectric conversion. It usually transmits the light emitted by the light source to the receiving end through an optical system through an optical fiber; it can also use a light-emitting diode or a laser as a light source to directly transmit the light to the receiving end.

classification by structure

Single-core (single-core): only one working wavelength;

Double-core (doubling-core): two operating wavelengths.

Bypass type: Coupling method without intermediate medium.

Application field

Used for electrical/optical conversion and signal transmission and processing, such as communication equipment, instrumentation, medical equipment, etc.
