Abstract

The invention relates to the technical field of optical fiber communication, in particular to an optical fiber transceiver module based on plastic fiber and a plastic optical fiber communication system. The optical fiber transceiver module comprises an optical receiver and an optical sender, wherein the optical sender comprises an optical sending module for sending optical signals with the wavelengths being in a visible optical band and an optical sending module driver for driving the optical sending module to light; the optical receiver comprises an optical receiving module for converting input optical signals with the wavelengths being in the visible optical band into electric signals and a limiting amplifier for limiting and amplifying the electric signals output by the optical receiving module. The invention adopts the optical sending module with the working wavelength being in the visible optical band and a photoelectric detector with large detection area so that the optical fiber transceiver module can be applied to the plastic optical fiber communication.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a plastic optical fiber-based transceiver integrated optical module and a plastic optical fiber communication system. Background technique [0002] At present, the transceiver integrated optical modules in optical fiber communication all work in the non-visible light band (850nm, 1310nm, 1550nm, etc.), when the line fails, maintenance is very inconvenient; Quartz optical fiber is made of glass material, which is easy to break and has the disadvantages of difficult construction and maintenance. Therefore, it is very inconvenient to construct in Fiber To The Home (FTTH) or short-distance communication. [0003] Plastic optical fiber (Polymer Optical Fiber, POF), also known as polymer optical fiber, is an emerging optical fiber communication medium. ) compared with the quartz multimode fiber, the core diameter of the plastic optical fiber is as high as 200-1000μm, and...
