Optical fiber signal direct guide type optical module

Abstract

The invention relates to an optical fiber signal direct guide type optical module which comprises a connector, a control circuit board and a plastic optical fiber, the control circuit board is connected to the connector, a functional optical module is arranged on the control circuit board, the plastic optical fiber is provided with an optical fiber end face, and the optical fiber end face corresponds to the functional optical module. The distance L between the end face of the optical fiber and the top face of the functional optical module is controlled to range from 50 micrometers to 150 micrometers, optical signals emitted by the end face of the optical fiber can be directly received by the functional optical module, and optical signals emitted by the functional optical module can also directly penetrate through the end face of the optical fiber to be received by the plastic optical fiber. The plastic optical fiber comprises an optical fiber core and a wrapping layer, the wrapping layer wraps the optical fiber core, an optical transmission reflecting surface is formed between the optical fiber core and the wrapping layer, and the ratio D1 / D2 between the aperture D1 of the optical fiber core and the aperture D2 of the wrapping layer is larger than or equal to 0.6 and smaller than 1.

Description

technical field [0001] The invention relates to an optical module, in particular to a direct-guided optical module in which an optical fiber signal in a plastic optical fiber is directly guided into a functional optical module. Background technique [0002] The optical module is called the optical transceiver integrated module. It is the core device in optical communication. It can complete the process of converting optical signals into electrical signals and converting electrical signals into optical signals. It is mainly composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: receiving and emitting. In simple terms, its receiving part is responsible for converting optical signals into electrical signals, and its transmitting part converts electrical signals into optical signals. [0003] In order to ensure the quality of long-distance signal transmission, the optical transmission part of the current opt...

Problems solved by technology

[0009] like figure 2 As shown, the core aperture 5 of GI-POF is relatively small, and the common aperture can be as small as about 100 microns. Small processing is extremely difficult, so its price is quite expensive, so the cost of optical modules produced by GI-POF is extremely high
