The PINI photodiode receives the optical signal from the POF and converts it into a weak electrical signal. After pre-amplification, it is sent to the amplification and equalization circuit to complete the optical / electrical conversion. The light detection adopts the direct detection method, which is simple, economical and practical and can fully meet the requirements of short-distance communication. In the receiver, a three-line receiver chip MC10H116FN is selected, which can complete the amplification and equalization functions, and the delay is very small, only 1ns.
In addition, if the MC10H116FN is provided with a stable 3V bias voltage, it will have the function of Schmitt trigger and adjust the wave shape and eliminate the noise. From the corner, it constitutes a complete plastic optical fiber transceiver. Using standard single-row 9-pin connector, it can be directly connected to the optical network card.
Due to the large amount of information exchange between various home appliance units in the home intranet, in order to ensure high-quality audio-visual effects, the use of traditional audio and video cables and twisted-pair cables as networking cables can no longer meet the requirements. Only optical fibers can load so huge Audio, video and Other data streams. Although glass fiber has high bandwidth and low transmission loss, it is difficult to popularize and apply it in home networking due to its high price, difficulty in fusion and termination. The plastic optical fiber has the advantages of good flexibility, light weight, high bandwidth, high reliability, and low cost. Especially the connection is very convenient, which is more and more popular in the digital home appliance industry and consumers. Due to its many advantages, plastic optical fiber will surely become the main transmission medium for short-distance communication networks. Therefore, many countries in the world have invested heavily in active development.
