Product Description
Multi service optical transceiver the digital optical transceiver independently developed and produced by our company adopts the international most advanced digital optical fiber transmission technology to realize synchronous, distortion free and high-quality transmission on single core optical fiber with 4-way bidirectional video, 8-way forward switching value, 8-way reverse switching value, 2-way RS485, 2-way RS232, 2-way telephone and 4-way 10 / 100 / 1000m Ethernet (sharing). The optical transceiver adopts all digital video non compression transmission technology, which can meet the needs of users. It is easy to install and does not need on-site adjustment. Its optical module and core circuit adopt imported components with stable performance and are suitable for different working environments. For IP supermarkets, living quarters and military government units, the equipment adopts super large-scale integrated circuit design. The design is concise. It has the advantages of easy installation and debugging, maintenance free and stable performance. It is suitable for major communication operators, governments, enterprises and institutions. The optical transceiver is designed with a full industrial wide temperature range. At the same time, due to the use of optical fiber as the transmission medium, it has excellent performance, high temperature and cold resistance, can effectively prevent strong electromagnetic wave radiation interference, lightning impulse and power surge, and the communication quality is stable and reliable.
