FE1 Fiber Optic Modem

Overview

The core part of FE1 Fiber modem is ASIC chip. The chip adopts reducing jitter unique patented technology, digital lock and clock extraction techniques, the 2M interface anti-interference technology, etc. so that the modem is particularly suitable for situations requiring high reliability and fully assistant functions, such as Mobile, China Unicom, telecommunications, electric power, public security, military, highway, aviation, and other special communication network. Structures of hardware and software inside the device are modular. Hardware uses a large-scale AISIC chips integrating encoding, decoding, information insertion and alarm, which simplifies the circuit. Thereby the reliability of the machine is improved.
