Overview
MXT-OR-860AN Self-healing optical receiver is designed for application of front-end and front-end sub. It is a kind of high-index, multi-functional and highly reliable optical device. Built-in dual optical receiving unit and automatic switching circuit. When one way optical signal fails, it will automatically switch to another way optical channel in order to achieve back-up switch, mainly used in self-healing ring network and ultra-trunk network.
Features
● Dual optical receiving channel, main / standby switch automatically to facilitate the implementation of redundant backup.
● FP, DFB return lasers can be optional.
● AGC controlling to ensure RF output level stable after two-way optical converting.
● Whole unit parameters through microprocessor controlling will display by the display screen.
● Double power supplies, automatic conversion.
● Built-in network management responder complying with international standard, and its working status can be detected remote and long distance.
● 19″ standard rack structure, machine components using modular design, convenient to maintain and upgrade.
