HT-OR-860AN Self-healing CATV 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
1. Dual optical receiving channel, main / standby switch automatically to facilitate the implementation of redundant backup.
2. FP, DFB return lasers can be optional.
3. AGC controlling to ensure RF output level stable after two-way optical converting.
4. Whole unit parameters through microprocessor controlling will display by the display screen.
5. Double power supplies, automatic conversion.
6. Built-in network management responder complying with international standard, and its working status can be detected remote and long distance.
7.19' standard rack structure, machine components using modular design, convenient to maintain and upgrade.
