The OLP optical protection board is a protection system developed by 3C-LINK for fiber optic line backup. It adopts advanced optical automatic switching modules and is an optical device used for primary and backup optical path switching in the field of fiber optic communication. It can automatically identify the signal status of the primary and backup system optical paths and perform instantaneous switching of the optical path to ensure the normal operation of the primary optical cable in the event of a complete obstruction, thereby improving the service quality of the service provider. The OLP optical line protection board is widely used in primary and backup protection of various trunk lines and in networks requiring various optical path switching. Its advantages lie in the direct utilization of optical signals in the optical line, compact size, and cost-effectiveness, making it widely used in various optical transmission fields.
Supports optical line protection for both single-mode and multimode fiber Supports dual-fiber bidirectional and single-fiber bidirectional protection modes. Supports 1+1 (dual-transmitter dual-receiver) and 1:1 (transmitter selection receiver selection) protection modes. Wide optical power monitoring range: -50dBm to +25dBm. Short optical path protection switching time:
* Support multiple working modes of automatic or manual switching
* Supporting real-time monitoring of main and backup routes
* Fast response: switching time<20ms
* Support automatic non-return and automatic return functions, automatic return time can be set to adapt to a variety of application scenarios
* Support panel button operation. The system can be operated by button on-site without a management card
* Support power-off and power-on retention functions
* OLP cards and network management cards are independent of each other and have no influence on each other
* Support multi-kinds of graphical interface network management, such as SNMP, Web
* Support AC power 220V, DC power -48V, and 1+1 power input protection
* Standalone 19inch 1Unit Chassis
