OLP Optical Line Protection Subsystem

The OLP optical line protection subsystem launched by Guangzhou Sintai Co., Ltd is based on the advanced development of optical switch technology. It’s an automatic monitoring and protection system independent of communication transmission system and completely based on the physical link of optical cable. The system can automatically switch the signal to the optical fiber of the protection path when performance deterioration or blocking of work path is detected. In this way, an optical communication network with high reliability, safety, flexibility and strong disaster resistance is established.

Product Feature

l Applicable to all kinds of optical communication system

l Support line protection of dual fiber and single fiber transmission network

l Support multiple working modes of automatic or manual switching

l Supporting real-time monitoring of main and backup routes

l Fast response: switching time<20ms

l Support automatic non-return and automatic return functions, automatic return time can be set to adapt to a variety of application scenarios

l Support panel button operation. The system can be operated by button on site without management card

l Support power-off and power-on retention functions

l OLP card and network management card are independent of each other and have no influence on each other

l Support multi-kinds of graphical interface network management, such as SNMP, Web

l Support AC power 220V, DC power -48V, and 1+1 power input protection

l 1U pluggable rack mount, flexible capacity configuration
