Optical Line Protection (Express Edition)
Optical Line Protection Equipment, abbreviated as OLP, is a crucial device used to protect optical fiber communication lines. Its core function is to monitor the status of the primary optical fiber line in real time. When the primary optical fiber experiences an interruption or deteriorates in performance (such as increased loss), it automatically or manually switches the service signal to the backup optical fiber line, thereby ensuring the continuity and reliability of communication and achieving the "self-healing" capability of the communication network.
In simple terms, OLP is like equipping your core communication optical cable with a "backup tire" and an "automatic switching system". When the main road (the primary optical fiber) becomes impassable due to an accident (disconnection) or congestion (significantly increased loss), the system can instantly redirect the vehicles (optical signals) to the backup road (backup optical fiber), ensuring that the service does not cease.

OLP Express Edition
● Ensuring business continuity: For industries such as finance,government affairs,energy,and internet,which have "zero tolerance" for business disruptions,OLP is a crucial safety guarantee.
● Enhance network reliability: Free the network from the vulnerable structure prone to single-point failures and build a highly available transmission network.
● Quick business recovery: The switching time is extremely short (usually at the millisecond level),much faster than manual emergency repairs,minimizing the interruption time and losses to the greatest extent.
● Reduce operating costs: Although it requires investment in backup routes,compared to the huge economic losses and reputational damage caused by business disruptions,the investment in OLP has an extremely high cost-effectiveness.
