What is OLP?

OLP (Optical Fiber Line Auto Switch Protection Equipment) – optical fiber line automatic switching protection device. The optical fiber automatic switching protection system (OLP for short) is an automatic monitoring and protection system that is independent of the communication transmission system and is completely built on the physical link of the optical cable.
Line protector OLP is a transmission device that works at the optical layer. It has the characteristics of independent and transparent transmission signals, safety and reliability, and fast fault recovery. It can help users build an optical communication network that is non-blocking, highly reliable, safe, flexible, and highly resistant to disasters.

What protection methods are available?

In terms of protection methods, they are divided into the following two types:

①1+1 protection method

The 1+1 optical path protection card has the characteristics of independent and transparent transmission signals, safety and reliability, and fast fault recovery. It can help users build an optical communication network that is non-blocking, highly reliable, safe, flexible, and highly resistant to disasters.

②1:1 protection method

OLP protects the line through 1:1 (selective sending and selective receiving) protection mode. At the same time, the 1:1 protection mode will reduce the loss much compared to 1+1, so this protection mode is also used in the transmission link. are used extensively.

In what scenarios is OLP often used?

OLP optical line protection equipment is a functional device used in the field of optical fiber communication to automatically switch between master and backup optical paths. It can monitor the optical signal status of the main and backup links in real time. When the main link optical cable fails, the system automatically switches to the backup link. transmission, protecting the normal operation of the system and improving system stability. It is widely used in various important optical network transmissions, such as operator backbone networks and 5G base station fronthaul, government and enterprise backbone networks, bank financial dedicated lines and other fields.
