OTN6500 OLP Optical Line Protection Card Board for DWDM Network

Types :

What is Optical Line Protection?
An optical line protection system (OLP) uses vacant optical fiber from different routes to build a backup path. by real-time monitoring the power status in working fiber, it can automatically switch from working fiber to backup fiber when the power value of working fiber is lower than a user-defined threshold.

What is OLP in DWDM?
The optical line protection unit implements the dual-fed and selective receiving of one channel of signals. ... The optical switch selects one from the two channels of signals based on the optical power of the signals. In this way, the selection of signals from the working and the protection channels is achieved.

What is OLP in networking?
OLP-Optical Line Protection is a device that is used in the protection of network transmission lines, it can realize optical power monitoring and automatic switching. In an optical communication networks, OLP constantly monitors the optical power of working optical fiber and standby optical fiber.

Optical Line 1+1 Protection Equipment Functional Structure

Optical Line 1+1 Protection Equipment Functional Structure

This OLP optical protection card is mainly used to assist the wavelength division system to complete optical layer protection solutions such as optical line 1+1 protection and optical wavelength 1+1 protection. It can monitor the primary and backup routing optical paths in real-time.

In the event that the fiber core is blocked or degraded in performance, it can implement the secure rearrangement automatically in the main and standby fiber core, so as to guarantee optical signals in the system line recover quickly. OLP technology is to complete the routing switch operation in the optical layer.

The optical layer protection has incomparable advantages over the protection of upper services, and it is the best solution to provide the user with uninterrupted communication.
