OLP Optical Line Protection Card – 1+1 / 1:1

Description

Overview

The OLP optical protection card is to assist the wavelength division system to complete optical layer protection solutions such as optical line 1+1/1:1 protection and optical wavelength 1+1/1:1 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 to recover quickly. OLP technology is to complete the routing switch operation in optical layer.

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

Deployment Scenarios

• Optical line 1+1 protection between two sites that have diverse fiber routes
• Optical wavelength 1+1/1:1 protection inside a wavelength division system
• Links where a blocked or degraded fiber core must be bypassed automatically
• Networks that need the routing switch completed in the optical layer rather than in upper services
• Sites that require uninterrupted communication with real-time optical power monitoring
