Optical Bypass Switches

Category:

Optical Bypass Switches provide protection and monitoring of optical cross-connects (OXCs), optical add-drop multiplexers (OADMs), and other systems during power outages or system failures.

These devices also make it easy to perform network maintenance.

They are available in 2×2 bidirectional and non-bidirectional configurations in a compact LGX cassette package.

A switch on the front of the cassette provides the user with the option of enabling a delay of either 0, 60 or 120 seconds before the device resumes its normal mode after a power outage. This allows other devices to fully power on before resuming network traffic.

1310nm or 1550nm wavelengths and 10/1Gbps fiber gigabit ethernet networks are supported.
