1:1 NET-Ready Optical Protection
Switch
A (1:1) optical protection system provides two diverse routes for the same link. On
detection of a failure, the receiver end signals the transmitter end via a signaling
channel. First the transmitter end and then the receiver end switch onto the
protection connection. The (1:1) NET-Ready protection switch in 1x2 or 2x2
switch configurations provide this type of protection. The same switch fits both
point-to-point and shared protection switching ring architectures.
NET-Ready (1:1) protection switch provides both Manual and Automatic switching
mode. In Manual mode, the system switches optical path only based on the
commands from user. In the Automatic mode, the system switches based on the
power level detected and the pre-set threshold. Under automatic mode, the system
can be set to be Revertive or Non-revertive modes. Under Revertive mode, the
system switches back to the working path automatically after the fault condition is
cleared. Under Non-revertive mode, the system does not switch back.
Alarm and switching threshold and hysteresis are programmable remotely or locally.
