

Bi-directional (1:1) protection using bi-directional 2x2 switch



Uni-directional tap monitors designed to monitor the only the in-coming power to detect failure such as fiber cut



Designed to work for bi-directional communication using the same wavelength (duplex working) or different wave-

length (diplex working)



(1:1) point-to-point dedicated protection



1x2 optical latching switch is used as the switch to route the optical path



Photodiodes monitor the signals from both path



Signaling channel is needed to realize auto-revertive function



(1:1) point-to-point dedicated protection or O-BLSR ring protection



2x2 optical latching switch is used as the switch to route the optical path



Protection line is used for low priority traffic. Low priority traffic is interrupted during failure



Photodiodes monitor the signals from both path



External signaling channel is needed to trigger transmitter end switching and auto-reveritve function
