Protecting LC sockets on unused synchronization modules
Protect the LC sockets when storing unused synchronization modules:
Close off the LC sockets with the blanking plugs to protect them from dirt. The
synchronization modules come with blanking plugs inserted.
Reduced optical performance due to dirt
Even a small amount of dirt in the LC socket can affect the quality of the signal transmission.
Dirt can lead to synchronization losses in operation.
Protect the LC sockets from contamination during storage and installation of the
synchronization modules.
