OADM BU

I noticed that several times, Pipe guys have addressed this "OADM BU" issue installed in their PPC-1 system. What is special in it ? How reliable is this kind of BU ? How much budget can we save compared to "normal BU" deployment ? ... Any idea ?!?



At functionality level, I see this OADM BU as simple as "OADM+BU" which is put underwater. It could especially be useful, when we need to "pull & push" a relatively small capacity compared to the whole fiber capacity and for some reasons we do not want to route "pass-thru" traffic via the corresponding points. With this in mind, such equipment are suitable only for submarine repeatered cable systems. Agree ? :-D Comments are welcome ...
