4.4 Interfaces
The Ethernet expansion provides the following interfaces in the XMP1
system:
Ethernet interfaces
The SCU-BETH board provides four Fast Ethernet interfaces. These can be
equipped with electrical and optical SFPs and any combination of both.
Optical STM-1/4 interfaces
The optical SDH interfaces are provided by SFPs. These SFPs can be
supplied with 1300 nm and 1550 nm optics.
Connection is implemented using LC-type plug connectors.
