MSDH to MTDI Connections 4.4.2
To connect the MSDH to the MTDI
Connect either the MTDI SM (L1 port) or the MM (L2 port) port to the corresponding SFP + module
installed in one of the MSDH CPRI port:
x L1 SFP = Multimode SFP+ transceiver 850nm 400m 10Gb MM LC
x L2 SFP = Single Mode SFP+ transceiver 1310nm 10 km 10Gb SM LC
Recommendation for connections -
For more orderly connections and intuitive identification, it is recommended to connect the lower CPRI ports
(i.e. CPRI Ports 1, 2, 3 etc.) to MTDI units or to an additional MSDH unit if relevant. The higher or remaining
CPRI ports can then be connected to remote units.
