RUS 01 B3¶
Front-Haul interface (CPRI)¶
These look like SFP connectors, but are not. They are of a special connector type, but have the same electrical signaling.
We presume Ericsson did this so you cannot easily use a RUS remotely by plugging in a SFP transceiver for fiber optic transmission.
Instead, you have to use special copper CPRI cables from Ericsson: RPM 777 211/xxxxx where xxxxx is the length in mm.
