50G optics (Optical transceivers) options
Posted by Admin on 2022 Dec 16th
50G transceiver modules
are available in the SFP56 and QSFP28 form factors. The differences are
the electrical signal and size.
A 50G QSFP28 uses 2 of
the 4 available electrical lanes (Electrical I/O) on a QSFP connector,
with each lane running at 25Gbs NRZ. A 50G SFP56 uses 1 x 50Gbs PAM-4
lane (26.5625Gbaud/s).
Both use PAM4 modulation for the optical signal.
The SFP56 module is
slightly smaller in size than a QSFP28 and allows for hi
