25G SFP28 fiber cable Max transmission distance
SFP-25G-D-AOC-10M 10 m (32.81 ft)
SFP-25G-D-AOC-20M 20 m (65.62 ft)
NOTE:
• To connect an SFP28 port on the S6850-56HF switch to a peer interface that does not support
speed and duplex autonegotiation, you must execute the speed and duplex full commands on
both interfaces. Configure the same speed and duplex mode for the two interfaces and the speed
must be the same as that of the transceiver module or cable installed in the interface.
• An SFP28 port on the LSWM124TG2H interface module does not support speed and duplex
autonegotiation. To connect an SFP28 port on the LSWM124TG2H interface module to a peer
interface, you must execute the speed and duplex full commands on both interfaces. Configure
the same speed and duplex mode for the two interfaces and the speed must be the same as that
of the transceiver module or cable installed in the interface.
