SFP-H25G-CU2.5M=

The SFP-H25G-CU2.5M is a passive copper cable for 25 Gigabit Ethernet, 2.5 m long, with an SFP28 connector on each end. As a pre-terminated unit, it removes the need to match, stock or clean separate pluggable modules at either end. It joins SFP28 ports directly, can carry FCoE with suitable host software, and has no active parts or diagnostics. Both connector ends use the same housing style, so the cable has no preferred direction when installed. Hot-swap behaviour follows the host port, and the link normally comes up once both ends are seated. The host port must use BASE-R (FC-FEC) forward error correction at this length. Cisco's 25GBASE SFP28 data sheet lists it as a 25GBASE-CR1 direct-attach cable. Plan the route before ordering, because a fixed-length cable cannot be shortened or extended later. This length covers links within one rack, and reaches the next cabinet when the two racks stand side by side.
