SFP-H10GB-CU2M=

The SFP-H10GB-CU2M is a passive twinax copper cable, 2 m long, with an SFP+ connector permanently attached at each end. Because it is built to a set length, stock planning is by length, so a rack plan listing each link helps ordering. Cisco lists this length on 30 AWG twinax, a thinner and more flexible conductor. Neighbouring cabinets in a row are the usual target, with the switch in one rack and its connected hosts in that one or the next. With no active electronics it draws very little power, about 0.1 W per the data sheet, and reports no digital diagnostics. Hot-swap behaviour follows the host port, and the link normally comes up once both ends are seated. The cable is a single sealed assembly, supplied as the spare part number with the equals suffix. It carries a 10 Gigabit Ethernet link between two SFP+ ports and needs no separate transceivers. Route it clear of power cords and fan exhaust where possible, to keep the cable run tidy and serviceable.
