SFP-H10GB-ACU10M=

The SFP-H10GB-ACU10M is an active twinax copper cable, 10 m long, with an SFP+ connector fixed to each end. Cisco's data sheet lists the conductor as 28 AWG at this length. Seat each plug until it latches, then give the cable a gentle tug to confirm the pull-tab latch has engaged. Neat hook-and-loop strapping helps keep front-to-back airflow clear around the switch faceplate. Use it when equipment is a few cabinets apart and a shorter cable would be pulled tight. It is intended for data-centre environments and has a standard commercial temperature range. Handle it by the connector bodies, keep the bend radius generous, and avoid tight ties that squeeze the jacket. It contains signal-conditioning electronics, which keep the electrical link clean over a longer copper run than the passive range allows. It joins two 10 Gigabit Ethernet SFP+ ports directly, with no separate modules needed.
