QSFP-H40G-AOC10M=

The QSFP-H40G-AOC10M is a 40 Gigabit active optical cable, 10 m long, with a QSFP+ connector on each end and multimode fibre carrying four lanes between them. The rate is fixed by the cable type, so the port at each end must be set for the matching speed. Both ends are permanently attached, so nothing needs cleaning, and the whole cable is replaced if either end is damaged. The fibre jacket is lighter and thinner than 40G copper and avoids the reach limits copper has at this speed. The optics are sealed into the connector bodies, so there are no MPO connectors to clean and no transceivers to match. The extra length makes it practical for links between racks in a row, including paths through overhead trays or floor routing. Neat hook-and-loop strapping helps keep front-to-back airflow clear around the switch faceplate. Keep a spare of the same length on the shelf if the link is critical, as there is no field repair for a moulded cable. Cisco's 40GBASE QSFP data sheet lists it among the QSFP-to-QSFP active optical cables, available from 1 m to 30 m.
