QSFP-100G-AOC1M=

The QSFP-100G-AOC1M is a 100 Gigabit active optical cable, 1 m long, with a QSFP28 connector at each end and multimode fibre carrying four 25G lanes between them. 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. Hot-swap behaviour follows the host port, and the link normally comes up once both ends are seated. The optics are sealed into the connector bodies, so there is no MPO fibre to clean and no module pairing to manage. Laying the cable in before the equipment is fully racked leaves the final connection for last and saves rework. Typical placement is a top-of-rack switch connecting to the server directly beneath it, with almost no excess cable to tuck away. Because it is built to a set length, stock planning is by length, so a rack plan listing each link helps ordering. The slim, flexible fibre jacket is easier to route than 100G copper and keeps working at distances where passive copper runs out. Cisco's 100GBASE QSFP-100G data sheet lists it in the active optical cable table.
