SFP-25G-AOC7M=

The SFP-25G-AOC7M is a 25 Gigabit active optical cable, 7 m long, with an SFP28 connector on each end and multimode fibre between them. Because it is built to a set length, stock planning is by length, so a rack plan listing each link helps ordering. Both ends are permanently attached, so nothing needs cleaning, and the whole cable is replaced if either end is damaged. The optics are sealed inside the connector bodies, so installation is simply plugging in both ends. Seat each plug until it latches, then give the cable a gentle tug to confirm the pull-tab latch has engaged. It suits end-of-row and adjacent-rack layouts where the route is longer than the straight-line distance between the two ports. Cisco's 25GBASE SFP28 data sheet lists it as a 25GBASE-AOC assembly and says the host may use either BASE-R or RS-FEC. The slim fibre jacket is lighter than twinax copper, which helps in crowded trays and server cabinets. As a pre-terminated unit, it removes the need to match, stock or clean separate pluggable modules at either end.
