Our take on the Compaq 221691-B21 2M OM3 LC-SC Fiber Optic Channel Cable Kit

The Compaq 221691-B21 is a 2-meter OM3 multimode fiber optic cable with an LC connector on one end and an SC connector on the other. It is a crossover-style patch cable for linking switches, HBAs and storage arrays in short data center runs. OM3 glass supports 10 Gb Ethernet and 8/16 Gb Fibre Channel over these distances. It suits admins cabling racks and adjacent cabinets where the two port types differ; generic OM3 LC-SC patch cords do the same job, so buy on connector quality and length fit.

Questions and answers

What is this cable used for?
It links two fiber devices over a short run, with an LC connector on one end and an SC connector on the other. Typical uses are switch-to-server and switch-to-storage links in a rack.
Does it support 10 Gb Ethernet?
Yes. OM3 multimode glass is rated for 10 Gb Ethernet over these short distances. It also handles 8 Gb and 16 Gb Fibre Channel links.
Is it OM3 or OM4?
It is OM3 multimode fiber. OM3 works for most in-rack links; OM4 gives longer reach at the highest speeds.
Can I use it between an LC port and an SC port?
Yes. That mixed pairing is the point of this cable. Check that each device's transceiver matches the connector on its end.
What is in the kit?
The kit is the 2-meter LC-SC OM3 cable. It is a single cable, so a duplex link needs two.
Where is the Compaq 221691-B21 2M OM3 LC-SC Fiber Optic Channel Cable Kit cheapest?
At Gotodirect, for $169.82, as of our latest check.
