I’m in the process of doing a very large hardware refresh for my company. We’re replacing 100+ old/EOL switches throughout the network/country. This shouldn’t be too big of a deal, but the latest generation of Cisco switches use SFPs. The older stuff is all GBIC. For most of our large sites, this isn’t major as we just run an ST to LC cable from the patch panel to the switch…

But of course, there are random sites without patch panels. The fiber runs directly from switch to switch. This presents a problem as we don’t have detailed information for most of our sites. So the options are re-terminating the ends of the fiber, buying a long enough patch cable (difficult to do) or having someone come out and pull new runs. That was until I came across these:

Tripp Lite N458-001-50 Duplex Multimode 50/125 Fiber Adapter, LC-M/SC-F – 1ft

These SC to LC adapters are a godsend. I wasn’t aware of their existence until last week. Not sure if they’re widely used and I’ve been living under a rock or what. We’re ordering a ton of these and will be shipping them out with the replacement switches, just in case.

Not a very meaty or informative post, but I’m thinking others may not know about these little adapters either. Hopefully some of you find this useful.
