SC and LC are the two connectors you meet most in a single-mode network, and they don't plug into each other. SC is the larger push-pull connector on media converters, wall-mount enclosures, older switches, and a great many patch panels; LC is the small snap-in connector on SFP transceivers, new switches, and high-density panels. This cord has a pair of LC/UPC connectors on one end and a pair of SC/UPC on the other, so an SFP or LC panel can connect straight to an SC port or panel without a hybrid adapter in the middle.
It's OS2 single-mode fiber, 9/125 µm, in a duplex configuration for a transmit and receive pair, in lengths from 1 m to 100 m. Each cord is tested and the end-faces are checked by interferometer before it ships.
Features
- LC/UPC to SC/UPC. Snap-in LC on one end, push-pull SC on the other, both blue flat-polished UPC.
- OS2 single-mode, 9/125 µm. For 1310 and 1550 nm links, from a rack jumper to a campus or metro span.
- Duplex. Two fibers for a matched transmit and receive pair, wired A-to-B.
- Low insertion loss. 0.15 dB typical and 0.30 dB maximum per connector.
- Return loss 50 dB or better, the standard UPC figure.
- Ceramic ferrules, 1.25 mm on the LC end and 2.5 mm on the SC end, checked by 3D interferometry for end-face geometry.
- Tool-free on both ends. The LC latches, the SC pushes in and pulls out; neither needs a twist.
- UL Listed for the US and Canada, and RoHS compliant.
- Eighteen lengths from 1 to 100 m.
Where It Fits
It suits connecting an SFP-equipped switch or router to an SC patch panel or enclosure, linking a media converter or older switch with SC ports to LC equipment, building-to-building links terminated on SC at one end and LC at the other, data center and campus cross-connects between mixed panel types, and any single-mode link between a blue LC port and a blue SC port, from a short rack jumper to a 100 m run across a building.
Good to Know
Both ends are UPC, so both of your ports need to be blue. If the SC side is a green SC/APC port, on an FTTH outlet, ONT, or PON gear for example, you want the LC/UPC to SC/APC cord instead, and if both ends are LC, the LC/UPC to LC/UPC cord. Keep dust caps on until the moment you plug in, and clean both the connector and the port with a one-click cleaner before mating, 1.25 mm for the LC end and 2.5 mm for the SC end; a fingerprint on a single-mode ferrule costs more than the whole cord's loss budget. Single-mode fiber doesn't care about length at these distances, so pick the length that fits with a little slack and no coil. For the longer lengths, keep the cord in a tray or off the floor, and if it has to be pulled through conduit, ask about a 3.0 mm jacket or an OFNR-rated cable.
