LC to SC Duplex Fiber Optic Patch Cable - Multimode OM1 62.5/125μm

A lot of 62.5 µm fiber backbones were terminated on SC, the push-pull connector that replaced ST on patch panels and wall enclosures through the 2000s. The switches that connect to them now take LC SFPs. This cord joins the two, with a pair of LC connectors on one end for the SFP or LC panel and a pair of SC connectors on the other for the SC panel or port, on OM1 fiber that matches the plant. It runs 100 Mb/s Ethernet to 2 km and Gigabit to 275 m, so an existing building backbone keeps working with new electronics at one end.

It's a duplex zipcord, two 62.5/125 µm fibers in a 1.8 × 3.7 mm jacket. Each cord is tested and the end-faces are checked by interferometer before it ships.

Features

• LC to SC. Snap-in LC on one end, push-pull SC on the other, both with PC-polished ferrules.
• OM1 multimode, 62.5/125 µm. Matches the 62.5 µm fiber in older building backbones; 100BASE-FX to 2 km and 1000BASE-SX to 275 m.
• Duplex zipcord. Two fibers in one jacket, wired A-to-B, for a matched transmit and receive pair.
• Low insertion loss. 0.25 dB typical and 0.30 dB maximum per connector.
• 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.
• Orange PVC jacket, 1.8 × 3.7 mm. Standard duplex zipcord in the OM1 color; fits any LC or SC panel and cable manager.
• UL Listed for the US and Canada, and RoHS compliant.
• Fourteen lengths from 1 to 30 m.

Where It Fits

It suits connecting a new switch or SFP to an existing SC patch panel on a 62.5 µm backbone, linking a media converter or older switch with SC ports to LC equipment, 100 Mb/s and Gigabit uplinks between floors or buildings on OM1 fiber where only the electronics have been replaced, and any multimode link between an LC port and an SC port on a 62.5 µm plant.

Good to Know

Match the fiber, not just the connectors. OM1 is 62.5 µm core; OM2, OM3, and OM4 are 50 µm. Putting a 62.5 µm cord in front of a 50 µm fiber loses several dB at the junction because most of the light lands outside the smaller core, so use this cord only on a plant that's 62.5 µm end to end, which is usually the orange cable and the older install. If your backbone is aqua OM3 or OM4, you want a 50 µm LC to SC cord. On the SFP side, use a multimode SX or SR module; a single-mode LX module will light an OM1 link only over short distances and with a mode-conditioning 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. If the panel is ST rather than SC, look at the LC to ST OM1 cord.
