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

SC took over from ST as the connector on multimode patch panels and wall enclosures through the 2000s, and a lot of 62.5 µm building backbones were terminated on it. This cord has a pair of SC push-pull connectors on each end, on OM1 fiber that matches that plant, for patching between SC panels or from an SC panel to an SC port on a media converter, older switch, or instrument. It runs 100 Mb/s Ethernet to 2 km and Gigabit to 275 m, which is more than enough for a building backbone.

It's a duplex zipcord, two 62.5/125 µm fibers in a 3.0 mm jacket. Each cord is tested and the end-faces are checked by interferometer before it ships.

Features

• SC on both ends. Push-pull connectors with PC-polished ferrules, the standard multimode finish.
• 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. 0.20 dB typical and 0.30 dB maximum per connector.
• 2.5 mm ceramic ferrules, checked by 3D interferometry for end-face geometry.
• Push-pull housings. Square latch that seats positively and releases without tools.
• Orange PVC jacket, 3.0 × 6.1 mm. Heavier 3.0 mm zipcord in the OM1 color, for equipment rooms and trays.
• UL Listed for the US and Canada, and RoHS compliant.
• Twelve lengths from 1 to 30 m.

Where It Fits

It suits jumpers between SC patch panels and enclosures on a 62.5 µm backbone, links from an SC panel to media converters, older switches, and routers with SC ports, 100 Mb/s and Gigabit uplinks between floors or buildings on existing OM1 fiber, and any multimode link between two SC ports 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 SC to SC cord. Keep dust caps on until the moment you plug in, and clean both the connector and the port with a 2.5 mm one-click cleaner before mating. If the equipment side is LC rather than SC, look at the LC to SC OM1 cord, and if the far end is ST, the SC to ST OM1 cord. Gigabit over OM1 tops out at 275 m and 10 Gigabit at about 33 m, so if you're planning an upgrade, the fiber, not the cord, is the limit.
