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

This is the LC to LC cord for a 62.5 µm fiber plant: the switch-to-panel, panel-to-panel, and SFP-to-SFP jumper for buildings whose backbone is OM1, the original multimode fiber. The connectors are current, the fiber matches what's in the ceiling, and it runs 100 Mb/s Ethernet to 2 km and Gigabit to 275 m, which covers a building backbone or a link to the next building.

It's a duplex zipcord, two 62.5/125 µm fibers in a 1.8 × 3.8 mm jacket, 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 on both ends. Snap-in connectors with PC-polished ferrules, the standard multimode finish, for SFP transceivers, switches, and LC patch panels.
• 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.
• 1.25 mm ceramic ferrules, checked by 3D interferometry for end-face geometry.
• Orange PVC jacket, 1.8 × 3.8 mm. Standard duplex zipcord in the OM1 color; fits any LC panel and cable manager.
• UL Listed for the US and Canada, and RoHS compliant.
• Twenty lengths from 1 to 100 m.

Where It Fits

It suits switch-to-patch-panel and panel-to-panel jumpers on a 62.5 µm backbone, SFP transceiver links between switches, routers, and firewalls on OM1 fiber, 100 Mb/s and Gigabit uplinks between floors or buildings where the fiber is OM1 and only the electronics have been replaced, and any multimode link between two LC ports on a 62.5 µm plant, from a short rack jumper to a 100 m run.

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. If your backbone is aqua OM3 or OM4, or you're building a new 10 Gigabit link, you want a 50 µm LC to LC cord instead; Gigabit over OM1 tops out at 275 m and 10 Gigabit at about 33 m. Use multimode SX or SR transceivers; 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 1.25 mm one-click cleaner before mating. If the panel end is SC or ST rather than LC, look at the LC to SC or LC to ST OM1 cord.
