LC to LC Switchable Uniboot Fiber Cable - Single Mode OS2 9/125μm Duplex

Closeout, final sale. This cord is being discontinued and won't be restocked; only the lengths still shown are available. Orders can't be cancelled once placed, and the cord isn't eligible for return, exchange, or refund. Please read the specifications below carefully before you order, and get in touch first if you have any questions.

This is a uniboot LC cord, both fibers in one round 2.0 mm jacket with a single boot at each end, with one extra trick: the polarity can be flipped in the field. On a standard duplex cord, if transmit lands on transmit at the far end, you have to pull the cord and swap it for one wired the other way, or put a crossover adapter in the path. On this cord you separate the two connector halves at the boot, swap their positions, and clip them back together, in a few seconds and without tools. In a rack where the panels were wired by someone else and the labels are long gone, that's a real time saver.

It's OS2 single-mode fiber, 9/125 µm, with LC/UPC connectors on both ends and extended push-pull tabs so the cord can be pulled from a dense line card without a fingernail on the latch. Each cord is tested and the end-faces are checked by interferometer before it ships.

Features

• Reversible polarity. Swap the transmit and receive positions at either end in seconds, without tools or adapters.
• Uniboot design. Two fibers in a single 2.0 mm round jacket with one boot per end, for the smallest footprint a duplex LC cord can have.
• Extended push-pull tabs. Insert and release from behind the connector, so it comes out of a crowded switch face cleanly.
• OS2 single-mode, 9/125 µm. For 1310 and 1550 nm links, from a patch panel jumper to a campus or metro span.
• LC/UPC on both ends. Blue flat-polished connectors for the UPC ports on switches, SFP and SFP+ transceivers, and patch panels.
• Low insertion loss. 0.15 dB typical and 0.30 dB maximum per connector.
• 1.25 mm ceramic ferrules, checked by 3D interferometry for end-face geometry.
• Yellow PVC jacket, 2.0 mm round. Fits any LC patch panel and cable manager, and bundles neatly.
• UL Listed for the US and Canada, and RoHS compliant.

Where It Fits

It suits high-density switch line cards and patch panels where a standard zipcord won't fit cleanly, top-of-rack to spine and leaf links, blade chassis and SAN connections, cross-connects in a fiber distribution frame where the far-end polarity isn't known until the link comes up, cold-aisle racks where airflow across the switch face matters, and any single-mode link between two UPC ports where a smaller cord and a quick polarity fix make the rack easier to manage.

Good to Know

Both ends are UPC, so both of your ports need to be UPC, which is the blue connector on almost all switches, transceivers, and patch panels. If one end of the link is a green APC port, you want an LC/UPC to LC/APC cord instead. To reverse polarity, pull the connector out of the port first, then separate and swap the two halves at the boot; never do it in the port. 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; a fingerprint on a single-mode ferrule costs more than the whole cord's loss budget. The round jacket is easy on bend radius, but keep it above about 30 mm under load and don't cinch ties down tight on it. If you need a length that isn't listed, the standard uniboot cord and the LC to LC duplex cord cover 1 to 100 m.
