LC/UPC to SC/APC Fiber Patch Cable - Single Mode OS2 9/125μm Duplex

This cord bridges two worlds that don't share a connector. On one side is the SC/APC, the green push-pull connector on nearly every FTTH wall outlet, ONT, splitter, and PON port. On the other is the LC/UPC, the small blue connector on the SFP transceivers, switches, and patch panels in a network closet. They can't be plugged into each other: the housings are different sizes, and the APC's 8° angled polish and the UPC's flat polish don't mate without damage and a big loss. This cord has the right connector on each end, so a fiber drop terminated on SC/APC can land on an LC/UPC SFP without an adapter, a pigtail, or a splice.

It's OS2 single-mode fiber, 9/125 µm, in a duplex configuration for a transmit and receive pair. Each cord is tested and the end-faces are checked by interferometer before it ships.

Features

• LC/UPC to SC/APC. Blue flat-polished LC on one end, green 8° angle-polished SC on the other, for connecting high-density LC equipment to SC/APC outlets, ONTs, and PON gear.
• OS2 single-mode, 9/125 µm. For 1310 and 1550 nm links, from a patch panel 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.
• Low back reflection. The APC end's angled face sends reflections into the cladding instead of back down the fiber, which is what PON and other reflection-sensitive gear requires.
• 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.
• Snap-in LC, push-pull SC. Both latch positively and release without tools.
• UL Listed for the US and Canada, and RoHS compliant.
• Fifteen lengths from 1 to 30 m.

Where It Fits

It suits connecting an SC/APC fiber outlet or ONT to a router or switch with an LC SFP, FTTH and MDU head-end work where the distribution side is SC/APC and the active gear is LC/UPC, patching a PON OLT's SC/APC ports to an LC patch panel, cross-connecting between an APC-terminated outside plant panel and LC equipment, and any single-mode link where one end is a green SC and the other is a blue LC.

Good to Know

Match each connector to its port, not to the other end of the cord. The green SC/APC end goes into a green SC/APC port and the blue LC/UPC end into a blue LC/UPC port; forcing an APC ferrule against a UPC one leaves an air gap that costs several dB and can scratch the port. If your SC port is blue (SC/UPC), you want an LC/UPC to SC/UPC cord instead, and if both ends are LC, look at the LC/UPC to LC/APC 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, using the 2.5 mm cleaner for the SC end and the 1.25 mm for the LC end; a fingerprint on a single-mode ferrule costs more than the whole cord's loss budget. For runs longer than 30 m, or where the cord will be pulled through a tray or conduit, ask about a 3.0 mm jacket or an OFNR-rated cable.
