SC Simplex Multimode Fiber Keystone Jack, White (KEYSCMM-WHI)

This is a simplex SC keystone jack for multimode fiber, in white. It's a snap-in keystone insert with an SC coupler in it: the SC connector on the horizontal fiber pushes into the back, the SC patch cord pushes into the front, and the plate or panel looks like every other keystone outlet. It's one fiber per jack, so a duplex link takes two of them side by side. It takes 50/125 µm OM2, OM3, and OM4 and 62.5/125 µm OM1, with a typical insertion loss under 0.3 dB. The housing is UL 94 V-0 PBT with a phosphor bronze sleeve and a stainless steel clip, rated for 500 matings and 10 kgf of pull, and it comes with a dust cap. It snaps into a keystone opening in a wall plate, a surface-mount box, or a blank keystone panel. It's sold individually. For the single-mode version, the KEYSCSM-WHI; for the SC multimode cords that plug into it, the SCSCOM1, SCSCOM3, and LCSCOM3; for a duplex LC jack instead, the KEYLCMM-WHI.

Where It Fits

It suits a campus or a building backbone where the multimode links between closets land on SC and a pair has to come out at a wall plate or a keystone panel beside the copper. It suits a classroom, a lab, or an equipment room where an older OM1 or OM3 plant on SC is being brought to a keystone outlet without re-terminating to LC. Installers who terminate multimode at a keystone plate rather than a fiber enclosure use it, and so do techs adding one SC fiber outlet at a desk, a media converter, or a camera position. A blank keystone panel in a small closet that mixes a pair of SC multimode ports with the copper is a candidate. It goes with the multimode bulk fiber, the SC connectors or pigtails for the horizontal side, and the SC cords from the fiber collections, and with the keystone wall plates and panels from the copper collection. For the SC-to-SC cords, the SCSCOM1 on a 62.5 µm plant and the SCSCOM3 on OM3, and for SC to an LC switch port, the LCSCOM1 and LCSCOM3. For single-mode SC, the KEYSCSM-WHI. For a duplex LC outlet instead, the KEYLCMM-WHI. For splicing a 12-fiber OM3 or OM1 cable out to SC, the PGTSC12-OM3 and PGTSC12-OM1 pigtails.

Good to Know

Match the fiber on both sides: the coupler takes 50 and 62.5 µm alike, so it will happily mate an orange OM1 cord to an aqua OM3 fiber, and the core mismatch loss lands at the plate; keep the cord color matched to the plant. For a 9/125 µm single-mode pair, the KEYSCSM-WHI is the one to order. The reach of the link is set by the fiber and the optics, not by the jack: OM3 carries Gigabit to 550 meters and 10 Gigabit to 300 meters, OM1 carries Gigabit to 275 meters, and the jack simply adds a mated pair, roughly 0.3 dB, that the loss budget has to carry along with the connectors at the far end. It's simplex, so a transmit-and-receive pair is two jacks; put them side by side and label which is which, because a simplex SC has no duplex clip to keep polarity for you. The page doesn't name a polish, and multimode SC is UPC or PC in practice; there's no APC version of multimode in general use. Clean and inspect both the cord's ferrule and the ferrule behind the plate before mating, and keep the dust cap in any jack without a cord in it. The fiber behind the plate needs room to bend: a standard single-gang box is shallow, so use a deep box or a surface-mount box and coil the slack in a loop no tighter than the fiber's bend radius before it enters the jack. The tensile rating is 10 kgf, which is more than enough for a patch cord but not for a cable hanging on the jack, so strain-relieve the horizontal fiber in the box. An SC is wider than an LC, so a plate full of simplex SC jacks gets fewer fibers per gang than the duplex LC jack would; where port count matters, the KEYLCMM-WHI puts a pair in one opening.
