12-Fiber LGX Adapter Panel, 12 Simplex ST/UPC Single-Mode (FAP-SM-ST-12S)

This is a 12-fiber LGX adapter panel loaded with twelve simplex ST/UPC single-mode adapters, with dust caps for the unused ports. It's a 1.6 mm cold-rolled steel plate, 130 by 30 mm, which is the single-width LGX footprint, with the twelve bayonet couplers packed across it in two rows. The ST connectors on the pigtails twist onto the back and the patch cords twist onto the front, so one plate turns a spliced 12-fiber single-mode cable into 12 ST ports, which is six duplex links, in the same slot the 6-port ST plate uses for three. It's the plate for an older single-mode plant that is still on ST, isn't being converted, and has more fibers than slots. It drops into any LGX slot: the RMFP rack-mount splice-and-patch panels, the RMFP-001 patch-only panel, and any other LGX enclosure. It's sold individually. For 6 ST ports with more room between them, the FAP-SM-ST-6S; for 12 single-mode fibers on LC in the same slot, the FAP-SM-LCU-6DF; for the ST pigtails that twist onto the back, the PGTST12-SM; for the cords on the front, the STSTSM, and for ST to an LC switch port, the LCSTSM; for the enclosures, the RMFP-015, RMFP-016, RMFP-018, and RMFP-001.

Features

• Twelve simplex ST/UPC adapters, 12 fibers. Single-mode, bayonet couplers, dust caps included.
• Twice the ST density. 12 ST ports in one single-width LGX slot.
• LGX footprint. 130 × 30 mm single-width plate; fits standard LGX panels and enclosures in a 19 in rack.
• Cold-rolled steel, 1.6 mm.
• Clip-in adapters. Each coupler can be replaced without changing the plate.
• Sold individually.

Where It Fits

It suits a campus or a utility site where a 12-fiber single-mode backbone was terminated on ST years ago and the whole cable has to come out on one LGX plate, because the enclosure is short on slots. It suits a telecom room or a carrier handoff where an old ST plant is being tidied into a rack-mount panel without re-terminating to LC. Installers filling an RMFP panel on an all-ST single-mode plant use it, and so do techs replacing two 6-port ST plates with one to free a slot. A rack that still has a dozen single-mode ST patch cords in it is a candidate. It goes with the single-mode bulk fiber, the ST pigtails, the splice trays, and the ST patch cords from the fiber collections, and with the LGX enclosures from the fiber panel collection. For a 1U splice-and-patch panel, the RMFP-015. For 2U, the RMFP-016, and for 4U, the RMFP-018. For a patch-only 1U, the RMFP-001. For 6 ST ports with more finger room, the FAP-SM-ST-6S. For 12 single-mode fibers on LC in the same slot, the FAP-SM-LCU-6DF, or 24 on the quad FAP-SM-LCU-6Q. For the pigtails, the PGTST12-SM. For the cords, the STSTSM, and for ST to LC gear, the LCSTSM.

Good to Know

Match the fiber on both sides: this is the single-mode plate, and for a multimode ST plant the FAP-MM-ST-6S is the one to order, since the plates look alike on the rack. UPC is the flat-polish, and single-mode ST is UPC in practice, with no APC version of ST in general use, so the whole channel is UPC. Twelve ST couplers in 130 mm is tight: ST is a bayonet that needs a quarter turn to lock, and with the neighbors this close there's little room to get a grip, so plan on cords with a slim boot, work from the outside ports inward, and expect to unplug a neighbor to reach a port in the middle; if the slot count allows, the 6-port FAP-SM-ST-6S is the easier plate to live with. Push each cord on, turn it until it locks, and tug gently to confirm it seated, since a half-locked ST reads as a high-loss link. The ports are simplex, so a transmit-and-receive pair is two adjacent ports; label which is which, because ST has no duplex clip to keep polarity for you, and with 12 ports a port map inside the door is worth the minute it takes. If the switches have moved to LC and the ST gear is on its way out, the FAP-SM-LCU-6DF with LC-to-ST cords to the old equipment is the plate to buy instead, since it holds the same 12 fibers with room to spare. Check the LGX slot before you order: 130 by 30 mm is the standard single-width cutout, so the plate fits enclosures built to that pattern, and any slot left empty takes the FAP-BLANK blanking plate. Twist all 12 pigtails onto the back before you mount the plate, since there's no room to do it in the slot, and leave the dust caps on any port without a cord in it; a 9 µm core is far less forgiving of a speck of dust than a multimode one. Clean and inspect every ferrule before it goes into an adapter, and label the plate's ports by fiber number so the tray and the panel agree.
