12-Fiber LGX Adapter Panel, 12 Simplex ST Multimode (FAP-MM-ST-12S)

This is a 12-fiber LGX adapter panel loaded with twelve simplex ST multimode 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 multimode 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 multimode 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-MM-ST-6S; for the single-mode version, the FAP-SM-ST-12S; for 12 multimode fibers on LC in the same slot, the beige FAP-MM-LC-6DF; for the ST pigtails that twist onto the back, the PGTST12-OM1; for the cords on the front, the STSTOM1 and STSTOM3, and for ST to an LC switch port, the LCSTOM1 and LCSTOM3; for the enclosures, the RMFP-015, RMFP-016, RMFP-018, and RMFP-001.

Features

• Twelve simplex ST adapters, 12 fibers. Multimode, 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 plant where a 12-fiber multimode 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 where an old OM1 or OM3 ST plant is being tidied into a rack-mount panel without re-terminating to LC. Installers filling an RMFP panel on an all-ST multimode 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 multimode ST patch cords in it is a candidate. It goes with the multimode 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-MM-ST-6S. For a single-mode ST plant, the FAP-SM-ST-12S. For 12 multimode fibers on LC in the same slot, the beige FAP-MM-LC-6DF, or the aqua FAP-MM-LCG-6DF for 10 Gigabit. For the pigtails, the PGTST12-OM1. For the cords, the STSTOM1 on a 62.5 µm plant and the STSTOM3 on OM3, and for ST to LC gear, the LCSTOM1 and LCSTOM3.

Good to Know

Match the fiber on both sides: the page rates this plate for multimode without naming a grade, and an ST coupler will mate a 62.5 µm OM1 cord to a 50 µm OM3 pigtail without complaint, with the core mismatch loss landing at the panel; keep the pigtails, the cords, and the plant all one grade, and let the jacket color (orange for OM1, aqua for OM3 and OM4) be the cue. For single-mode on ST, the FAP-SM-ST-12S is the one to order, since the plates look alike on the rack. 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-MM-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 beige FAP-MM-LC-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, and this plate is the same footprint as the Corning CCH-CP12-15T and CCH-CP12-G5, so it fits enclosures built to that pattern; 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. 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.
