24-Fiber LC Quad LGX Adapter Panel, Multimode OM1–OM4 (FAP-MM-LC-6Q)

This is a 24-fiber LGX adapter panel loaded with six clip-in quad LC multimode adapters, for any multimode grade from OM1 to OM4. It's a cold-rolled steel plate, 130 by 30 mm, which is the single-width LGX footprint, with the six quad couplers mounted horizontally through it on their plastic flanges, so one slot carries 24 LC ports instead of the 12 a duplex plate gives. Each adapter has phosphor bronze alignment sleeves and a PC polish, and the LC connectors on the pigtails plug into the back while the patch cords plug into the front, so one plate turns two spliced 12-fiber multimode cables, or one 24-fiber trunk, into 24 LC ports. It's the general multimode quad plate, for a 62.5 µm OM1 plant or a 50 µm one that isn't being held to a 10 Gigabit spec, at the highest LC count a single slot holds: 72 LC in a 1U RMFP panel, 144 in the 2U, 288 in the 4U. 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 12 fibers in a slot, the beige duplex FAP-MM-LC-6DF; for an OM3 or OM4 plant held to 10 Gigabit, the aqua quad FAP-MM-LCG-6Q; for the single-mode quad, the FAP-SM-LCU-6Q; for the 12-fiber LC pigtails that plug into the back, the PGTLC12-OM1, PGULC12-OM3, and PGTLC12-OM3; for the cords on the front, the LCLCOM1 and LCLCOM3; for the enclosures, the RMFP-015, RMFP-016, RMFP-018, and RMFP-001.

Features

• Six quad LC adapters, 24 fibers. Multimode OM1 through OM4, phosphor bronze alignment sleeves, PC polish.
• Twice the density of a duplex plate. 24 LC ports in one single-width LGX slot.
• LGX footprint. 130 × 30 mm single-width plate; fits standard LGX panels and enclosures.
• Cold-rolled steel.
• Horizontal clip-in couplers on flanges. Each adapter clips through the plate on its own plastic flanges.
• Sold individually.

Where It Fits

It suits a campus or a building backbone on 62.5 µm OM1 or older 50 µm multimode where rack units are scarce and a 24-fiber trunk has to come out on LC in one slot, so a 1U panel carries 72 fibers and a 4U carries 288. It suits a telecom room that is moving an OM1 plant from SC or ST to LC switches without changing the fiber, and wants the old 24-fiber cable on one plate instead of two. Installers filling an RMFP panel to its rated capacity on a Gigabit multimode plant use it, and so do techs swapping a duplex plate for a quad to double a slot without touching the rest of the panel. A hospital or a school consolidating several OM1 trunks into one rack-mount enclosure is a candidate. It goes with the multimode bulk fiber, the LC pigtails, the splice trays, and the LC 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, with three of these for 72 LC. For 2U, the RMFP-016, with six for 144, and for 4U, the RMFP-018, with twelve for 288. For a patch-only 1U, the RMFP-001. For 12 fibers in a slot, the beige FAP-MM-LC-6DF. For an OM3 or OM4 plant held to 10 Gigabit, the aqua quad FAP-MM-LCG-6Q. For single-mode, the quad FAP-SM-LCU-6Q. For multimode on SC, the FAP-MM-SC-6D or FAP-MM-SC-6S, and on ST, the FAP-MM-ST-6S or FAP-MM-ST-12S. For the pigtails, the PGTLC12-OM1 on OM1 and the PGULC12-OM3 or PGTLC12-OM3 on OM3. For the cords, the LCLCOM1 and LCLCOM3.

Good to Know

Match the fiber on both sides: the plate takes any multimode grade, which means the adapters will happily mate an orange 62.5 µm OM1 cord to an aqua 50 µm OM3 pigtail, 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 be the cue. For an OM3 or OM4 plant that has to meet a 10 Gigabit spec, the aqua FAP-MM-LCG-6Q is the quad the as-built should show, since its color says what's behind it; this one is the right choice for OM1 and for a Gigabit plant on any grade. The sleeves are phosphor bronze, which is the usual multimode sleeve; for single-mode, the FAP-SM-LCU-6Q with its ceramic sleeves is the right quad. A quad plate is dense: 24 LC connectors in 130 mm leaves little room for fingers, so plan the cord dressing before you load it, use cords with a pull tab or a flexible boot, and expect to unplug a neighbor to reach a port in the middle. Plug all 24 pigtails into the back before you mount the plate, since there's no room to do it in the slot, and keep every adapter's dust caps in until a cord goes in. Keep the A and B fibers of each duplex pair in the right positions on the back so the front polarity comes out as the as-built says; with 24 ports, a port map taped inside the door is worth the minute it takes. 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-CP24-A8 and CCH-CP24-D3, so it fits enclosures built to that pattern; any slot left empty takes the FAP-BLANK blanking plate. The adapters are horizontal, so the duplex cords lie side by side across the slot and the panel's cable management has to clear them to the left and right. Clean and inspect every connector before it goes into an adapter, and label the plate's ports by fiber number so the tray and the panel agree.
