LC/PC Duplex Fiber Adapter, OM3/OM4 Multimode, Aqua, Ceramic Sleeve, Flanged, SC Simplex Footprint (FO4-LC-D)

This is a duplex LC/PC fiber adapter for 10 Gigabit multimode, the aqua coupler that joins two pairs of LC connectors end to end through a panel on an OM3 or OM4 plant, with the transmit and receive fibers side by side. It's a plastic housing with integrated flanges and a snap-fit body in the SC simplex footprint, so it drops into the same cutout as a simplex SC adapter and gives two LC ports in that space. Each port has a ceramic alignment sleeve, and the housing is aqua, which is the color code for laser-optimized 50/125 µm multimode, the fiber behind 10GBASE-SR, 40GBASE-SR4, and 100GBASE-SR4 links. It takes LC/PC multimode connectors. It's RoHS compliant, and it's sold individually. For four aqua LC ports in an SC duplex cutout, the quad FO4-LCP-Q; for a plate already loaded with these, the aqua FAP-MM-LCG-6DF and clip-in FAP-MM-LCG-6D with 12 ports, or the quad FAP-MM-LCG-6Q with 24; for the cords, the LCLCOM3 and LCLCOM4; for the pigtails behind the panel, the PGULC12-OM3, PGTLC12-OM3, and PGULC12-OM4; for a wall plate, the KEYLCMM-WHI LC keystone; for the beige version for OM1 or any multimode grade, the FOM-LC-D; for the aqua SC simplex in this family, the FO4-SCP-S; for single-mode, the blue FOS-LC-D.

Where It Fits

It suits a data center or a telecom room where an OM3 or OM4 backbone is spliced to LC pigtails in the tray behind a panel and the plate has SC simplex cutouts, so each one goes from one SC port to two LC ports and every port says 10 Gigabit by its color. It suits a building that is upgrading an older multimode plant to OM3 or OM4, so the new strands come out on aqua ports and the old OM1 ones stay beige. Installers loading a blank LGX plate or a fiber distribution unit port by port on a 10 Gigabit plant use it, and so do techs swapping a beige adapter for an aqua one as a panel moves to OM3. A server row or a SAN on OM4 with LC switches is a candidate. It goes with the OM3 and OM4 LC patch cords from the fiber patch cable collection, with the multimode LC pigtails, adapter plates, and keystones from the fiber panel collection, and with the rack-mount and wall-mount enclosures. For a loaded plate, the FAP-MM-LCG-6DF or FAP-MM-LCG-6D, or the quad FAP-MM-LCG-6Q. For four ports in an SC duplex cutout, the FO4-LCP-Q. For the cords, the LCLCOM3 on OM3 and the LCLCOM4 on OM4. For the pigtails, the PGULC12-OM3, PGTLC12-OM3, and PGULC12-OM4. For a wall plate, the KEYLCMM-WHI. For OM1 or a Gigabit plant on any grade, the beige FOM-LC-D. For SC on the same plant, the FO4-SCP-S. For single-mode, the FOS-LC-D.

Good to Know

Aqua is a label, not a filter: the adapter will mate whatever LC connector goes into it, including an orange 62.5 µm OM1 cord, with the core mismatch loss landing at the panel, so the color's job is to tell the next tech that the fiber behind these ports is OM3 or OM4 and the cord in front of them should be too. For an OM1 plant or a Gigabit plant on any grade, the beige FOM-LC-D is the honest choice, and beige is what an OM1 panel is expected to be. The sleeves are ceramic, which also holds a single-mode ferrule to tolerance, but a mixed panel invites a wrong patch, so keep single-mode on the blue FOS-LC-D and multimode on aqua or beige. It's PC, with a flat end-face, for the aqua or beige LC connector on every SFP+, QSFP breakout, and multimode cord; a green LC/APC connector has an 8° angle and doesn't mate with it. The adapter doesn't set the reach, the fiber does: OM3 carries 10GBASE-SR to 300 meters and OM4 to 400 meters, 40 and 100 Gigabit SR4 go 100 meters on OM3 and 150 on OM4, and each mated pair adds loss the budget has to carry, so keep the connectors clean. The snap-fit flanges are what hold it in a stamped cutout, so check that the panel takes a flanged SC simplex adapter before you order a quantity. Keep the A and B fibers in the right positions on both sides so the duplex polarity comes out as the as-built says. Clean and inspect every ferrule before it goes in, and cap any port without a cord. Don't look into an open port on a live link.
