Intellinet OM3 LC/UPC to LC/UPC Duplex Multimode Fibre Optic Patch Cord, 3m, LSZH, Aqua

The Intellinet 750066 is a 3 m duplex multimode fibre optic patch cord (50/125 µm, OM3) with LC/UPC connectors at both ends, for connecting switches, transceivers, patch panels and servers and storage in multimode installations.

OM3 is the laser-optimised multimode grade for 10G short reach: IEEE 802.3 specifies 10GBASE-SR for up to 300 m on OM3 (and 40G/100G SR4 for up to 100 m), so at patch-cord length the fibre is never the bottleneck.

• 1 × Intellinet OM3 LC/UPC to LC/UPC duplex fibre patch cord, 3 m
• Supplied in a bag (polybag)

• LC — the small-form-factor latch connector used on SFP, SFP+, SFP28 and QSFP transceivers and on most current switches and patch panels
• Duplex means two fibres in one cord — one transmits, one receives — the normal format for a switch-to-switch, switch-to-server or switch-to-patch-panel link.
• At 3 m it suits patching within a rack or to the next rack in the same row.
• LSZH jacket, 3.0 mm outer diameter: low smoke and zero halogen if it ever burns, which is what most offices, server rooms and public buildings ask for indoors.
• If a new duplex link stays down, the most common cause is crossed transmit/receive — swap the two fibres at one end and test again. Also check that both transceivers are the same type and wavelength.

• Singlemode transceivers (LR, LX, ER, BiDi singlemode) and OS1/OS2 singlemode cabling — multimode and singlemode fibre cannot be mixed on one link.
• Legacy 62.5/125 µm (OM1) cabling — the core size differs, so mixing it with this 50/125 µm cord adds large loss.
• Ports with a different connector: this cord needs LC ports at both ends. For any other combination choose a different cord rather than adding adapters to the link.
• Copper RJ45 ports — a fibre cord needs an optical port, an SFP/SFP+ transceiver or a media converter at each end.
