Your switch port's dead, the rack's half-patched, and you've got a Monday deadline. You need a fibre lead that just works — no mystery, no 'we'll test it when it gets here.' This is a 3M LC-LC OM4 multimode duplex patch lead, 3 metres, aqua jacket, 2mm oversleeving. Plug it in, light comes up. Backwards compatible with your existing OM3 runs, so you're not ripping cable out of the ceiling. LSZH jacket means it meets code for enclosed spaces and risers. Every end is UPC polished, individually inspected, and you get a factory test report in the box. Conforms to ISO/IEC 11801, ITU-T G.651, TIA/EIA-492-AAAD. Cross-connects, backbone runs, equipment-to-equipment — it handles data, voice, and video at full speed
