lidkew OM1 Duplex ST-ST Fiber Patch Cable 30m

lidkew OM1 62.5/125µm duplex ST-to-ST multimode fiber patch cable — a 30m LSZH jumper built for reliable short-range Ethernet and data center links with low insertion loss.

This 98.4-foot lidkew fiber jumper pairs two 62.5/125µm OM1 multimode cores in a duplex assembly with ST/UPC connectors on both ends. Engineered for LAN, SAN, small data center runs, and telecom patching, the cable blends standard multimode performance with a safety-minded LSZH jacket and rugged internal reinforcement for frequent routing and cabinet bends. It’s designed to be plug-and-play with legacy multimode hardware while offering stable signal integrity for gigabit networking over typical short distances.

How fast and far can this OM1 ST–ST cable carry data?

The lidkew OM1 duplex cable supports standard multimode link speeds and distances for 62.5/125µm fiber. Expect 1Gbps over several hundred meters and practical 10GbE over short runs where OM1 is acceptable.

• 1Gb Ethernet: up to about 550 meters at 850 nm
• 10Gb Ethernet: practical distances around 82 meters at 850 nm
• Nominal bandwidth: 500/500 MHz·km at 850/1300 nm
• Connector polish: UPC for consistent return loss and mating

What makes construction reliable for repeated installs and tight routing?

Materials and mechanical design reduce damage during handling and tight installations. The cable balances flexibility with internal strength so it survives cabinet turns and repeated re-patching.

• LSZH outer jacket reduces toxic fumes in enclosed environments
• Aramid strength members inside protect fibers from tension
• 7.5 mm minimum bend radius enables tighter routing without signal loss
• Zirconia ceramic ferrules in ST housings preserve alignment and low loss

How compatible is this ST–ST OM1 patch cord with networking gear?

The duplex ST–ST format works with standard multimode terminations and many legacy transceivers. It’s useful where ST connectors or multimode ports remain in service.

• ST/UPC to ST/UPC duplex configuration fits ST equipment ports
• Works with multimode SFP/SFP+, media converters, fiber NICs and patch panels
• Dual-core construction supports duplex links without separate cables
• Duplex clip and embossed A/B markers simplify polarity and troubleshooting

What performance should you expect for signal quality and loss?

The lidkew OM1 jumper is manufactured to keep insertion loss low and return loss high for dependable connections in short-range multimode applications.

• Insertion loss: ≤ 0.3 dB per mated pair for low attenuation
• Return loss: ≥ 50 dB for strong back-reflection control
• UPC polish and ceramic ferrules help consistent mating performance
• Factory-tested to meet multimode optical tolerances

Who is this cable for? Installers, network technicians, and IT teams maintaining campus LANs, legacy multimode backbones, SAN cabinets, or telecom patch fields will find this lidkew 30m OM1 ST–ST duplex patch cord useful. It’s particularly suited to environments that require an orange, LSZH-sheathed multimode jumper with clear duplex identification and a robust mechanical profile for repeated reconfiguration. Choose this cable when you need a dependable short-range multimode link with legacy ST connectors, predictable loss figures, and safer low-smoke outer jacket performance.
