Ekivalan OM4 Duplex Fibre Patch Cable LC to ST, 50/125 µm, Heather Violet, 15 m COZOM4LCST2SE0150A

Data centre technicians and network engineers often need a reliable multimode fibre link between LC and ST ports. The Ekivalan OM4 duplex patch cable bridges that gap with a 15-metre run of laser-optimised 50/125 µm fibre, terminated with an LC connector on one end and an ST connector on the other. The heather violet LSZH jacket keeps the cable identifiable and safe for indoor runs.

Why choose it

OM4 fibre supports high-speed Ethernet standards, making this cable suitable for 10G, 40G, and 100G connections over short to medium distances. The duplex design provides two fibres in one jacket for bidirectional communication. LSZH jacketing reduces smoke and toxic emissions in the event of fire, a key requirement for enclosed spaces.

Ideal use cases

• Connecting switches or patch panels with LC ports to legacy equipment with ST ports
• High-density data centre interconnects
• Enterprise backbone links up to 150 m at 40/100 GbE

Good to know

The cable meets TIA/EIA-568-C.3, ISO/IEC 11801, and EN 50173-1 standards for structured cabling. The ST connector uses a bayonet-style coupling for secure mating, while the LC connector offers a compact latch for high-density patching.
