Multimode patch cable for SAN and parallel optics

The Black Box EFN6021-002M is a 2-metre OM2 multimode patch cable with LC and SC connectors. It is built for storage area networks, high-speed parallel optics interconnects and other high-capacity links in new or upgraded building installations. The orange OFNR PVC jacket identifies the 50-micron fibre type at a glance.

Low-loss construction with aramid strength members

Two 900-micron buffered fibres are protected by aramid yarn that resists pulling tension during installation and routing. The cable achieves an ultra-low insertion loss of less than 3 dB, preserving signal integrity across the link. The ceramic ferrule connectors maintain consistent alignment for reliable throughput.

Not suited for single-mode

This cable does not support single-mode distances or wavelengths beyond the OM2 multimode specification. Buyers who need extended reach, higher bandwidth grades such as OM3 or OM4, or different connector combinations should select an alternative product.

Questions about this item

How do I install this LC-SC fibre patch cable and what step is often missed?

Align the LC and SC ferrules with the corresponding ports, push until both connectors click, then verify the link light — skipping the click check is the step most installers miss.

What maintenance or replacement will this OM2 50-micron cable need later?

Inspect and clean the ceramic ferrules periodically with a lint-free wipe and isopropyl alcohol; replace the patch cord if insertion loss rises above the rated 3 dB or if the orange OFNR jacket shows cracking.

What limit appears first when this 2 m duplex cable runs at sustained high throughput?

The 3 dB insertion-loss budget is the first constraint; multimode bandwidth-distance limits on 50-micron OM2 fibre are reached before the aramid-yarn strength members or 900-µm buffers degrade.
