OM4 fibre cable for 10G to 100G links

This 20 metre duplex cable uses 50/125 micrometer OM4 fibre with LC/UPC and SC/UPC male connectors. It is built for enterprise networks, telecom rooms, server farms and cloud storage networks that need high-throughput multimode connections.

Capacity and headroom for 10G 40G 100G

The cable supports 10G transmissions up to 400 metres and 40G or 100G transmissions up to 100 metres. At 20 metres it provides ample headroom for all three speeds, while OM4 specification allows longer runs than OM3. Beyond 100 metres at 40G or 100G the link budget is exceeded and signal integrity drops.

OFNR rating and multimode interface limits

The OFNR jacket meets riser flame ratings for vertical runs between floors. Multimode fibre limits reach compared with single mode, so distances above 100 metres at 40G or 100G require different cable types. The 2.0 mm diameter and aramid yarn strength member aid handling but do not extend the optical loss budget.

Questions about this item

Will this 20 m OM4 duplex cable connect cleanly to my existing SC/UPC patch panel and LC/UPC transceivers?

Yes, the cable terminates with SC/UPC on one end and LC/UPC on the other, both male connectors, matching standard SC and LC patch panels and transceiver interfaces.

How can I verify the link is performing to OM4 specification after installation?

Check that the link reports 10 Gbps up to 400 m or 40 Gbps and 100 Gbps up to 100 m with low loss; the bend-insensitive fiber and aramid yarn strength member help maintain those distances.

Does the 139429 cable include dust caps or cleaning wipes, or must I buy them separately?

The cable ships with the duplex 2.0 mm jacketed assembly and integrated connectors; dust caps and cleaning supplies are not included and should be sourced separately.
