MTRJ-MTRJ OM1 Fiber Patch Cable 85M - High-Speed Multimode

Our review of the MTRJ-MTRJ OM1 fiber patch cable focuses on practical performance for network and data center runs where legacy multimode connectivity is required. This 85 meter, duplex MTRJ-to-MTRJ jumper delivers the expected low loss and stable signal transmission thanks to Corning 62.5/125um core/cladding fiber construction. It is best for technicians and IT teams who need a reliable, long multimode jumper for 1Gb or short 10Gb runs and for environments that require an OFNR jacket and orange multimode identification.

Key Features

• Duplex MTRJ Termination: Two fiber strands in an MTRJ-to-MTRJ layout provide simple duplex connections for compatible switches and transceivers.
• OM1 Multimode Fiber: The 62.5/125um Corning multimode core is designed for stable 1Gb links and short 10Gb links where legacy OM1 is still in use.
• 85 meter Length: At about 278.87 ft this length suits medium to long patching runs inside telecom rooms and between racks without splicing.
• OFNR PVC Jacket: The orange, zip-cord reinforced 2.0mm PVC jacket meets riser flame requirements and makes cable routing and identification straightforward.
• Low Loss, Reliable Transmission: Constructed to minimize insertion loss so it performs well in enterprise and education networks where consistent throughput matters.
• Compact Diameter: The 2.0mm outer diameter keeps bundles manageable and reduces congestion in patch panels and conduits.

Who It's For

This cable is aimed at IT professionals, network installers, and data center technicians who maintain or extend existing multimode fiber infrastructures, particularly in education, healthcare, government, and commercial settings. It is a practical choice when continuity with 62.5um OM1 systems is required and where MTRJ connectors are a supported interface.

Those who need maximum 10Gb reach at long distances, singlemode connectivity, or the absolute latest multimode performance should look elsewhere; OM1 is limited in 10Gb distance compared with OM3/OM4 fiber and will not replace singlemode links for long-haul or very high-density core runs.

Pros & Cons

Pros

• Good build quality and connector reliability, matching customer reports of solid functionality with common gear.
• Long 85m length covers many in-building patch needs without splices or additional connectors.
• OFNR jacket and compact 2.0mm zip-cord design simplify installation and routing in racks and conduits.
• Corning 62.5/125um core offers predictable multimode behavior for legacy systems.

Cons

• OM1 fiber limits 10Gb distances to short runs at 850 nm, so it is not ideal for longer 10Gb backbones.
• MTRJ connector is less common than LC/SC in newer equipment, which may require adapters or replacements.

Our Verdict

The MTRJ-MTRJ OM1 85m patch cable is a sensible, cost-conscious choice for teams maintaining legacy multimode networks who need a long, dependable jumper with Corning 62.5/125um fiber and an OFNR jacket. It offers solid value for 1Gb applications and short 10Gb links, but those upgrading to modern, higher-bandwidth multimode or singlemode infrastructure should select newer fiber types or connector formats.

Frequently Asked Questions

Will this cable support 10Gb Ethernet?
Yes, it supports 10Gb at short distances: OM1 is typically rated to about 33 m at 850 nm for 10Gb links.

Is the cable suitable for in-building riser installations?
Yes, the OFNR PVC jacket is riser-rated and the 2.0 mm zip-cord design is suitable for standard in-building routing.

What equipment is compatible with MTRJ connectors?
MTRJ connectors are used on some legacy transceivers and patch panels; ensure your switch or transceiver supports MTRJ or plan to use adapters for LC/SC equipment.
