ST-ST OM2 Fiber Patch Cable 85M - High-Speed Multimode

In this review of the ST-ST OM2 Fiber Patch Cable 85M, the bottom line is clear: this is a straightforward, workhorse multimode patch lead for short-range, high-bandwidth links. IT teams, data center technicians, and telecom installers will appreciate the cable for its 10Gb-ready OM2 performance and durable zip-cord construction that eases routing in racks and conduit. The review focuses on real-world use: reliable low-loss connections provided by Corning glass fiber and ceramic ferrules, practical flexibility for dense patch panels, and predictable compliance with industry standards.

Key Features

• OM2 multimode fiber: Supports short-range, high-bandwidth links and is specified to handle 1Gb, 10Gb, 40Gb, and short-range 100Gb connections where OM2 modal bandwidth is sufficient.
• ST-ST connectors: Bayonet-style ST connectors with ceramic ferrules deliver repeatable low insertion loss for patch panel and field terminations.
• Corning glass core: Genuine Corning OM2 fiber provides consistent attenuation characteristics for predictable signal delivery in enterprise and telecom racks.
• Reinforced zip-cord jacket: The 2.0mm jacket balances flexibility and durability to reduce kinking and simplify cable management in dense installations.
• Standards tested: Inspected and tested to ANSI/TIA/EIA guidelines to ensure each cable meets established performance and durability expectations.
• Bulk length: The 85M (278.87ft) length is useful for long runs inside large data halls or between telecom closets without splicing.

Who It's For

The cable suits network engineers and facilities teams needing a long multimode ST-ST run inside data centers, server rooms, or campus telecom spaces. It is especially useful where 10Gb Ethernet is required across moderate short-range distances and where installers prefer the robustness and repeatability of ceramic-ferruled ST connectors.

Those who need very long-distance singlemode links, duplex LC patching for optics with LC interfaces, or ultra-low-latency fiber for specialized lab optics should look elsewhere. Also, environments requiring bend-insensitive OM4/OM5 modal bandwidth for maximum headroom would be better served by a higher-grade multimode fiber.

Pros & Cons

Pros

• Long 85M length eliminates intermediate splices for many enterprise and telecom runs.
• Corning OM2 glass and ceramic ferrules provide reliable, low-loss connections for consistent performance.
• Zip-cord 2.0mm jacket gives flexibility for neat routing in racks and patch panels.
• Compliant with ANSI/TIA/EIA testing and inspection for predictable field results.

Cons

• OM2 offers less modal bandwidth headroom than OM3/OM4 for future higher-speed short-reach needs.
• ST connectors are less common than LC in modern transceiver-dense equipment, so adapter or patching changes may be needed.

Its use of Corning glass and ceramic ferrules makes it a durable workhorse for patching and interconnect tasks, though buyers seeking maximum future-proofing may prefer OM3/OM4 alternatives.

Frequently Asked Questions

Can this cable run 10Gb Ethernet?
Yes, OM2 multimode is specified to support 10Gb Ethernet up to typical OM2 distances, making this cable suitable for many short- to mid-range 10Gb links.

Are ST connectors compatible with all equipment?
ST connectors are common in legacy and some telecom gear, but many modern transceivers use LC; adapters or patching may be required for LC-only equipment.

Is the cable tested for standards compliance?
Yes, units are inspected and tested to ANSI/TIA/EIA standards for performance and durability.
