ST-ST OM4 Fiber Patch Cable 90M - High-Speed Multimode

In this review the FiberCablesDirect ST-ST OM4 fiber patch cable is examined for data center and enterprise use; the bottom line is that it delivers reliable, low-loss multimode performance for short-range high-speed links. It is aimed at network engineers and IT teams who need a long, flexible duplex OM4 run with durable connectors. The most convincing reason to choose this cable is its Corning glass core and ceramic ferrules, which preserve signal integrity and make it a dependable choice for 10Gb and higher Ethernet in rack and patch panel environments.

Key Features

• OM4 multimode fiber: Supports high modal bandwidth for 1Gb, 10Gb, 40Gb and short-range 100Gb links, making it suitable for modern campus and data center backbones.
• ST-ST connectors: Durable bayonet-style ST connectors with ceramic ferrules provide consistent low insertion loss and easy field termination compatibility.
• Corning glass core: Genuine Corning OM4 fiber core helps maintain signal clarity and lowers attenuation compared with unspecified generic fiber.
• Reinforced zip-cord jacket: The 2.0mm jacket balances flexibility and durability so runs through racks and conduits are manageable without frequent kinking.
• Tested to industry standards: Inspected and tested to ANSI/TIA/EIA guidelines, giving confidence in long-term reliability for commercial installations.

Who It's For

The cable is best for network administrators, data center technicians, and telecom engineers who require a long OM4 duplex lead for patching between equipment racks, switches and optical transceivers. Its length and OM4 rating suit short to medium distance intra-building connections where 10Gb performance and low loss are needed.

Those who should look elsewhere include installers needing singlemode runs for long-haul connections or buyers who require different connector types such as LC or SC, since this product is specifically an ST-ST OM4 multimode patch cable.

Pros & Cons

Pros

• High bandwidth OM4 fiber that supports 10Gb and higher short-range links reliably.
• Corning glass core and ceramic ferrules for consistent, low-loss signal delivery.
• Flexible 2.0mm zip-cord jacket that simplifies routing and reduces kinks during installation.
• Compliant testing to ANSI/TIA/EIA standards gives installation confidence.

Cons

• ST connectors are less common than LC in some modern equipment, so adapter or transceiver compatibility should be verified.
• Multimode OM4 is not suitable for long-distance singlemode links beyond enterprise or data center short-range use.

Frequently Asked Questions

Will this cable support 10Gb Ethernet?
Yes, the OM4 specification supports 10Gb Ethernet up to about 300m and is well suited for typical data center patching distances.

Are the connectors durable for repeated re-patching?
Yes, the ST connectors use ceramic ferrules and a reinforced jacket designed for repeated handling in rack and patch panel environments.

Can this replace singlemode runs?
No, OM4 multimode is intended for short to medium distances; singlemode fiber is required for long-haul links.
