ST-ST OM4 Fiber Patch Cable 45M - High-Speed Multimode

In this review of the ST-ST OM4 fiber patch cable, the bottom line is clear: this 45M multimode lead is aimed at network engineers and IT teams who need reliable, low-loss short-range links. Our review finds it particularly well suited for data centers, telecom racks, and enterprise patch panels where consistent 10Gb performance matters. The use of Corning OM4 glass and ceramic ferrules is the single biggest reason to consider this cable, because it preserves signal integrity and makes connections predictable during high-bandwidth transfers.

Key Features

• OM4 multimode fiber: Delivers high modal bandwidth for reliable 10Gb and above operation in short-range links.
• ST-ST connectors with ceramic ferrules: Provide stable mating and low insertion loss for repeatable connections in patch environments.
• Corning glass core: Uses genuine Corning OM4 fiber to reduce attenuation and preserve throughput under load.
• Reinforced zip-cord jacket: The 2.0mm jacket balances flexibility and durability so the cable routes cleanly without kinking in racks and conduits.
• Standards compliance: Inspected and tested to ANSI/TIA/EIA conventions, giving confidence for deployment in commercial and institutional networks.
• Supports multiple Ethernet rates: Rated to support 1Gb, 10Gb, 40Gb, and short-range 100Gb applications depending on link length.

Who It's For

The ST-ST OM4 45M patch is ideal for data center technicians, telecom installers, and enterprise IT staff who need a dependable multimode link between switches, transceivers, and patch panels. It is a practical choice where 10Gb performance is required across moderate distances and where consistent connector quality matters.

Smaller home users or installations that require single-mode long-distance links should look elsewhere, since multimode OM4 is optimized for campus and rack-to-rack runs rather than long-haul backbone spans.

Pros & Cons

Pros

• Genuine Corning OM4 fiber and ceramic ferrules deliver low insertion loss and solid signal integrity.
• Zip-cord style 2.0mm jacket provides flexibility for neat routing and resistance to kinks in dense racks.
• Supports a range of Ethernet speeds, making it versatile for upgrades from 1Gb to 10Gb and short-range 40Gb/100Gb links.
• Inspected to industry standards, which reduces the chance of defective assemblies arriving on site.

Cons

• Multimode OM4 is not suitable for long-distance single-mode requirements, so it is limited to short to medium runs.
• ST connectors are less common in some modern switch ports compared with newer connector types, which may require adapters or transceiver choices.

Frequently Asked Questions

Will this cable support 10Gb Ethernet at 45M?
Yes. OM4 multimode is rated for 10Gb operation well beyond 45M, so it will support 10Gb links at this length.

Are these genuine Corning fibers?
Yes. The cable uses genuine Corning OM4 glass core with precision ceramic ferrules to maintain low insertion loss.

Is the jacket flexible enough for patch panels?
The 2.0mm reinforced zip-cord jacket balances flexibility and durability, making it suitable for routing in racks and patch panels.
