LC-ST OM4 Fiber Patch Cable 70M - High-Speed Multimode

In this review of the LC-ST OM4 fiber patch cable the bottom line is clear: this 70M multimode lead is aimed at network engineers and IT teams who need reliable, low-loss short-range links in data centers and telecom racks. The reviewer found it delivers consistent 10Gb performance and good handling for patching and cross-connects, with the biggest reason to buy being its Corning OM4 glass core and ceramic ferrules that preserve signal integrity for critical links.

Key Features

• OM4 Multimode: The 50/125m OM4 fiber delivers higher modal bandwidth for dependable 10Gb and short-range 40Gb/100Gb connections in enterprise environments.
• LC-ST Connectors: The mixed LC to ST termination offers flexibility when connecting to different transceivers and legacy equipment without extra adapters.
• Corning Glass Core: Genuine Corning OM4 fiber combined with ceramic ferrules keeps insertion loss low and maintains consistent signal quality across runs.
• Reinforced Zip-Cord Jacket: The 2.0mm jacket improves flexibility and resists kinking, making rack and conduit routing simpler during installation.
• Standards Compliance: Cables are inspected and tested to ANSI/TIA/EIA standards, providing confidence in long-term durability and performance.

Who It's For

This cable is best for data center technicians, telecom installers, and enterprise IT staff who need a reliable OM4 multimode patch for 10Gb short-range links and occasional 40Gb or 100Gb short-range connections. Its mixed LC-ST termination is particularly useful where a device or panel accepts ST at one end and LC at the other.

Those who need singlemode runs for long-haul backbone links, or fiber leads shorter than 1m for desktop patching, should look elsewhere; this product is optimized for 70m multimode use in rack, conduit, and patch panel environments rather than ultra-short workstation jumper cables.

Pros & Cons

Pros

• High-quality Corning OM4 glass and ceramic ferrules produce low insertion loss and stable throughput at 10Gb.
• Zip-cord 2.0mm jacket balances flexibility and durability for neat cable management in dense racks.
• Supports multiple Ethernet speeds and distances, making it versatile for mixed-speed environments.

Cons

• At 70M length it is not intended for long singlemode backbones, so it is unsuitable for long-distance campus links.

Specifications

Our Verdict

This LC-ST OM4 70M patch cable is a practical, cost-effective choice for data center and enterprise teams needing reliable short-range multimode connectivity. With Corning glass, ceramic ferrules, and a durable zip-cord jacket, it delivers consistent 10Gb performance and flexible termination options, making it a good value for most rack and telecom patching tasks.

Frequently Asked Questions

Will this cable support 10Gb Ethernet?
Yes. The OM4 multimode specification supports 10Gb up to the distances expected for multimode fiber, and customers report good 10Gb performance.

Can I use this for 40Gb or 100Gb?
It supports short-range 40Gb and 100Gb links within OM4 distance limits, but check transceiver and channel requirements for those higher speeds.

Is the cable durable for rack installations?
Yes. The reinforced 2.0mm zip-cord jacket improves flexibility and resists kinking during routing in racks and conduits.
