FiberCablesDirect LC-LC OM4 Fiber Patch Cable - 70M High-Speed

In this review of the FiberCablesDirect LC-LC OM4 fiber patch cable, the bottom line is simple: it is a reliable, high-bandwidth multimode jumper for short- to medium-range 10Gb and higher links. The 70m length and Corning OM4 glass core make it a practical choice for data centers, telecom racks, and enterprise patch panels where low insertion loss and durability matter. The review finds it particularly useful for network engineers who need a tested, zip-cord duplex cable that balances flexibility and signal integrity without paying premium custom prices.

Key Features

• Corning OM4 Glass: Provides high modal bandwidth and low attenuation for consistent performance on 10Gb, 40Gb, and 100Gb short-range links.
• LC-LC Duplex Connectors: 1.25mm ceramic ferrules on LC-UPC connectors ensure precise mating and reduced insertion loss in patch panels and transceiver ports.
• 70m Length: A 70 meter (229.65 ft) run covers many data center and campus connections without intermediate splices, simplifying cable management.
• Zip-Cord Reinforced Jacket: The 2.0mm zip-cord construction improves flexibility and resists kinks for easier routing in racks and conduits.
• Standards Compliance: Inspected and tested to ANSI/TIA/EIA standards for predictable long-term behavior in commercial installations.

Who It's For

This cable is aimed at network administrators, data center technicians, and telecom installers needing a reliable duplex multimode link for short-range high-speed networks. It fits scenarios where standard OM4 performance is required for 1Gb through 100Gb short-range connections and where connector quality and low loss matter.

It is less appropriate for long-haul singlemode runs, situations requiring custom jacket colors or armoring, or environments that demand armored or plenum-rated cable unless you confirm those requirements separately.

Pros & Cons

Pros

• High-quality Corning OM4 fiber provides solid bandwidth and low-loss transmission for 10Gb and higher links.
• Precision ceramic ferrules on LC connectors deliver reliable mating and consistent signal integrity.
• Zip-cord 2.0mm jacket offers flexibility for clean routing and reduced kinking during installation.
• Bulk length and testing make it a cost-effective option for enterprise and data center deployments.

Cons

• Not a substitute for singlemode fiber on long-distance links; intended for short-range multimode use only.
• Standard jacket without specialized plenum or armored options may not meet all building codes or harsh-environment needs.

Frequently Asked Questions

Will this cable support 10Gb Ethernet over 70m?
Yes, OM4 multimode supports 10Gb Ethernet well beyond 70m; this 70m cable is within the recommended range for 10Gb links.

Are the connectors factory polished?
Yes, the cable uses LC-UPC terminations with 1.25mm ceramic ferrules for low insertion loss and consistent mating.

Is this cable suitable for outdoor or armored installations?
No, the standard zip-cord jacket is intended for indoor rack and conduit use; specialized outdoor or armored variants would be needed for harsh environments.
