42M OM1 LC Fiber Optic Cable - High-Speed LC to LC Multimode

In this review the 42M OM1 LC fiber patch cable is evaluated for short-range, high-bandwidth networking needs. The bottom line: it is a straightforward multimode LC-LC jumper for data centers, telecom racks, and enterprise patch panels where reliable, low-loss signal delivery matters. The review highlights the cable's use of Corning glass core and ceramic ferrules, its reinforced zip-cord jacket for easier routing, and support for common Ethernet speeds up to 100Gb over short links, making it a practical choice for technicians and IT teams needing a tested OM1 jumper.

Key Features

• OM1 Multimode Fiber: The 50/125m OM1 core provides high modal bandwidth for short-range links common in data center patching and telecom closets.
• Corning Glass Core: Genuine Corning glass construction on the fiber core helps maintain consistent optical performance and low attenuation.
• Ceramic Ferrules: Precision ceramic ferrules on LC connectors reduce insertion loss and help preserve long-term signal integrity.
• Supports Multiple Speeds: Rated modal bandwidth supports 1Gb, 10Gb, 40Gb and short-range 100Gb links depending on distance requirements.
• Reinforced Zip-Cord Jacket: The 2.0mm jacket balances flexibility and durability for neat routing in racks, conduits, and patch panels.
• Standards Compliance: Inspected and tested to ANSI/TIA/EIA standards for consistent quality across production lengths from 0.5m to bulk options.

Who It's For

The cable is aimed at network administrators, rack technicians, and installers who need a reliable multimode LC-LC jumper for short-range connections in data centers, telecom rooms, and enterprise wiring closets. Its OM1 rating and Corning glass core make it suitable for legacy multimode runs and equipment that require LC connectors.

Those planning new long-distance multimode or singlemode backbone links should look elsewhere; singlemode fiber is the better choice for longer runs beyond the OM1 distance limits. Also, buyers needing specialty connectors other than LC should select a different jumper type.

Pros & Cons

Pros

• Good build quality with Corning glass core and ceramic ferrules that customers describe as working flawlessly in real deployments.
• Flexible, reinforced zip-cord jacket that simplifies routing and reduces kinking in tight panels.
• Supports a range of Ethernet speeds for short distances, offering versatility for data center patching tasks.
• Available in many lengths including long 42m (137.79ft) and bulk options for business purchases.

Cons

• OM1 multimode is limited for longer-distance 10Gb+ links compared with newer multimode grades or singlemode options.

Our Verdict

The 42m OM1 LC fiber cable is a sensible, value-minded choice for technicians who need a tested LC-LC multimode jumper for short-range data center and telecom patching. Its Corning core, ceramic ferrules, and reinforced jacket deliver dependable performance and easier installation, though installers requiring longer 10Gb+ runs should consider newer fiber grades or singlemode. For legacy multimode environments and bulk purchasing, it represents good value.

Frequently Asked Questions

What speeds does this OM1 cable support?
