Black Box EFNT010-003M-STLC

Overview

The Black Box EFNT010-003M-STLC is a 9.8-foot fiber optic patch cable designed for high-speed 10 Gigabit Ethernet connections. It uses OM3 50/125 multimode fiber optimized for laser light sources, delivering bandwidth up to 2000 MHz km. This cable is ideal for backbone runs up to 300 meters, making it suitable for linking wiring closets, campus buildings, or server racks with reliable performance across a wide temperature range.

Key features

• Supports 10 Gigabit Ethernet over multimode fiber for fast and stable network connections
• Laser-optimized fiber ensures high bandwidth and compatibility with both laser and LED transmitters
• Tight-buffered construction with acrylate coating protects the fiber strands from damage
• Aramid yarn strength members provide pull resistance during installation, reducing the risk of cable damage
• Durable PVC jacket resists abrasion and helps maintain cable integrity and bend radius
• Wide operating temperature range from -40 °F to 185 °F allows use in various indoor environments including data centers and factory floors
• Factory-terminated ST connector on one end and LC connector on the other enable seamless connection between legacy and modern equipment

Key specs

Connectivity and compatibility

This cable bridges older and newer fiber optic equipment by combining an ST connector on one end with an LC connector on the other. This design simplifies upgrades and integration in mixed environments without requiring additional adapters. It works well in setups where legacy hardware must connect to modern switches or transceivers, supporting smooth data flow across diverse network infrastructures.

Ideal uses and environments

The cable is well suited for data centers, colocation facilities, and campus networks where high-speed backbone connections are essential. Its robust construction and wide temperature tolerance make it reliable in demanding indoor settings such as factory floors or server rooms. It also fits rack-to-rack or workstation-to-switch connections where a 3-meter length is practical for neat cable management and minimal signal loss.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
