Black Box EFNT010-003M-SCLC

Overview

The Black Box EFNT010-003M-SCLC is a 9.8-foot OM3 multimode fiber optic patch cable designed to support high-speed 10 Gigabit Ethernet connections without the need to switch to single mode fiber. Featuring an SC connector on one end and an LC connector on the other, this cable bridges traditional backbone equipment with newer high-density optics. Its laser-optimized 50/125 micron fiber delivers bandwidth of 2000 MHz per kilometer and supports data transmission up to 300 meters, making it a reliable choice for data centers, storage area networks, and campus backbones.

Key features

• OM3 multimode fiber optimized for laser transmission ensures high bandwidth and data rates suitable for demanding network environments.
• SC to LC connectors provide compatibility between legacy and modern networking hardware, simplifying upgrades and expansions.
• Aqua jacket color allows quick identification of OM3 cables in crowded patch panels, reducing troubleshooting and maintenance time.
• Tight buffered core with a durable PVC jacket protects the fiber from physical damage and repeated handling in patch panels and cabinets.
• Wide operating temperature range from -40 to 185 degrees Fahrenheit ensures stable performance in various installation environments, including wiring closets and utility tunnels.
• At 9.8 feet (3 meters), the cable length is ideal for connecting adjacent racks or linking racks to nearby wall panels without excess slack.

Connectivity and compatibility

This patch cable is designed to connect equipment with SC and LC fiber optic ports, making it suitable for integrating older backbone hardware with newer high-density optical devices. It supports 10 Gigabit Ethernet networks and is well suited for data center switch interconnects, storage area networks, and campus backbone links where multimode fiber is preferred over copper cabling.

Performance and reliability

The cable’s laser-optimized OM3 fiber ensures high bandwidth and low signal loss over long distances, supporting up to 300 meters at 10 Gb/s. Its tight buffered core and robust PVC jacket provide protection against physical stress and environmental factors, maintaining consistent performance even in less controlled temperature conditions. This durability makes it a dependable choice for demanding network environments.

Ideal uses and environments

This fiber optic patch cable fits well in data centers, enterprise networks, and campus infrastructures where high-speed multimode connections are required. It is especially useful for network administrators who need to bridge legacy SC-based equipment with modern LC-based devices while maintaining 10 Gigabit Ethernet speeds. The cable’s length and durability also make it practical for wiring closets and equipment rooms with limited space.

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.
