Black Box EFN310-005M-SCSC

Overview

The Black Box EFN310-005M-SCSC is a singlemode fiber optic patch cable designed to provide reliable, long-distance network connections. Measuring 5 meters (16.4 feet), it is ideal for typical rack-to-rack or rack-to-panel runs within data centers or telecom rooms. The cable uses OS2 9/125 micron fiber, supporting transmission at 1310 and 1550 nanometers, which ensures clear and consistent signal quality over extended distances.

Its yellow PVC jacket meets OFNR riser fire codes, making it easy to identify and safe for use in riser environments. The cable’s robust construction offers strong tensile strength and crush resistance, protecting the delicate glass fiber during installation and operation in a wide temperature range from -4 to 158 °F (-20 to 70 °C).

Key features

• Singlemode OS2 fiber delivers significantly longer reach compared to multimode cables, supporting backbone and telecom applications.
• 5-meter length fits common patching needs inside cabinets and closets without excess slack.
• LC to LC connectors with precision ceramic ferrules reduce insertion loss and maintain stable network performance.
• Yellow OFNR-rated PVC jacket enhances cable identification and complies with riser fire safety standards.
• Durable design resists crushing and withstands strong pulls during installation, protecting fiber integrity.
• Wide operating temperature range allows use in both conditioned data centers and warmer utility spaces.
• Meets ANSI/TIA/EIA-568B.3 standards, ensuring compatibility and performance with industry equipment.
• Supports common singlemode wavelengths of 1310 nm and 1550 nm for versatile network deployment.

Connectivity and compatibility

This patch cable is compatible with a wide range of singlemode fiber optic equipment, including core switches, storage arrays, and telecom devices that use LC connectors. Its adherence to ANSI/TIA/EIA-568B.3 standards ensures seamless integration into existing network infrastructures that require reliable, low-loss fiber connections.

Ideal uses and environments

Well suited for backbone segments, telecom rooms, and service-provider handoffs, this cable performs reliably in both controlled data center environments and warmer utility spaces. Its length and durability make it a practical choice for network professionals managing rack-to-rack or rack-to-panel connections where signal integrity and compliance with fire safety codes are essential.

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.
