Black Box FOSM-005M-LCLC

Overview

The Black Box FOSM-005M-LCLC is a 16.4-foot OS2 9/125 single-mode fiber optic patch cable designed to provide reliable, high-speed connections for Gigabit and 10 Gb network applications. Its duplex LC to LC connectors and 2.0 millimeter zipcord construction make it an efficient solution for linking network devices in environments where signal integrity and uptime are critical. The cable’s yellow OFNR-rated PVC jacket is suitable for riser installations, making it ideal for vertical runs in office buildings or data centers.

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.
