Tripp Lite N858B-15M-3X8MG

Overview

The Tripp Lite N858B-15M-3X8MG is a multimode fiber optic cable designed to support high-speed network connections in environments like data centers, telecom rooms, and wiring closets. It uses 50/125 micron OM4 fiber to deliver Ethernet speeds up to 400 gigabit over short distances, ensuring low latency and strong signal integrity. With a length of 15 meters (49.2 feet), it is well suited for connecting equipment across rack rows or between adjacent network rooms.

Key features

• Supports multiple Ethernet speeds including 10, 25, 40, 100, and 400 gigabit, allowing seamless integration with existing and future network hardware.
• Uses OM4 multimode fiber for reliable performance on short-distance links, ideal for high-bandwidth applications.
• Equipped with three MTP/MPO PC female connectors on each end, each carrying eight fibers, which reduces cable clutter and simplifies cable management in dense network setups.
• Factory terminated and polished to ensure immediate installation without the need for field termination or additional certification.
• Features an LSZH (Low Smoke Zero Halogen) jacket that minimizes smoke and toxic emissions in case of fire, enhancing safety in areas with limited ventilation or strict fire codes.
• Distinct magenta jacket color makes it easy to identify and trace cables during maintenance or upgrades, reducing downtime and errors.

Connectivity and compatibility

This cable is designed to connect high-density patch panels, breakout cassettes, and switches that use MTP/MPO connectors. Its backward compatibility with 10 and 25 gigabit equipment means it fits well in mixed-speed network environments, allowing gradual upgrades without replacing cabling infrastructure. The three groups of eight fibers per connector support parallel optics configurations common in modern data center networks.

Ideal uses and environments

The cable is a strong choice for data centers and telecom rooms where high bandwidth and clean cable management are priorities. Its 15-meter length suits typical rack-to-rack or room-to-room connections, while the LSZH jacket ensures compliance with fire safety regulations in confined or poorly ventilated spaces. Network engineers will appreciate the ready-to-install design that reduces setup time and complexity.

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.
