Tripp Lite N381L-001-MF

Overview

The Tripp Lite N381L-001-MF is a fiber optic cable adapter designed to connect standard LC fiber patch cables to network hardware featuring the newer CS interface. It supports 400 Gigabit Ethernet with a duplex singlemode 9/125 OS2 fiber design, enabling high-speed data transmission over distances up to 2 kilometers. This adapter is ideal for dense network environments such as cloud services, hyperscale data centers, and telecom facilities where space and performance are critical.

Key features

• Enables straightforward migration to 400 Gigabit Ethernet by converting LC patch cords to CS ports
• CS connector is approximately 40% smaller than LC plugs, allowing for higher port density in switch racks and patch panels
• Duplex singlemode 9/125 OS2 fiber maintains low insertion loss for reliable high-speed data transfer
• Bend-insensitive fiber design eases installation through tight bends and under-floor pathways
• Low-smoke zero-halogen (LSZH) yellow jacket enhances visibility in dimly lit racks and reduces toxic fumes in case of fire
• Backward compatible with 40 G and 100 G optics, supporting phased network upgrades without replacing existing equipment
• Complies with RoHS and REACH environmental standards for responsible procurement
• Lifetime limited warranty from Tripp Lite ensures long-term reliability and peace of mind

Connectivity and compatibility

This adapter bridges the gap between legacy LC fiber patch cables and modern CS interface ports, making it a practical choice for network engineers managing transitions to higher-speed infrastructure. Its compact CS connector frees up valuable rack space, which is especially beneficial in high-density switch environments. The adapter supports a wide range of equipment by maintaining compatibility with 40 G and 100 G optics, allowing gradual network modernization without full equipment replacement.

Ideal uses and environments

The Tripp Lite N381L-001-MF fits well in data centers, colocation facilities, and telecom setups where high port density and reliable 400 G connectivity are essential. Its 2-kilometer reach suits spine-leaf architectures, inter-building links, and cross-row connections. The bend-insensitive fiber and LSZH jacket make it suitable for installations requiring tight cable routing and enhanced safety in confined spaces. This adapter is a strong choice for network teams aiming to upgrade bandwidth while preserving existing cabling investments.

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.
