Tripp Lite N381L-05M

Overview

The Tripp Lite N381L-05M is a duplex singlemode OS2 fiber optic cable designed to support 400G Ethernet links up to 2 kilometers. With a 5-meter length, it is ideal for connecting equipment within racks, between adjacent cabinets, or across small data-center aisles without excess cable slack. One end features a compact CS UPC connector, which is about 40% smaller than a standard LC plug, while the other end uses a conventional LC UPC connector, allowing for higher port density on modern switches while maintaining compatibility with existing LC hardware.

This cable uses G657A2 bend-insensitive fiber, enabling tighter routing through crowded trays or around cabinet corners with reduced risk of signal loss. Its round jacket is made from low smoke zero halogen (LSZH) material and is colored yellow for easy identification of singlemode runs. The cable is backward compatible with 40G and 100G optics, making it a flexible choice for future network upgrades.

Key features

• Supports 400G Ethernet links up to 2 kilometers at 1310 nm wavelength, ensuring high-speed data transmission over long distances
• CS UPC connector on one end reduces connector size by about 40%, increasing port density on switches and patch panels
• Bend-insensitive G657A2 fiber allows for tighter cable routing with less signal degradation in dense or complex installations
• Low smoke zero halogen round jacket enhances safety by reducing toxic fumes in case of fire and simplifies cable management with its yellow color for quick singlemode identification
• Backward compatibility with 40G and 100G networks supports gradual infrastructure upgrades without replacing cabling
• Factory-terminated 5-meter length minimizes excess slack, improving airflow and reducing clutter in data centers
• Lifetime limited warranty from Tripp Lite provides confidence in long-term reliability and performance

Connectivity and compatibility

This cable is designed to connect high-density 400G switches or patch panels using the smaller CS UPC connector while maintaining compatibility with standard LC UPC ports on existing equipment. Its backward compatibility with 40G and 100G optics makes it suitable for mixed-speed environments and phased network upgrades. The singlemode fiber supports long-distance transmission, making it a strong choice for data centers and enterprise networks requiring reliable, high-speed connections.

Installation and setup

The 5-meter length is optimized to reduce excess cable slack, which helps maintain neat and efficient cable management in racks and cabinets. The bend-insensitive fiber allows installers to route the cable through tight spaces and around corners without risking signal loss. The yellow LSZH jacket not only meets strict safety standards but also makes it easy to identify singlemode cables among other fiber runs, simplifying maintenance and troubleshooting.

Ideal uses and environments

This fiber optic cable fits well in data centers, server rooms, and enterprise network environments where high-speed 400G Ethernet connections are required over distances up to 2 kilometers. It is particularly useful for setups that demand high port density and clean cable management, such as modern switch deployments and patch panels. Organizations planning future upgrades from 40G or 100G to 400G will benefit from its backward compatibility and durable design.

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.
