Tripp Lite 400G Duplex Singlemode 9/125 OS2 Fiber Optic Cable (CS-UPC/LC-UPC), Round LSZH Jacket, Yellow, 3 m

Overview

The Tripp Lite N381L-03M is a 3-meter duplex singlemode fiber optic cable designed to support 400 Gb Ethernet traffic over distances up to 2 kilometers. It features a CS-UPC connector on one end and an LC-UPC connector on the other, enabling high-density connections in data centers and telecom environments. This cable is built with 9/125 micron OS2 fiber that meets the G657A2 bend-insensitive standard, ensuring reliable performance even in tight cable routing scenarios.

Key features

• Supports 400 Gb Ethernet links on OS2 singlemode fiber for long-distance data transmission up to 2 km
• CS-UPC connector footprint is about 40 percent smaller than standard LC, allowing higher port density in switches and patch panels
• Compatible with QSFP-DD transceivers and backward compatible with 40 Gb and 100 Gb equipment for seamless network upgrades
• Bend-insensitive G657A2 fiber reduces signal loss when routed tightly inside racks or cable managers
• Low smoke zero halogen (LSZH) jacket in bright yellow for easy singlemode identification and enhanced safety in case of fire
• 3-meter length is well suited for patch panel to switch or rack-to-rack connections within data centers and telecom rooms

Connectivity and compatibility

This cable is designed to connect QSFP-DD transceivers with a compact CS interface to standard LC ports, enabling high-density setups without replacing existing singlemode infrastructure. It works well in environments where space is limited and high throughput is required, such as hyperscale cloud data centers, enterprise server rooms, and telecom racks. Its backward compatibility with 40 Gb and 100 Gb equipment allows gradual network upgrades without costly overhauls.

Ideal uses and environments

The Tripp Lite N381L-03M fits well in data centers and telecom rooms where high bandwidth and space efficiency are priorities. Its 3-meter length is ideal for connecting patch panels to switches or linking racks within the same room. The cable’s bend-insensitive fiber and LSZH jacket make it suitable for dense cable management systems and environments with strict safety regulations. This cable is a strong choice for network engineers and IT professionals aiming to future-proof their infrastructure while maintaining compatibility with existing gear.
