Tripp Lite 400G Duplex Singlemode 9/125 OS2 Fiber Optic Cable (CS-UPC/LC-UPC), Round LSZH Jacket, Yellow, 5 m

The Tripp Lite N381L-05M is a duplex singlemode OS2 fiber optic cable designed for 400G Ethernet links up to 2 kilometers. With a manageable 5-meter reach, it neatly connects equipment within a rack, between adjacent cabinets, or across a small data-center aisle without creating extra slack.

One end of the cable uses a CS UPC connector and the other uses an LC UPC connector. The CS interface is about forty percent smaller than an LC plug, so network engineers can increase port density on modern switches or patch panels while still pairing with existing LC hardware on the far end.

The fiber meets the G657A2 bend-insensitive standard, allowing tighter routing through crowded trays or around cabinet corners with less risk of signal loss. This helps installers work faster and keeps links reliable even in dense environments.

A round jacket made from low smoke zero halogen material satisfies strict safety requirements and features a yellow color that lets technicians identify singlemode runs at a glance.

The cable remains backward compatible with 40G and 100G optics, making it a practical choice for organizations that want to install cabling once and upgrade transceivers later. Tripp Lite covers the assembly with a lifetime limited warranty for added peace of mind.
