Tripp Lite 400G Duplex Singlemode 9/125 OS2 Fiber Optic Cable Adapter (CS-UPC/LC-UPC), M/F, Round LSZH Jacket, Yellow, 1 ft.

The Tripp Lite N381L-001-MF is an adapter that lets you connect a standard LC fiber patch cable to network hardware that uses the newer CS interface. It uses fiber in a duplex singlemode 9/125 OS2 design and is rated for 400 Gigabit Ethernet, so it can handle the heavy data flows found in cloud services, hyperscale data centers, and telecom facilities.

At just one foot in length, the adapter fits neatly between a patch panel and a nearby transceiver or inside crowded switch racks. The CS plug is about forty percent smaller than an LC connector, giving engineers more ports per blade while preserving the LC cabling already in place on the other side.

The fiber carries signals at the 1310 nanometer wavelength for distances up to two kilometers, making it practical for spine-leaf links, inter-building runs, or cross-row connections in colocation spaces. Bend-insensitive glass helps the cable tolerate the tight turns often required by vertical managers and under-floor pathways.

A jacket made of low-smoke zero-halogen material in bright yellow coloring improves visibility in dimly lit racks and limits toxic fumes in case of fire. The adapter is also backward compatible with 40 G and 100 G optics, allowing teams to modernize portions of the network without retiring older equipment.

Compliance with RoHS and REACH directives supports responsible procurement, and the lifetime limited warranty from Tripp Lite provides long-term peace of mind for integrators and operators alike.

Highlights:

• Supports 400 Gigabit Ethernet links up to 2 km at a 1310 nm wavelength
• Converts an LC patch cord to a CS port for straightforward 400 G migration
• CS connector uses about forty percent less space than an LC plug, ideal for high port density
• Fiber with a duplex singlemode 9/125 OS2 design keeps insertion loss low at high data rates
• LSZH jacket in yellow reduces smoke and is easy to spot in crowded racks
• Bend-insensitive fiber simplifies routing through tight spaces
• Backward compatibility with 40 G and 100 G equipment supports phased upgrades
• Meets RoHS and REACH environmental standards
• Backed by a lifetime limited warranty from Tripp Lite
