Tripp Lite by Eaton 400G Duplex Singlemode OS2 Switchable Fiber Patch Cable LC/UPC to LC/UPC, LSZH, 1m Yellow

The Tripp Lite by Eaton N370X-01M is a 1-metre duplex OS2 singlemode (9/125 µm) fiber patch cable with LC/UPC connectors at both ends, built for patching 10G to 400G singlemode optics in racks and data rooms. Its LC connectors let you swap the polarity of the pair in seconds, without tools and without re-terminating the cable, which is the usual fix when a new link stays dark because transmit is facing transmit.

The jacket is low-smoke zero-halogen (LSZH) and rated OFNR, in the yellow colour used across the industry for singlemode, so the cable is easy to tell apart from aqua or violet multimode cords in a crowded panel. A flat 2.0 × 4.1 mm duplex profile and a 10 mm static bend radius keep it tidy in vertical managers and short switch-to-panel runs.

• 1 × N370X-01M duplex OS2 LC/UPC patch cable, 1 m
• Protective dust caps on the connectors

• Patches a singlemode switch or router port to a fibre patch panel, or links two devices in the same rack, at any speed their optics support from 1G up to 400G over duplex LC.
• If a newly installed link shows no light, flip the polarity on one LC duplex clip instead of crossing fibres or ordering a different cable.
• LSZH jacket is the safer choice for enclosed rooms and the jacket type many EU building specifications ask for indoors.
• At 1 m it suits top-of-rack patching and short jumps between adjacent devices; for longer runs ask us for the next length up.

• Multimode optics (SR, SX, 850 nm) — they need OM3/OM4/OM5 multimode cable, not OS2 singlemode.
• APC (angled, green) connectors or adapters — mating UPC to APC causes high loss and can damage the end faces.
• 400G optics with MPO/MTP interfaces (e.g. DR4, SR8) — these need an MPO trunk or breakout, not a duplex LC cord.
• Outdoor or direct-burial runs — this is an indoor OFNR patch cable.
