Fibtele technical configuration brief
Product: OS2 Duplex LC Fiber Patch Cord for FR4/LR4 and DCI
Catalog slug: os2-duplex-lc-fr4-lr4-dci-patch-cord
Category: ai-data-center-fiber-cabling

Published technical record
This duplex OS2 LC/UPC patch cord is intended for wavelength-multiplexed optical modules that present duplex LC interfaces, including supported FR4, LR4, and data center interconnect applications. The two-fiber format is distinct from parallel MPO cabling. Final reach and wavelength support are determined by the selected transceivers and total channel loss.

Features
- Two 9/125 µm OS2 single-mode fibers in a compact duplex construction.
- Duplex LC/UPC connectors for compatible FR4, LR4, and other wavelength-multiplexed optical modules.
- Yellow jacket supports clear single-mode identification in dense rack environments.
- Compact LC footprint is suitable for high-density switch and patch-panel ports.
- A-to-B polarity supports transmit-to-receive alignment in common duplex links.
- Custom length, jacket rating, connector boot, labels, and test documentation are available by configuration.
- Confirm UPC/APC interface, wavelength, reach, and link loss budget for the selected optical modules.

Applications
- 400G FR4 and LR4 optical links with duplex LC interfaces
- Data center interconnect and campus links
- AI data center spine and core connectivity
- Wavelength-multiplexed switch-to-switch links
- Structured OS2 patching between equipment and fiber panels
