Description

The Sopto Duplex LC/UPC to LC/UPC OM2 Patch Cord – 2.0mm LSZH is a high-quality multimode fiber optic cable optimized for short-distance 10 Gbps transmission in LANs, data centers, and telecom environments. Built with OM2 (50/125 µm) graded-index multimode fiber, it provides low attenuation and excellent signal integrity across high-bandwidth applications.

Equipped with LC/UPC connectors on both ends, this duplex design supports simultaneous bidirectional communication and ensures stable performance with insertion loss ≤ 0.3 dB and return loss ≥ 35 dB. The 2.0 mm LSZH (Low Smoke Zero Halogen) jacket offers flame resistance and low toxicity, making it suitable for indoor and enclosed environments.

Compliant with IEC 61754, ISO/IEC 11801, and RoHS, this Sopto patch cord ensures dependable multimode connectivity for network switches, servers, ODF panels, and storage systems requiring OM2 optical links.
