Tecowin Fiber Lead 9/125, LC-LC, duplex, SMF, 3M

High-speed optical connections demand precision and reliability. The Tecowin Fiber Lead 9/125 with LC-LC duplex connectors delivers a stable single-mode link for data centers, telecom rooms, and enterprise networks. Its 3-meter length bridges short-distance patching without excess slack, while the 9/125 µm core/cladding preserves signal integrity over 1310 nm and 1550 nm wavelengths.

Who is it for

Network engineers and IT technicians who need a dependable duplex fiber patch cable for interconnecting switches, routers, media converters, and fiber distribution panels. Ideal for structured cabling systems that follow TIA/EIA-568-C.3 guidelines.
