ACT 50m Singlemode 9/125 OS2 Indoor/Outdoor 4-Fiber LC to LC Patch Cable, LSZH, Yellow RL2305

Long-distance fiber optic runs often suffer from signal loss and environmental vulnerabilities, but this ACT 50-meter OS2 singlemode cable eliminates those concerns with precision LC connectors and a rugged LSZH jacket. It delivers four independent 9/125µm fibers in one compact assembly, making it ideal for high-density links between buildings, across floors, or within data centers.

Who is it for

Network engineers, data center technicians, and system integrators who need a reliable, pre-terminated multi-fiber cable for indoor or outdoor backbone connections. It suits enterprise LANs, campus networks, and telecom installations where low attenuation and durable construction are critical.

Main features

• Singlemode OS2 fiber with 9/125µm core/cladding for long-haul performance up to 50 meters.
• Four fibers terminated with LC/UPC connectors on both ends (4xLC to 4xLC).
• Low insertion loss ≤0.25 dB per connector and high return loss ≥50 dB for stable links.
• LSZH (Low Smoke Zero Halogen) yellow jacket for safety in enclosed spaces and outdoor UV resistance.
• Operating temperature range -20°C to 70°C, suitable for harsh environments.
• Attenuation ≤0.35 dB/km at 1310nm and ≤0.25 dB/km at 1550nm.
• Compliant with RoHS and CE standards.

Tips

For outdoor runs, protect the connectors with dust caps when not in use and avoid bending beyond the minimum bend radius (typically 10x cable diameter). Use LC duplex clips if you need to pair fibers for bidirectional links. Always test with a power meter after installation to verify end-to-end loss.
