Lightwin LDP-09 FC-LC 3.0 OS2 Single-mode Duplex Fiber Patch Cable, 3m, Yellow LSZH, FC to LC UPC

Data center technicians and network engineers often need a dependable link between legacy FC patch panels and modern LC-equipped switches. The Lightwin LDP-09 FC-LC 3.0 duplex patch cable solves that mismatch with a 3-meter OS2 single-mode run, terminated with FC on one end and LC on the other. It's the kind of cable you install once and forget, thanks to precision UPC polishing and low insertion loss.

Key specifications

• Fiber type: OS2 single-mode, 9/125 µm core/cladding
• Connectors: FC duplex (A) to LC duplex (B), UPC polish
• Length: 3 meters
• Jacket: Yellow LSZH (Low Smoke Zero Halogen)
• Insertion loss: < 0.3 dB
• Return loss: > 50 dB
• Attenuation: ≤ 0.4 dB/km @ 1310 nm, ≤ 0.3 dB/km @ 1550 nm
• Operating temperature: -20°C to 70°C
• Minimum bend radius: 30 mm
• Compliance: RoHS, CE

Why choose it

This patch cable bridges the gap between older FC infrastructure and today's high-density LC ports without adapters or hybrid jumpers. The duplex construction keeps transmit and receive fibers together, reducing cable clutter. LSZH jacketing means it won't emit toxic fumes in a fire, making it suitable for enclosed spaces. With a return loss above 50 dB, it preserves signal integrity for high-speed links.

Ideal use cases

• Connecting FC patch panels to LC switches in data centers
• Linking test equipment with FC ports to LC-based systems
• Extending single-mode runs in enterprise backbones
• Telecom rooms where low smoke and halogen-free materials are required

Good to know

Each connector is individually tested for insertion and return loss. The 3-meter length is ideal for intra-rack or adjacent rack patching. Store the cable at temperatures between -40°C and 85°C when not in use. Keep bends above 30 mm radius to avoid microbending losses.
