BLACKBOX FO OS1/2 SINGLE-MODE PATCH CABLES LSZH - LC-LC DUPLEX, 1M

For fibre links where every decibel counts, this BLACKBOX OS1/2 single-mode patch cable pairs a 9/125µm core with low-loss LC duplex connectors and an LSZH jacket, delivering stable 1310nm and 1550nm transmission over 1 metre without the smoke or toxicity risks of PVC. Typical alternatives bundle single-mode fibre in halogenated jackets or skip duplex polarity marking; here the A-B orientation is built in, and insertion loss stays under 0.3dB per mated pair.

Highlights

• OS1/OS2 single-mode fibre, 9/125µm core/cladding, optimised for 1310nm and 1550nm wavelengths
• LC-LC duplex connectors with UPC polish: return loss ≥50dB, insertion loss ≤0.3dB
• Low Smoke Zero Halogen (LSZH) yellow jacket, 2.0mm diameter, RoHS compliant
• 1-metre length with A-B polarity for correct duplex channel mapping
• Meets TIA/EIA-568-C.3 and IEC 60794-2 performance requirements

In daily use

Patch panels, SFP/SFP+ transceivers, and fibre distribution frames all benefit from the tight bend tolerance and consistent geometry of this assembly. The LSZH jacket stays flexible from -20°C to 70°C operating temperature, so it routes cleanly in crowded racks and enclosed cable managers. Duplex LC clips lock into transceivers and adapters with a firm click, and the A-B polarity marking removes guesswork during moves, adds, and changes.

Final note

When a 1-metre single-mode patch cable must perform in air-handling spaces or densely packed enclosures, the BLACKBOX LSZH LC-LC duplex assembly delivers the optical headroom and safety profile that standard PVC jumpers cannot match.
