Fiber optic patch cable SC/APC to LC/UPC simplex 9/125µm singlemode 20m white 3mm LSZH

Simplex singlemode fiber optic patch cable SC/APC to LC/UPC, 9/125µm, 20 m length, 3 mm jacket diameter with LSZH outer sheath. This cable provides a single optical path between devices and is suitable for low‑loss connections in telecom equipment, data centres, patch panels and field installations where a compact, reliable singlemode link is required. The SC/APC to LC/UPC connector combination supports mating with angled‑polished (APC) and ultra‑polished (UPC) terminations to maintain consistent return loss and insertion loss performance.

Advantages

The LSZH sheath reduces hazardous smoke and toxic gas in case of fire while maintaining mechanical protection and flexibility in indoor installations. A 3 mm round jacket balances durability with easy routing through cable management systems and conduits. The 9/125µm singlemode core supports long‑distance, low‑attenuation transmission and compatibility with common singlemode transceivers and optical equipment. Factory‑terminated connectors ensure consistent polishing quality and predictable optical performance for plug‑and‑play deployment.

Suitable for

• Optical patching between telecom devices, ODFs and switch panels
• Fiber links in data centres, server rooms and network cabinets
• Indoor installations requiring low‑smoke, flame‑retardant cabling
• Field splicing and temporary test links where SC/APC to LC/UPC mating is needed

• Outer sheath: LSZH (low smoke zero halogen)
• Polish types: angled (APC) on SC end, ultra‑polished (UPC) on LC end
• Construction: simplex (single fiber)

How to use

Connect the SC/APC end to the matching SC/APC adapter or port and the LC/UPC end to the corresponding LC/UPC port, ensuring proper alignment and cleaning of connector endfaces before insertion. Avoid bending the cable below the recommended minimum bend radius to prevent increased insertion loss or fiber damage. Secure the cable in cable management trays or ties without excessive compression and route away from sources of mechanical stress or sharp edges. For testing, use an optical power meter and light source or an optical loss test set to verify insertion loss and continuity.

Usage recommendations

Clean connector endfaces with appropriate fiber cleaning tools before each installation, avoid tight bends and kinks, and store spare cables coiled with a gentle radius. Use LSZH cabling in indoor public or confined spaces where reduced smoke and toxic emissions are required by regulation or site policy.
