Optical patch cable LC/UPC to LC/APC duplex singlemode 1 m, LC/U/LC/A-DX-1.0

Duplex singlemode optical patch cable LC/UPC to LC/APC duplex singlemode 1 m, LC/U/LC/A-DX-1.0 is a 1‑metre fiber patch cord that connects equipment with LC/UPC and LC/APC interfaces. The cable combines a UPC polished connector on one end and an APC polished connector on the other, enabling mixed‑endface links where low insertion loss and high return loss on the APC side are required. It is built for singlemode transmission and intended for point‑to‑point connections in telecom, data centre and laboratory environments.

Advantages

This duplex singlemode patch cable provides stable optical performance with low attenuation and consistent mating quality. The LC/UPC to LC/APC pairing reduces back reflection on the APC side while maintaining compatibility with UPC interfaces. Its duplex construction supports bidirectional signal paths and simplifies fiber management. The short 1 m length minimizes excess slack in rack‑mounted or bench setups.

Suitable for

• Connecting singlemode transceivers and patch panels with mixed LC/UPC and LC/APC ports
• Data centres and telecom racks where APC return‑loss performance is required
• Laboratory testing, measurement and temporary interconnections
• Optical equipment setups that require duplex fiber links with minimal length

Key specifications

• Fiber type: singlemode (OS2/ITU‑T G.652 compliant typical)
• Connector A: LC with UPC polish
• Connector B: LC with APC polish
• Configuration: duplex (2 fibres)
• Length: 1 m
• Typical insertion loss: low (industry standard values for LC singlemode duplex)
• Return loss: high on APC end (improved back‑reflection performance)
• Jacket: flexible, suitable for rack and patch panel use

How to use

Insert the LC/UPC connector into the corresponding UPC port and the LC/APC connector into the APC port, ensuring proper alignment of the duplex clip orientation. Route the cable to avoid tight bends and secure it in cable management channels or ties to prevent strain on the connectors. Verify optical link integrity with a power meter or transceiver diagnostics after installation.

Usage recommendations

Handle connectors by the boot and ferrule area, keep protective caps on unused connectors, and avoid bending radii below the fibre specification. Use this LC/UPC to LC/APC duplex singlemode cable when mixed polish types are required; confirm port polish types before connecting to prevent mismatched mating that can increase loss or reflections.
