Patchcord Extralink LC/UPC – LC/UPC Duplex, Singlemode G657A1, 3 mm, 5 m

Extralink LC/UPC - LC/UPC Duplex singlemode patchcord, 5 m length with a 3 mm jacket, uses G657A1 fiber designed for improved bend performance. The cable features LC/UPC connectors on both ends in a duplex configuration to support two independent optical channels. This patchcord is intended for reliable low-loss connections in optical patch panels, telecommunications racks, FTTH installations and data center environments where space and signal integrity are important.

Advantages

The G657A1 fiber construction provides enhanced bend tolerance compared with standard singlemode fibers, reducing signal degradation in constrained routing scenarios. LC/UPC duplex connectors ensure compact, standardized interfacing with LC ports and minimize insertion loss for stable optical transmission. The 3 mm jacket balances flexibility and mechanical protection for routine handling and patch panel installations.

Suitable for

• Patch panels and fiber distribution frames in data centers
• FTTH drop and subscriber connections where bend performance matters
• Telecommunications equipment interconnects and cabinet wiring
• LAN backbone and fiber patching between network devices

Key specifications

• Fiber type: singlemode G657A1 (improved bend performance)
• Connector type: LC/UPC to LC/UPC duplex
• Cable jacket diameter: 3 mm
• Length: 5 m
• Configuration: duplex (two fibers in parallel)
• Typical performance: low insertion loss, stable duplex transmission

How to use

Route the patchcord from one LC duplex port to the corresponding LC duplex port on the destination device or panel, avoiding sharp bends and excessive pulling. Insert LC/UPC connectors straight into the LC adapter until they click to ensure secure mating. When removing the patchcord, press the connector latch and pull straight out. For installation in patch panels, lay the cable into cable management guides or rings and secure excess length to prevent strain on connectors.

Recommendations

Avoid bending the cable below the recommended minimum bend radius for G657A1 fiber and keep connectors capped when not in use to prevent contamination. Use proper fiber cleaning procedures for the LC/UPC end faces before mating to maintain low insertion loss and reliable performance.
