Extralink patchkabel LC/UPC-LC/UPC singlemode simplex G657A1 3mm 1m

The Extralink Patchcord LC/UPC-LC/UPC Single Mode Simplex G657A1 3mm 1m is a 1-meter single-mode fiber optic patch cord terminated with LC/UPC connectors on both ends. Built with G.657.A1 bend-insensitive fiber and a 3 mm jacket, the patchcord is intended for short interconnections between optical equipment such as switches, media converters, patch panels and FTTH customer premises devices. The cable design balances flexibility and mechanical protection to suit both rack-mounted and wall-mounted installations.

Advantages

This patchcord uses G.657.A1 single-mode fiber to reduce bend sensitivity and maintain low insertion loss in tight routing conditions. The LC/UPC connector interface provides a standardized, compact plug compatible with common networking ports. With a 3 mm outer diameter, the cable offers improved handling and greater durability compared with thinner jumper cables while remaining flexible enough for typical installation pathways.

Suitable for

• Interconnection between switches, media converters and optical transceivers
• FTTH link between OLT and ONU/ONT devices in customer premises
• Patch panel to network equipment connections in data cabinets
• Short-distance fiber runs in telecom rooms and small network closets

Key specifications

• Fiber type: Single-mode G.657.A1 (bend-insensitive)
• Connector type: LC/UPC on both ends (simplex)
• Cable construction: Simplex, tight-buffered
• Outer diameter: 3.0 mm
• Length: 1 meter
• Typical use: Indoor patching and short interconnects

How to use

Identify the LC ports on the devices to be connected and ensure both ends are clean and free of dust. Insert each LC/UPC connector into the corresponding port until it clicks into place. Route the cable without sharp bends and avoid compressing it under heavy panels or cable ties. For removal, depress the connector latch and pull gently. Regularly inspect connector endfaces and clean with appropriate fiber cleaning tools if optical performance appears degraded.

Recommendations

Use this 1 m LC/UPC-LC/UPC patchcord for short internal links where single-mode performance and bend resistance are required. Store spare jumpers in protective pouches, avoid bending radii below the manufacturer's guidelines, and clean connectors before mating to maintain optimal signal quality.
