Patchcord Extralink SC/APC - LC/UPC Singlemode Duplex G.657.A1 3mm 1m

Patchcord Extralink SC/APC - LC/UPC singlemode duplex G.657.A1 3mm 1m is a single-mode duplex optical patch cable designed for FTTH and other fiber-optic link applications. The cable uses bend-insensitive G.657.A1 fibre inside a 3 mm yellow jacket and provides a compact connection with SC/APC on one end and LC/UPC on the other. With a 1 m length and full-duplex terminations, this patchcord is intended for short interconnects between optical equipment, patch panels and customer-premises devices.

Advantages

The Extralink patchcord combines bend-insensitive G.657.A1 fibre with standard SC/APC and LC/UPC connector geometries to maintain low insertion loss and stable return loss in typical FTTH environments. Its 3 mm jacket offers easy handling and routing while preserving fiber protection. Duplex configuration supports simultaneous transmit and receive channels, and the colour-coded yellow jacket enables quick identification of single-mode links.

Suitable for

• FTTH drop and indoor customer connections
• Patch panels and optical distribution frames
• Connecting OLT, ONU/ONT and optical transceivers
• Short patching runs in telecom rooms and equipment racks

Key specifications

• Fibre type: Single-mode, bend-insensitive G.657.A1
• Jacket diameter: 3 mm
• Length: 1 m
• Connector configuration: Duplex (two fibres)
• Connector A: SC/APC (angled physical contact, APC)
• Connector B: LC/UPC (ultra physical contact, UPC)
• Jacket colour: Yellow (single-mode identification)

How to use

Route the patchcord from the source equipment to the target device avoiding sharp bends and tight loops. Ensure connectors are clean before insertion to protect transceiver interfaces; use dust caps until installation. Insert the SC/APC and LC/UPC connectors into the corresponding adapter or transceiver ports until a secure fit is felt. For duplex operation, observe transmit/receive orientation to match the link wiring. When routing inside panels or racks, secure the cable with gentle clips or ties to prevent strain on connectors.

Recommendations

Inspect and clean ferrules before each connection, maintain minimum bend radius recommended for G.657.A1 fibre, and avoid pulling on the jacket near the connector during installation. Store unused patchcords with protective caps in a dry, dust-free environment.
