Fiber patchcord Extralink SC/APC to LC/UPC, Singlemode G.657.A1, 3 mm, 2 m, simplex

Fiber patchcord Extralink SC/APC to LC/UPC, Singlemode G.657.A1, 3 mm, 2 m, simplex is a singlemode jumper designed for optical network interconnections. The cable combines an SC/APC connector on one end and an LC/UPC connector on the other, offering a compact simplex link for patch panels, ONUs/ONTs and active equipment in telecom racks and data centres. The G.657.A1 bend-insensitive fibre and a 3 mm outer jacket provide reliable signal transmission and flexible routing in confined installations.

Advantages

This patchcord uses singlemode G.657.A1 fibre that reduces sensitivity to tight bends, supporting stable performance in FTTH and indoor distribution scenarios. The mixed connector combination (SC/APC to LC/UPC) allows direct connection between equipment with different interface types without additional adapters. A 2 m length and 3 mm jacket make the cable easy to handle and route while preserving mechanical protection for everyday use.

Suitable for

• FTTH termination between OLT and ONU/ONT devices
• Patching in optical distribution frames and wall-mounted termination panels
• Interconnection between switches, media converters and optical transceivers
• Laboratory and field testing where a short, reliable singlemode link is required

Key specifications

• Fiber type: singlemode, ITU-T G.657.A1 bend-insensitive
• Connector A: SC/APC (angled physical contact, green boot)
• Connector B: LC/UPC (ultra-physical contact, blue boot)
• Cable construction: simplex, 3 mm outer jacket diameter
• Length: 2 metres
• Application: indoor, patching and equipment interconnects

How to use

Inspect both connectors and mating adapters for dust or damage before insertion. Align the keyed SC/APC and LC/UPC connectors with the respective ports and insert until a positive click or secure seating is achieved. Avoid bending the cable below the minimum bend radius recommended for G.657.A1 fibres and secure the cable to prevent strain on connectors. When disconnecting, pull by the connector housing rather than the fiber jacket to protect the termination.

Recommendations

Use a dust cap on unused connectors and, if available, a fibre inspection microscope to verify endface cleanliness. For installations in cabinets or behind equipment, route the patchcord with gentle curves and use cable management panels or clips to maintain bend radius and reduce mechanical stress.
