Patchcord Extralink SC/APC–SC/APC, singlemode duplex G.657A1, 3 mm, 0,5 m

The Extralink SC/APC-SC/APC Single mode Duplex G.657A1 3mm 0.5m patchcord is a factory-terminated optical connection cable for single-mode networks. With SC/APC connectors on both ends and a 0.5 m length, this duplex cable supports full-duplex data transmission and is suitable for interconnecting networking equipment and FTTH components such as OLT and ONU/ONT devices.

Advantages

This patchcord uses G.657A1 single-mode fiber with a 3.0 mm jacket, providing good bend tolerance and compatibility with standard SC/APC interfaces. Factory-terminated SC/APC connectors ensure consistent insertion loss and return loss performance, while the duplex configuration enables simultaneous transmit and receive channels in a compact cable.

Suitable for

• FTTH installations (connecting OLT to ONU/ONT)
• Interconnection of switches, media converters and optical equipment
• Patching in fiber distribution frames and communication cabinets
• Short-distance fiber links within equipment racks or network closets

How to use

Uncoil the patchcord and align the SC/APC connectors with the mating adapters on the devices to be connected. Ensure connectors are clean and free of dust before insertion to minimise signal loss. Insert each SC/APC connector until it clicks into the adapter; the duplex cable will provide separate transmit and receive channels. Route the cable to avoid sharp bends and secure it to prevent strain at connector ends.

Recommendations

For optimal performance, clean connector endfaces with appropriate fiber cleaning tools before installation, avoid bending the cable below the recommended bend radius for G.657A1 fiber, and use dust caps when connectors are not mated. Verify link quality with an optical power meter or OTDR when commissioning critical links.
