Extralink SC/UPC‑SC/UPC Singlemode Simplex 3 mm Patch Cord, 10 m

Extralink Patchcord SC/UPC‑SC/UPC Singlemode Simplex 3 mm, 10 m is a singlemode fibre patch cable designed for optical network interconnections. The cable uses a G.657.A1 FTTH fibre with a 3 mm outer diameter and a 10 m length, terminated with SC/UPC connectors on both ends. The yellow jacket identifies it as singlemode and provides a visible, flexible link suitable for GPON/FTTH deployments, equipment connections and patch panel use.

Advantages

The patchcord offers low insertion loss and consistent return loss characteristics typical of SC/UPC terminations, ensuring reliable singlemode signal transmission. Its G.657.A1 fibre specification improves bend performance for installations with limited routing space. The 3 mm jacket balances flexibility and robustness for repeated handling and secure routing in racks or enclosures.

Suitable for

• GPON/FTTH subscriber connections between OLT and ONU/ONT devices
• Interconnection of optical equipment such as switches, media converters and optical transceivers
• Patch panel and splice enclosure patching in telecom and data centre racks
• Field or lab testing where a 10 m singlemode link is required

Key specifications

• Fibre type: Singlemode G.657.A1
• Connector type: SC/UPC to SC/UPC (simplex)
• Cable diameter: 3 mm
• Length: 10 m
• Jacket colour: Yellow
• Application: FTTH, GPON, optical equipment interconnects

How to use

Inspect connectors and ensure endfaces are clean before insertion. Route the patchcord along cable management paths avoiding tight bends and sharp edges; the G.657.A1 fibre tolerates tighter radii than standard singlemode but normal bend-radius practices should be observed. Align SC connectors with the corresponding SC sockets and insert until they click or seat firmly. When disconnecting, depress the connector latch and pull straight out; avoid twisting motions that could stress the fibre.

Recommendations

For optimal performance, clean connector endfaces with appropriate fibre cleaning tools prior to use and perform insertion-loss checks after installation. Store spare patchcords coiled loosely and protected from dust and mechanical damage. Use the 3 mm jacketed patchcord for general patching and the G.657.A1 fibre where routing requires tighter bends.
