Patchcord Extralink SC/APC – LC/UPC Single Mode Duplex G.657.A1 3 mm, 5 m

Extralink SC/APC – LC/UPC single mode duplex patchcord with G.657.A1 fiber and 3 mm jacket diameter, 5 m length. This patchcord provides full-duplex optical transmission between devices with SC/APC and LC/UPC terminations and is optimized for FTTH deployments and indoor fiber connections. It is suitable for linking optical equipment such as ONT/ONU, OLT, media converters, switches and patch panels where a compact duplex single-mode cable with firm connector keying is required.

Advantages

The cable uses G.657.A1 single-mode fiber that offers improved bend performance for installations with tight routing requirements. With SC/APC on one end and LC/UPC on the other, the patchcord supports low-loss, polarization-stable connections and easy insertion into standard adapters and panels. The 3 mm jacket provides mechanical protection while remaining flexible for indoor routing, and the 5 m length covers typical rack-to-equipment and wall-to-equipment distances without excess slack.

Suitable for

• FTTH subscriber connections between OLT/ONT or ONU devices
• Interconnection of patch panels, fiber distribution frames and wall outlets
• Linking media converters, switches and optical transceivers in indoor racks
• Deployments requiring improved bend performance in residential or commercial premises

Key specifications

• Fiber type: G.657.A1 single-mode
• Connector A: SC/APC (angled physical contact, green ferrule)
• Connector B: LC/UPC (ultra physical contact, blue ferrule)
• Configuration: Duplex (two fibers)
• Cable jacket diameter: 3 mm
• Cable length: 5 m
• Application: Indoor/FTTH optical patching and equipment interconnection

How to use

Route the patchcord along cable trays or behind equipment racks, avoiding sharp bends and pinch points. Align the SC/APC and LC/UPC connectors with their respective adapters or ports and insert them until they click or seat firmly. Ensure the connectors are clean before insertion by inspecting or using appropriate fiber cleaning tools; contamination can cause increased insertion loss. For duplex connections observe correct polarity so transmit and receive fibers match the corresponding ports on both ends.

Recommendations

Store the patchcord coiled loosely to prevent kinks. Maintain a minimum bend radius consistent with G.657.A1 specifications when routing (avoid tight wraps around small radii). Clean connectors with lint-free wipes or fiber cleaning tools before connecting and use dust caps when not in use to protect connector end faces.
