Extralink Patchcord SC/APC-SC/UPC Single mode Simplex G652D 3mm 0.5m

The Extralink Patchcord SC/APC-SC/UPC Single mode Simplex G652D 3mm 0.5m is a single-mode fiber optic jumper designed for FTTH and short-distance optical connections. It uses G.652D single-mode fiber and comes terminated with an SC connector with APC polish on one end and an SC connector with UPC polish on the other, offering low insertion loss and stable optical performance. The compact 0.5 m length and approximately 3 mm jacket diameter make this patchcord suitable for patch panels, optical distribution frames and direct connections between active equipment.

Advantages

The patchcord provides consistent single-mode transmission characteristics of G.652D fiber and precise connector terminations to minimize back reflection and insertion loss. The SC/APC to SC/UPC combination supports connections where angled-polished connectors are required at one end to reduce return loss, while a UPC termination at the other end ensures compatibility with standard SC ports. The 3 mm jacket offers mechanical protection and ease of handling in rack and cabinet environments.

Suitable for

• FTTH installations and subscriber drop connections
• Connecting OLT to ONU/ONT devices
• Patching between switches, media converters and optical transceivers
• Patch panels and optical distribution frames in data closets

Key specifications

• Fiber type: single-mode G.652D
• Connector A: SC/APC (angled polish)
• Connector B: SC/UPC (ultra-polished)
• Configuration: simplex
• Cable outer diameter: approx. 3.0 mm
• Length: 0.5 m

How to use

Route the patchcord carefully to avoid sharp bends and excessive tension on the cable. Insert the SC/APC connector into the device or adapter requiring an angled-polish termination and the SC/UPC connector into the matching UPC-compatible port or adapter. Ensure connectors are clean and free of dust before mating to preserve low insertion loss and prevent damage to transceiver ports. When disconnecting, pull the connector body rather than the cable jacket.

Recommendations

For reliable performance, store and handle the patchcord in a clean environment, use appropriate dust caps when connectors are not in use, and follow standard fiber-cleaning procedures. Avoid tight bend radii and protect the cable during installation in racks or conduits to maintain optical performance and service life.
