Patchkabel Extralink SC/APC naar LC/UPC, singlemode duplex G.652D, 3 mm, 20 m

Patchcord Extralink SC/APC to LC/UPC, Single-Mode Duplex G.652D, 3 mm, 20 m is a factory-terminated duplex single-mode fibre patchcord designed for point-to-point optical links. It combines an SC/APC connector on one end with an LC/UPC connector on the other, uses G.652D single-mode fibre and is built in a 3.0 mmrounded cable suitable for FTTH-style installations. The 20 m length provides flexibility for connecting equipment across racks, cabinets and premises while preserving optical performance for long-reach and metro applications.

Advantages

This patchcord provides low-loss, polarity-specific duplex transmission between devices with APC and UPC terminations, reducing back-reflection where required by optical systems. The use of G.652D single-mode fibre ensures standardised attenuation and dispersion characteristics suitable for most telecom and data applications. The 3 mm jacket offers mechanical robustness and easier handling during installation compared with thinner indoor fibres, while pre-terminated connectors minimise field termination time and potential connection variability.

Suitable for

• Interconnecting optical equipment such as switches, media converters and transceivers
• Patching between splice cabinets, distribution frames and patch panels
• FTTH indoor connections between OLT and ONU/ONT or residential termination points
• Laboratory testing and temporary links where mixed APC/UPC terminations are required

Key specifications

• Fibre type: single-mode G.652D
• Configuration: duplex (two fibres)
• Connector A: SC/APC (angled physical contact)
• Connector B: LC/UPC (ultra-physical contact)
• Cable diameter: 3.0 mm round jacket
• Length: 20 m
• Typical application: indoor FTTH, rack-to-rack and cabinet interconnects

How to use

Inspect both connectors and mating adapters for dust or damage before insertion. Ensure patchcord polarity matches the transmit/receive pairing required by your equipment. Gently insert the SC/APC connector into the corresponding adapter until it seats, observing the angled ferrule orientation to maintain APC performance. Insert the LC/UPC connector into the LC adapter until it latches; avoid excessive force. Route the 3 mm cable to prevent sharp bends and secure it with appropriate cable management to avoid strain on the connectors.

Recommendations

Store and transport the patchcord coiled without tight loops; maintain a bend radius in accordance with common single-mode indoor fibres (avoid bends below 30 mm). Clean connector end-faces with suitable fibre cleaning tools before every connection to maintain low insertion loss. Use APC-to-UPC mating only where specified by system requirements and verify optical power and return loss after installation.
