Extralink Patchcord SC/APC-SC/APC Round drop single mode Simplex G.657A2 120m

The Extralink Patchcord SC/APC-SC/APC Round drop single mode Simplex G.657A2 120m is a single-mode fiber optic patch cable designed for FTTH and other fiber network installations. It features G.657A2 bend-insensitive fiber in a 3 mm round jacket and SC/APC connectors on both ends, providing reliable optical links for connecting optical line terminals (OLT), optical network units/terminals (ONU/ONT) and other fiber equipment over a 120‑metre run.

Advantages

This patchcord uses G.657A2 fiber which offers improved bend performance for installations in confined spaces and on routed drop lines. The SC/APC connectors ensure low return loss and stable mechanical mating for single-mode transmission. The 3 mm round construction balances flexibility with durability for indoor drop and horizontal cabling, while the 120 m length reduces the need for splices or additional couplers in medium-length premises runs.

Suitable for

• FTTH drop connections between OLT and ONU/ONT
• Horizontal and riser fiber runs in residential or small commercial buildings
• Interconnection of optical equipment such as switches, media converters and patch panels
• Installations requiring bend-insensitive fiber in tight routing spaces

Key specifications

• Fiber type: single-mode G.657A2 (bend-insensitive)
• Connector type: SC/APC to SC/APC, simplex
• Length: 120 m
• Cable diameter: 3 mm, round jacket
• Application: indoor drop, FTTH, horizontal cabling

How to use

Route the patchcord along the planned cable path avoiding sharp bends and mechanical stress. Insert the SC/APC connectors into compatible SC/APC adapter ports until they click or seat fully, ensuring connector keys and aperture orientation match the adapter. For FTTH installations, connect one end to the OLT or distribution point and the other to the ONU/ONT or terminal device. Secure excess length with gentle coils and use appropriate cable management to prevent kinks or compression.

Recommendations

Handle connectors by the housing and avoid touching the ferrule; clean connector end-faces before mating. Maintain minimum bend radius specified for G.657A2 fiber and protect the cable from tensile loads during installation. Store and transport the patchcord in a coiled configuration without tight loops to preserve optical performance.
