Extralink fiber optic patchcord SC/APC–FC/UPC simplex G.657.A1 3.0 mm 2 m is a single-mode fiber jumper designed for FTTH and optical equipment interconnection. The cable uses bend-insensitive G.657.A1 fiber with a 3.0 mm outer jacket and a 2 meter length, terminated with an SC/APC connector on one end and an FC/UPC connector on the other. This patchcord provides a compact, low-loss connection for patch panels, optical line terminals and customer premises equipment where controlled attenuation and reliable single-mode performance are required.

Advantages

The use of G.657.A1 bend-insensitive single-mode fiber reduces macro-bend losses and improves signal stability in installations with tight routing and limited bend radius. The mixed connector configuration (SC/APC to FC/UPC) offers compatibility between different types of optical equipment while maintaining low insertion loss and return loss suitable for single-mode networks. The 3.0 mm jacket provides mechanical protection and handling ease during installation and maintenance.

Key specifications

How to use

Route the patchcord along the planned cable paths avoiding sharp bends and securing the cable with appropriate clamps or cable management elements. Insert the SC/APC connector into the corresponding SC/APC receptacle using the keyed housing to ensure correct orientation, then insert the FC/UPC connector into the FC port and secure it by threading the connector's ferrule sleeve as required. Verify optical continuity and signal levels with suitable test equipment after connection. Handle the fiber ends by keeping protective caps on until final insertion and avoid touching or contaminating connector end faces.

Recommendations

Store and transport the patchcord coiled without tight loops; maintain a bend radius according to G.657.A1 recommendations to preserve low-bend-loss performance. Clean connector end faces with appropriate fiber cleaning tools before mating. Use the SC/APC–FC/UPC patchcord in applications requiring compatibility between APC and UPC interfaces while monitoring return loss when connecting mixed-polish connectors.
