Feature
Copper telecommunication ducted cables (FSP-JF-LAP) are used for primary and secondary distribution networks, (i.e., in the secondary network between cross-connection cabinets and the subscribers’ connections, in the primary network between the exchange and cross-connection cabinets) and produced for ducted underground installation with black PE sheath it is suitable for tropical environmental conditions (from -10 °C to +60 °C).
Description
