Siecor AFSV2S

The Siecor AFSV2S is a single-mode fiber optic cable designed for indoor premises applications. Built with tight-buffered construction, it delivers the flexibility and durability required for intra-building backbones, service entrances, and behind-the-shelf connectivity. The cable uses 900-micron tight-buffered fibers compliant with ITU-T G.652 D standards and is engineered to meet fire code provisions for indoor environments.
