TeraSpan’s Vertical Deflecting Conduit (VDC) is a two-part conduit system that zips together to encase cables, blow tubes, or a pull string. The VDC1 FD is designed specifically to accommodate a flat aerial drop style cable.


VDC houses and protects cables or blow tubes in installations of the VIF system, in both soft and hard infrastructures. The conduit is ideal for FTTH and FTTB drops using flat aerial drop cable.
