Both innerand outer pipe are made of HDPE (High Density Polyethylene). It is flexible andcan be coiled over 500m. That means COD (corrugated optic duct) is possible toeasy transport and reduces labor cost. This can be fast installation and downthe constructions cost.
CoilingLength of COD is unlimited, however depending on the numbers of inner ducts anddiameters thereof; each reel may practically coiled up to 500 meters, however,coiling even 1,000 meters of small dimension model is also available.
Owing to such a flexible and lengthy product of COD, it enables quickinstallation reducing considerable consecutive work quantities such as trenchexcavation, inner duct insertion (no need as it is readily built-in), inner ductrelated works (such as cleaning of duct line upon completion of outer ductconnection and inspection thereof) and installation time.
Owing to suchbenefits, great savings of project cost as well as traffic trouble areanticipated contributing to the construction of telecommunicationinfrastructure.

COD(corrugated optic duct) was proven their great economics and convenientinstallation than any other system by all of telecommunicationcompanies.
