C.O.D. stands for Corrugated Optic Duct, the registered brand of our product, with built-in multiple cable ducts inside of outer duct as an integrated single body. Optiroad COD has very distinctive differences from the conventional telecommunication PVC ducting System.Optiroad C.O.D. opens new era of telecommunication backbone with its built-in multiple inner ducts (3 to 5) inside of the outer duct by means of assembling cable ducts in the course of production. Both inner and outer ducts are made of HDPE (High Density Polyethylene) having high flexibility enabling rolled-on spool regardless of numbers of inner ducts built-in.Coiling Length of C.O.D. is unlimited, however depending on the numbers of inner ducts and diameters 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 quick installation reducing considerable consecutive work quantities such as trench excavation, inner duct insertion (no need as it is readily built-in), inner duct related works (such as cleaning of duct line upon completion of outer duct connection and inspection thereof) and installation time.
Owing to such benefits, great savings of project cost as well as traffic trouble are anticipated contributing to the construction of telecommunication infrastructure.

Products – what should be COD

As you already browsed finding lots of benefits of our innovative products, COD, as well as the potential applications of our COD, we are confident that you would feel that it could meet your entire requirement to your satisfaction.

dimension & shipping information

You can compare COD, the innovated technology, to the conventional PVC ducting system being applied in many job sites in your area, Firstly: Both inner ducts and outer duct of COD are made of HDPE with the same raw material, which is distinctive physical.

Characteristics compare to the conventional PVC ducting system being two different raw materials (PVC for outer duct and PE for inner ducts). Owing to the high density but light, and stronger compressive load (+292kgf/㎠) than that of conventional ducting system, it also provides much less restrictions in installation specifications.Secondly: The length of COD may vary to meet customer's requirement even up to 1,000 meters depending on the model of COD.

It enables installation in-between two manholes without any connection but in a single piece. In addition, the flexibility of COD allows to pass-by or over-pass hurdles along trench without any special bending like PVC ducting system.Thirdly: Owing to a single laying of COD without connection, there's no risk of air or water leakage at all. Even connection is being required, the perfect coupling system provide perfect waterproofing and air sealing.Finally: The innovative product of COD declares no insertion of inner ducts are required at all as they are readily built-in.Depending on country, labor cost of the inserting inner ducts may cost higher than material cost of both outer duct and inner ducts.One of the candid merits out of COD is the inner ducts are perfectly aligned as straight as outer duct without allowing any tangle or twist inside of outer duct, which allows easy insertion of cable even without pre-lubrication or silicon coating inside of inner ducts. Such a straight line-up may save as much as 5% of expensive fiber optic cable.
