Telecommunications fiber optic cable conduit diameter
Optical cable is usually placed in a 25 to 40 mm inside diameter (ID) sub-duct which is placed into an existing larger diameter communications conduit. Example: To arrive at a working bend radius for cable installation, multiply 15 times (15 x) the cable outside diameter. The size of conduit you should use depends on the type of fiber optic assembly and the number of cables it will house. Our comprehensive chart simplifies the process by outlining the key dimensions—core size, cladding size, coating diameter, and buffer size—that technicians, engineers, and buyers need to evaluate. Underground cables are pulled in conduit that is buried underground, usually 1-1.
