About this file
This technical guide document, issued by the Connecticut Department of Transportation, provides detailed installation specifications for fiber optic communication conduit systems as part of the Rehabilitation of Bridge No. 00196 (Interstate 95 over U.S. Route 1) in Branford, Connecticut, identified as Project No. 0014-0185. The document includes comprehensive technical drawings and installation details for multiple components of the fiber optic infrastructure, including conduit crossing specifications under roadways and existing utilities, guide rail crossings, pullbox and handhole installations, and conduit treatment at sign supports. The specifications detail minimum installation depths of 40 inches for conduit, minimum bend radius requirements of 22.5 to 48 inches for rigid metal conduit, and restoration requirements for areas disturbed during trenching operations. The contractor is responsible for ensuring that all conduit installations do not conflict with underground utilities and must contact the Call Before You Dig hotline (1-860-594-3447) prior to excavation.
The document establishes detailed specifications for both underground and aerial fiber optic cable installations, including wood pole and utility pole configurations with specific measurements for messenger support, cable lashing clamps, splice cases, and clearance requirements. Aerial installations must maintain minimum clearances of at least 40 inches below the lowest power company attachment and at least 12 inches above the highest test communications utility attachment. The specifications require contractors to store nominal 75 to 100 feet of extra fiber length at splice enclosures and maintain the manufacturer's minimum bend radius for all fiber optic cable bends. Warning tape and identification posts with reflectorized orange signage must be installed in areas where fiber optic conduit is buried below ground to alert excavators and construction personnel to the presence of underground communication infrastructure.
