Requirements for Aerial Optical Cables Crossing Highways
163 describes criteria for the installation of optical fibre cables defined in Recommendation ITU-T L. 110 in remote areas with lack of usual infrastructure for installation including the procedures of cable-route planning, cable selection, cable-installation. This good practice guide is aimed at highway authorities and those organisations that need to carry out street works using licences issued under section 50 of the New Roads and Street Works Act 1991 (NRSWA). FO-VC2 JOINT USE - VERICAL MIDSPAN CLEARANCES 48. APPENDIX A - COVER SHEET / TOC 52. RUS.
