III: FOC NETWORK ENGINEERING REQUIREMENTS FOR PERMIT APPLICATION III. 1: Design stages and submissions III.1.1: Permit applicant requirement during design stage a. A physical pre-survey of the route for all types of installations for the purpose of establishing the exact cable routing, termination points, jointing locations and cutting lengths will be done before the commencement of any work or committing any materials. If a change in route is required for any practical reason, prior approval should be obtained from the regulatory authority. b. Optical power link loss budget shall be calculated for any FOC link. Parameters to be included in calculation of link losses are specified in appendix2. c. The maximum length of any optical path between two fibre optic repeaters must be calculated separately, and depends on the total loss in all components used in the path, including fibre optic cable, optical connectors, star couplers, and splices. d. All components such as additional connectors, star couplers and splices along with cable attenuation, should be taken into account in calculating the loss. e. The sum of the losses in all components used in the optical path must not exceed the specified Power Loss Budget for the chosen cable type. f. The specified Power Loss Budget includes the loss of the two ST–type connectors connecting at the two repeater ends, and also includes the system margin of 3 dB. III.1.2: Plan documents Plan document should include : 1) One original complete copy of the plans showing the proposed work, schedule and procedures. However an additional copy will be required if there is a bridge attachment, road crossing, box culvert crossing, limited access or inter-district involved; 2) The route/ street name/ location where the work is to be performed; 3) Color highlights to show the demanded right-of-way (red) and the existing cable (blue); 4
