The ITU Radiocommunication Assembly considering a) that the World Administrative Radio Conference For Dealing With Frequency Allocations in Certain Parts of the Spectrum (Málaga-Torremolinos, 1992) (WARC-92) adopted primary mobile-satellite service (MSS) allocations in the 1 to 3 GHz frequency range on a shared primary basis with other radio services subject to coordination in accordance with Resolution 46; b) that there are other MSS allocations; c) that non-geostationary satellite orbit (non-GSO) networks implementing these MSS allocations may use the fixed-satellite service (FSS) allocations for feeder links; d) that the feeder links for these MSS non-GSO networks are considered part of the FSS; e) that the frequency and technical characteristics of such feeder links for the non-GSO MSS networks may depend on the technical characteristics of such systems using the MSS frequency bands; f) that several of these non-GSO MSS networks may use the same FSS frequency band for their feeder links; g) that studies of interference mechanisms between non-GSO networks in the respective MSS and the FSS allocated bands have commenced but are not complete; h) that the permissible interference criteria used for geostationary FSS networks may not be applicable to the FSS feeder links for non-GSO MSS networks.

ITU-T HDBK PTL CHAPTERS 9 AND 10-1995 电信线路的保护和雷电放电装置第9和10章

An optical fiber cable which has metallic components,either in the sheath or in the core,is susceptible to lightningdamage.The reasons for having metallic components may be to provide tensile strength,moisture barriers, rodentprotection andor communication (“talk-pair”) facilities. Cable locating for maintenance and repair activities is alsofacilitatedby metal in the cable.The fact that lightningcan damage fibers in such cables has been evidenced in the fieldand in lightning simulationexperiments [I].This methodology provides two numerical approaches to estimating the primary damage rate.Primary damage refers to instances where the fiber is out of service.The result yielded by the first assessment technique is useful for comparison purposes whether various route designsor cable designs are being evaluated. It may also be used when an absolute value is needed.The result yielded by the second assessment technique may be used when a conservative value for Annual Damage Rate is needed, or for comparative studies.Work is currently under way to study the actual field damage rates and compare them to the calculatedrates.Secondary damage, for instance pinholing which may increase the corrosion rate,can be evaluated by means of the formulas given in Appendix 5 of Chapter 7,or by the algorithmspresented in [5].Any lightning damage mitigation technique,e.g. route redundancy, shield wires,more rugged cable, etc.should only be considered in cases where the lightning damage rate is significant in comparison to other sources of cable damage,e.g. cable cuts.Improvement in the overall system availabilitycan be calculatedusing the methods given.
