IPLC costing Local Backhaul Wet Segment Cost Distant Backhaul Cost IPLC cost has 3(three) / 4(four) cost segment Total cost = Backhaul cost at local end + wet-segment (through SMW4 submarine cable, under the sea) or satellite segment cost (half or full circuit) + backhaul cost at the distant end. At present IPLC through SMW4 submarine cable is more popular than that of Satellite as the cost through submarine is much more cheaper.
