 As electrical engineers, OSP engineers are responsible for the resistance, capacitance, and inductance (RCL) design of all new plant to ensure telephone service is clear and crisp and data service is clean as well as reliable.Attenuation or gradual loss in intensity and loop loss calculations are required to determine cable length and size required to provide the service called for.In addition power requirements have to be calculated and provided to power any electronic equipment being placed in the field.
