The field service learns about transceivers, connector types and differences between PC, UPC, APC, EDFAs, fiber optic types, OTDR measurements and spectrum assessments and a troubleshooting guide.
For network operation there are detailed explanations of optical windows (O, E, S, C, L, U), fiber types G.652, G.652D, G.694, G.655, Ultra Low Loss Fiber, DCF as well as SFP, QSFP, OSFP. Signal modulation from NRZ to QAM is explained and signal propagation times as well as attenuation (dB) and level (dBm) are calculated.
For network management, alarms and their causes are highlighted, the OTN error cascade and working with AIS, BDI are explained and a strategy for error containment is given.For network planners there are calculations on optical budget, attenuation, span loss, dispersion and dispersion correction, optimization with fibre optics as well as network design and network protection. -
