Course Content (Syllabus)
Theory: Basic analog-digital signal concepts, configuration ON / OFF, phase modulation, sampling, NRZ-RZ data transmission rate, explanationof the importance of FOURIER (WITHOUT MATHEMATICS), optical multiplexing techniques (WDM-TDM). Basic wave concepts (amplitude + phase), interference, diffraction, group velocity, phase velocity, refractive index. Optical fiber and attenuation, Db-dBm units. Dispersion, attenuation and dispersion exercises. Passive devices (filters-COUPLERS-SPLITTERS-MUX-DEMUX-OPTICAL ADD / DROP MULTIPLEXERS, RECONFIGURABLE OPTICAL ADD / DROP MULTIPLEXERS). Modern optical PON (GPON-XGPON-NGPON-WDMPON-TDMPON-TWDMPON) and devices, protocols and operation of an optical PON.
Lab: Introduction to SIMULINK, download a version of matlab in pc of caclab. Using SIMULINK the student will perform the following exercises: (i) GAUSS and Square Pulse, time + spectrum, for various Dt and Df, inverse relationship between time-spectrum, (ii) periodic signal in time and spectrum, signals with two periods, pseudorandom bit sequences, calculation of the signal energy in time and spectrum. (iii) Optical fiber losses, measurements of different fiber lengths and different loss factors (SMF& NZ-DSF), peak power measurements at the output, average power at the output, spectrum observation, familiarization with units dB-dBm. (iv) phase of optical signals (phase-time relation), dispersion theory, dispersion exercises. (v) Dispersion in gaussian pulse, theory of gaussian pulse, chirp, transform limited pulse. (vi) Examples for gaussian pulse dispersion without initial chirp, expanded pulse curves. (vii) examples for dispersive pulses with initial chirp, (viii) complete dispersion compensation using SMF + DCF. (ix) non-complete dispersion compensation using SMF + NZ-DSF fibers, (x) design of a Passive Optical Network (PON) for access.
