Ideal single mode laser operation with single drive conventional/phase shift Mach–Zehnder modulators measured in optical access networks

This study reported the performance evaluation and simulation of passive optical networks for high transmission rates up to 10 Gb/s for possible distance up to 50 km. Laser rate equations, directly modulated laser measured and vertical cavity surface emitting laser (VCSEL) are employed for the measurement of the network performance. Different bit sequences are suggested to show the network performance parameters with various proposed optical sources. Optical and electrical powers are measured for 50 km network reach. In addition to max. Q factor is also measured for various optical sources and bits sequence variations. Laser rate equations are employed in this network to upgrade the Q factor criteria for maximum network reach of 100 km in the downstream direction.

This paper has clarified the gallium aluminum arsenide and plastic modulators and its element circuit modeling design considerations for high signal processing distance links communications. Modulator circuit model design considerations and equations analysis are taken into account. Modulator source resistance, modulator inductance, and modulator capacitance based electro-optic modulator (EOM) is studied and analyzed against temperature variations. In addition to the switching voltage for EOM is analyzed at both 1300 nm and 1550 nm wavelength versus temperature variations. The operation efficiency and maximum modulation resonance frequency are studied for previous and proposed EOM versus modulator length variations. The lower modulator resistance, modulator capacitance, and modulator inductance can be achieved with the proposed EOM. As well as the proposed EOM has outlined the optimum operational efficiency and maximum resonance modulation frequency compared to the previous EOM.

The optical add drop multiplexers (OADMs) to be modeled and analyzed depends up on the simulation variables are demonstrated. Transmitted power per channel variations are studied against both fiber length and number of transmitted channels at receiver bandwidth of 40 GHz and temperature of 25 °C. Received power from each channel variations are demonstrated against both fiber length and number of transmitted channels at receiver bandwidth of 40 GHz and temperature of 25 °C. The bit error rate variations are clarified against both fiber length and number of transmitted channels at receiver bandwidth of 40 GHz and temperature of 25 °C. The optical link map through fiber cable core is clarified. Total pulse broadening variations are illustrated against both fiber length and number of transmitted channels at receiver bandwidth of 40 GHz and temperature of 25 °C. The lighted signal/noise ratio variations are demonstrated against both receiver bandwidth and number of transmitted channels at transmission distance of 200 km and temperature of 25 °C. Channel capacity variations are also demonstrated against both receiver bandwidth and number of transmitted channels at transmission distance of 200 km and temperature of 25 °C.
