... transmission through the various media. The laboratory experiment used a subscale, filtered, and attenuated 5 mW blue-green laser in a 22-meter folded path configuration to demonstrate real-time data transmission at 312 Megabit per Second (Mbps) data rate using single channel Quadrature Phase Shift Keying...

... of penetration (ROP) and log density, the real-time data rate has to increase. This is particularly true when demanding mud environments create demanding transmission conditions for MPT. As the well depth increases, it affects the mud density and mud plastic viscosity, making the situation even more challenging...

... integrity and safety, for the severe EMI environments created where motors and power cables are used. The system uses conventional optical fibre conductors with 1550 nm laser generated optical pulses as the information carrier. Data rates of 2.0 Mbs-i are achievable, unrepealed, over distances in excess...
