Developments in Time-Division Multiplexing of X-ray Transition-Edge Sensors

Wavelength Division Multiplexing: An Overview & Recent Developments

As speed & bandwidth has always been a cause of concern in communication network, WDM emerges as a vital solution to these problems. The problem arises when the demand for bandwidth in a fiber optic network exceeds the current capacity, WDM helps in expanding the capacity of a fiber optic network without requiring additional fiber. The decision problem is to find the most cost-effective combina...

Fine-Grain Time Division Multiplexing in FPGAs

Increase in FPGA capacity combined with CMOS technology scaling has resulted in increased demands on the configurable wiring architecture. Modern FPGAs typically give over 50% of the reconfigurable area over to routing resources. Rent’s Rule [1,2] implies that static FPGA wiring is not scalable and we are approaching the point where cross chip communication is impossible within a clock cycle. I...

Remote-Time Division Multiplexing of Bending Sensors Using a Broadband Light Source

This work experimentally demonstrates a remote sensing network which interrogates bending sensors using time-division multiplexing techniques and a broadband light source. The bending sensors are located 50 km away from the monitoring station. They are based on a simple tie displacement sensor and offer high-resolution measurements of displacement.

Time domain multiplexed spatial division multiplexing receiver.

A novel time domain multiplexed (TDM) spatial division multiplexing (SDM) receiver which allows for the reception of >1 dual polarization mode with a single coherent receiver, and corresponding 4-port oscilloscope, is experimentally demonstrated. Received by two coherent receivers and respective 4-port oscilloscopes, a 3 mode transmission of 28GBaud QPSK, 8, 16, and 32QAM over 41.7km of few-mod...
