Electronic Distance Measuring Instruments

21
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short...

Bus Impedance Matrix

Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

    Area of Science:

    • Photonics and Optical Communications
    • Integrated Photonics
    • High-Speed Data Transmission

    Background:

    • Artificial intelligence (AI) clusters and computing networks require low-power, low-latency optical interconnects for effective scaling.
    • Traditional intensity modulation with direct detection (IM/DD) optical interconnects heavily depend on digital signal processing (DSP), increasing power consumption and latency.

    Purpose of the Study:

    • To compare the performance of linear receive optics (LRO) against fully DSP solutions using a broadband thin-film lithium niobate (TFLN) Mach-Zehnder modulator (MZM) chip.
    • To demonstrate reduced power consumption and latency in optical interconnects by minimizing receiver-side DSP.

    Main Methods:

    • Utilized a broadband thin-film lithium niobate (TFLN) Mach-Zehnder modulator (MZM) chip.
    • Compared performance metrics between LRO and fully DSP-based optical interconnect solutions.
    • Evaluated bit-error rates (BERs) against forward error correction (FEC) thresholds.

    Main Results:

    • Achieved generation of 154 GBd PAM4 and 190 GBd OOK signals with BERs below the KP4-FEC threshold.
    • Successfully transmitted 182 GBd PAM4 over 150m of single-mode fiber.
    • Generated a 196 GBd OOK signal with BER below the 20% soft-decision forward error correction (SD-FEC) threshold, eliminating receiver-side equalization DSP.

    Conclusions:

    • The TFLN MZM chip enables optical interconnects with drastically reduced power consumption and latency.
    • Eliminating receiver-side equalization DSP while maintaining high-bandwidth performance ensures broad interoperability for future computing networks.
