What does uw represent in an optical power meter
Optical power is measured in linear units of milliwatts (mW), microwatts (uW - really the greek letter "mu"W), nanowatts (nW) and decibels (dB). What is the difference between "dBm" and "dB"? dB is a ratio of two powers, for example the loss in a fiber optic cable. In essence, it helps engineers and technicians assess the fiber optic link's quality by measuring the light's signal strength in microwatts. An optical power meter (OPM) is a device used to measure the power in an optical signal.

Does computing power benefit optical modules
CPO optical modules put optical and electronic parts together. They make the signal path much shorter, from centimeters to millimeters. This can cut power use by up to half. CPO technology lets more data fit in. The explosive growth of Artificial Intelligence (AI) workloads is fundamentally reshaping the requirements for data center infrastructure. Next-generation AI clusters demand dramatically higher bandwidth density, improved thermal management, and greater system-level reliability than traditional. In this scenario, Co-Packaged Optics (CPO) is now gaining momentum, emerging mainly as an alternative to the pluggable optical modules traditionally employed in networking switches (“scale-out” datacenter expansion). By integrating an electrical die and a silicon photonics die in the same package. A recent study by Resolute Photonics highlights the dramatic differences in energy consumption per bit across different optical interconnect architectures. Traditional Front Plate Pluggable (FPP) Optics are increasingly challenged to meet the demands for higher bandwidth and energy efficiency.
