Attenuator Fiber Optics

Attenuator Fiber Optics

An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

Third-generation semiconductor optical module

Third-generation semiconductor optical module

Key features include enhanced thermal management for reliable high-power operation and cost-effective manufacturing through scalable panel-level designs. (NASDAQ: AVGO) today announced significant advancements in its co-packaged optics (CPO) technology with the launch of its third-generation 200G per lane (200G/lane) CPO product line. Compared with the first generation semiconductor material of silicon (Si) and the second generation semiconductor material of gallium arsenide (GaAs), the third generation semiconductor material (also referred to as wide bandgap semiconductor material) of silicon carbide (SiC) or gallium nitride. The third-generation semiconductors, such as silicon carbide and gallium nitride, possess superior properties such as wide bandwidth, high efficiency, remarkable electricity resistance, power handling capacity, heat tolerance, and radiation resistance.
