What is OSNR in optical networks?

OSNR (Optical Signal-to-Noise Ratio) is a critical performance metric that measures the ratio of signal power to noise power, essential for link budget calculations and ensuring reliable high-speed optical transmission in DWDM systems.

What is DWDM technology?

DWDM (Dense Wavelength Division Multiplexing) combines multiple optical signals on different wavelengths onto a single fiber, enabling massive bandwidth expansion for metro networks, long-haul transmission, and data center interconnects.
