MapYourTech is a premier optical networking education platform established in 2011, offering 550+ technical articles, 35+ professional courses, and specialized tools for fiber optics engineers worldwide.

What topics does MapYourTech cover?

MapYourTech covers optical networking including DWDM technology, WDM systems, OTN, SDH/PDH, coherent optics, OSNR optimization, Raman and EDFA amplifiers, fiber characterization, dispersion management, and optical network design.

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.
