In today's dynamic business landscape, organizations across the Asia-Pacific (APAC) region are searching innovative solutions to optimize their operational efficiency and drive growth. Software-defined Wide Area Network (SD-WAN) has emerged as a transformative technology, offering unprecedented flexibility, scalability, and performance advantages.

Wavelength Division Multiplexing (WDM) is a essential technology used to send multiple signals over a single optical fiber. There are two primary types of WDM: Coarse Wave Division Multiplexing (CWDM) and Dense Wave Division Multiplexing (DWDM). CWDM uses larger range of wavelengths, typically separated by 20 nanometers. This leads to a simpler sy
