Optical communication involves using light waves as the medium for transmitting data. To enhance the bandwidth of an optical fiber, two main approaches are commonly used: increasing the data rate per channel or multiplying the number of wavelengths transmitted through a single fiber, known as wavelength division multiplexing (WDM). Despite these advancements, optical communication systems are typically limited to shorter distances, usually within a few kilometers, due to signal degradation and other technical constraints. Although the technology behind optical communication is well-established, the demand for such services hasn't always matched expectations. Take FTTH, often referred to as the "final mile" of broadband access, as an example. The underlying technology, such as EPON, is fully developed. However, most residential users don’t require extremely high bandwidth for basic internet usage, which has limited the widespread commercial adoption of FTTH. That changed in 2006 when triple-play services like IPTV became more popular. As users began demanding higher-quality video streaming, the existing network infrastructure struggled to keep up, prompting operators to accelerate FTTH deployment. At the same time, technologies like ASON (Automated Switched Optical Network) gained attention for their ability to dynamically manage network resources and offer tailored solutions for enterprise customers. Since many telecom providers rely heavily on business clients, they have been willing to invest significant resources into building ASON networks to meet the growing needs of companies that require flexible and reliable connectivity. This shift has further driven the development and integration of advanced optical communication systems in both residential and enterprise markets.
