What is this white paper about?
Building dark fiber network infrastructure using WDM technology used to be considered a complex challenge that only carriers have the means to implement. Due to this complexity, many enterprises implemented passive solutions, limiting future growth and binding them to an inferior technical solution for essential network infrastructure.
There are two main methods for building DWDM networks:
- Active solution, where DWDM infrastructure is built using transponders and muxponders agnostic to the routers and switches in the network, and provide the full optical demarcation point, and full performance monitoring and diagnostic tools for all optical ports.
- Passive solution, which includes passive filters and ADMs (add/drop multiplexer), and colored optics plugged into equipment such as routers and switches.
