Again, the definitions of the three options for optical architectures are:
- Colorless - any color wavelength on a single fiber can connect to any add/drop transponder associated with that fiber.
- Partial Colorless/Directionless - a compromise architecture with some level of blocking such that not all waves on all fibers can connect to all transponders.
- Colorless/Directionless/Non-Blocking - extends the concept to any color wavelength on any fiber from any direction - all can be connected to any add/drop transponder.
However, this architecture is only realizable using an optical switch component (like those from Polatis) that includes key capabilities - such as low loss and low power consumption - that allow it to integrate easily and without impact to the existing infrastructure. In our next blog, we'll detail how Polatis can help make Colorless/Directionless/Non-Blocking architures a reality - today.
