Alcatel-Lucent and Vodafone have been engaged in co-development of TWDM-PON since 2010 to test potential deployment scenarios for the technology. During this time the companies have contributed to its standardization and completed a successful trial.
TWDM-PON technology has been selected as the successor to current GPON (Gigabit Passive Optical Networks) technologies. TWDM-PON uses four wavelengths per fiber, giving a total capacity of 40 gigabits-per-second (Gbps), and can support new operational and business uses that create a much faster and higher return on investment for operators than previous generations of PON technology.
TWDM-PON enables an operator to deliver different services over each wavelength. For example residential, business and mobile backhaul services can be carried over a single fiber. This reduces costs and increases revenue opportunities as more services can be provided with the same infrastructure.
Each fiber can be flexibly configured to enable customer services ranging from a few megabits-per-second up to 10 gigabits-per-second.
