Alcatel-Lucent 1626 Light Manager
R E L E A S E 6 . 1
The Alcatel-Lucent 1626 Light Manager (LM) is a global 10G/40G multi-reach Dense Wavelength Division
Multiplexing (DWDM) platform for regional, long-haul terrestrial and unrepeatered submarine applications. As
new multimedia services fuel huge bandwidth growth and time-to-service becomes key to business success,
capacity, flexibility and ease of operations are driving the requirements for next-generation regional and backbone
photonic networks. The combination of networking flexibility, operational efficiency, traffic scalability and optical
performance makes the Alcatel-Lucent 1626 LM the ideal platform to support profitable transport network growth.
