[. . . ] [. . . ] Implementing Zero-Touch Photonics, they transform traditional WDM into a cost-effective, low-footprint and fully flexible transport layer with complete visibility and control of individual wavelengths. This transformation simplifies broadband service delivery, speeds time-to-revenue generation and facilitates bandwidth expansion in optical transport network (OTN)-based metro access networks. The Alcatel-Lucent 1830 PSS-1 is a compact, one rack unit (RU) customer premises equipment (CPE), hardened for outdoor deployment and available in different fixed configurations. The Alcatel-Lucent 1830 PSS-4 has a two RU chassis with four slots available for service cards, the same cards supported by the Alcatel-Lucent 1830 PSS-16 and the Alcatel-Lucent PSS-32 (see Figure 1).
