What is Metro WDM?

Long Haul► > 1000km

► DWDM, 10/40Gbps

► Optimized for maximum performance

Metro (Core & Regional)► Up to 250 - 1000 km► C and DWDM,

2.5/4/10/40Gbps► Optimized for price vs

performance► Easy of use and low power

consumption

WDM Access► Up to 40 km► CWDM sufficient

Metro WDM provides:–Simple high capacity pipes

► CWDM sufficient, 1/2.5/4/10Gbps

► Environmentally hardened

–Service separation and expansion by λ–Easy design and management in an investment.

Metro WDM is not only for Telco with high capacity y g p ytransmission but also for alternative operators.
