1830 Versatile WDM Module (VWM) Portfolio

Complete passive and active C/DWDM solutions to cost-effectively scale network capacity


With the growing demand to connect more devices and enable new applications, you need to cost-effectively scale network capacity. The Nokia 1830 Versatile WDM Module (VWM) portfolio supports next-generation WDM multiservice transport.

Provide passive or active extension of CWDM or DWDM to non-WDM-capable network elements. The Nokia 1830 VWM supports a wide range of applications and services, including mobile fronthaul.

Benefits and features

How can the Nokia 1830 VWM help you meet growing bandwidth demand and deliver new 5G services?

Deliver 5G services with better transport performance

The 1830 VWM product portfolio provides transparent transport with minimized latency and time error in support of new 5G services with stringent time/phase synchronization requirements.

Reduce operational costs

Quickly meet growing bandwidth demand while reducing OPEX. The 1830 VWM provides the energy saving characteristics of passive optical in a small footprint. And it enables simplified operations and pro-active monitoring.

Maximize revenue opportunities

The 1830 VWM portfolio supports a wide range of applications and services such as Carrier Ethernet, mobile backhaul and fronthaul. It enables you to support next-generation WDM multiservice transport in metro access, metro core, data center and enterprise networks.

Reduce CAPEX

The 1830 VWM product portfolio allows you to optimize your existing fiber installations, resulting in significant savings versus dark fiber.
