What’s your alternative to Nokia 1830 VWM (versatile WDM module)?
Some of our Mobile operator customers wonder if we have an alternative to the Nokia 1830 VWM (versatile WDM module). In this Knowledge Base article, we will find out.
As mobile networks expand globally and new base stations are deployed, it puts additional strain on the Mobile Fronthaul segment, where many operators are considering Centralized RAN. Using Passive CWDM or DWDM units in conjunction with colored 10G/25G optical transceivers is one of the most efficient ways to build a Centralized RAN transport network.
Nokia 1830 VWM (versatile WDM module) series is doing exactly that, utilizing passive Mux/Demux units that aid in increasing fiber capacity by providing up to 16 channels (CWDM) or 32 channels (DWDM) in a compact chassis.
As an alternative, we recommend considering our Passive 5G WDM Fronthaul portfolio, which covers a variety of Mobile Fronthaul topologies and provides potential building blocks: Passive CWDM/DWDM/LWDM in a diverse array for your mobile fronthaul transport network.

5G Fronthaul Passive WDM Mux/Demux Solutions
5G Fronthaul WDM technology will be important as global 5G networks scale and eventually new network topologies become popular such as 5G C-RAN (centralized RAN). 5G Mobile Networks necessitates massive investment in much denser radio networks and many new cells, which require the deployment of new optical CPRI fronthaul networks. Let’s take a step back and consider what makes 5G so unique? 5G mobile networks offer higher quality of service, lower latency, and greater bandwidth, which improves user experience and opens up a variety of new use cases. For 5G Fronthaul WDM – smart usage of colored eCPRI 25G optical transceivers and passive WDM technologies can achieve great savings and maximum efficiency of existing fibers. Mixture of colored transceivers and Passive WDM Technology is excellent choice, as it’s flexible, enables many network topologies, it’s protocol and bit rate agnostic and eliminates need for independent power supplies. Passive WDM can help not only in fronthaul and backhaul in 5G, but also has a great potential in industrial class networks used in such industries as Manufacturing, Oil & Gas, Mining, Power etc.
