IP-over-DWDM - how does it work?

iPodWDM is the idea of implementing DWDM connections without the use of transponders and “gray” modules, which until now were necessary to connect switches or routers to transmission systems.

IP-over-DWDM - why is it worth it?

The experience of network operators indicates that the implementation of IP-over-DWDM can reduce investment costs in backbone networks by up to 65% compared to traditional systems based on transponders and muxponders.

In addition, the use of this technology allows space savings in data centers of up to 80%, as well as a significant reduction in energy consumption, which can range from 70% at the edge of the network to 90% at its core. This is an excellent solution for building efficient and sustainable networks.

• Higher bandwidth

iPodWDM allows you to significantly increase network bandwidth without the need to add additional fiber cables.

• Cost reduction

iPodWDM reduces both capital (CAPEX) and operational (OPEX) costs by eliminating the need for additional equipment such as transponders.

• Lower power consumption

iPodWDM systems use less energy compared to traditional solutions, which translates into lower energy bills and a lower carbon footprint.

• More space

Reducing the number of devices needed saves space in data centers, which is crucial in the context of limited space.

• Easier network management

iPodWDM simplifies the network architecture, making it easier to manage and maintain.

• Scalability

iPodWDM systems offer better scalability, allowing you to easily adapt to growing network needs.

What modules work in IP-over-DWDM systems?

Thanks to the actual standardization GBC Photonics DWDM 400G OpenZr+ 0dBm coherent modules can be installed directly into the QSFP-DD ports of routers and switches of any manufacturer, which greatly simplifies the DWDM system structure.

The compatibility of these modules is ensured by the GBC Photonics SRD (Smart Recode Device) environment, in which the user can independently, using a computer or smartphone, program his module to work with the equipment that works in his network.
