The connected society now taking shape depends on robust and future-proof networking solutions for a range of fiber optic network applications – from corporate and governmental data centers to service provider networks. DWDM is increasingly a key ingred...

Both enterprise data centers and metro networks face increasing data traffic as the connected society takes hold, which puts pressure on network performance. This has driven the development of 400ZR for enabling 400G speeds with flexible hardware config...

The most common approaches for transporting data over a fiber network is by using single channel connectivity, embedded XWDM solutions or active, transponder-based WDM platforms. Each alternative is based on an organization’s access to dark fiber, eithe...

Enterprise data centers and service providers face increasing demands for data security, low latencies, higher speeds and longer distances in their networks. Transponders and muxponders are both key components for upgrading and enhancing their network i...

As enterprise and service provider networks have grown in size and scale, they have also become more complex and challenging to manage. One of the main drivers of this complexity has been the rise of disaggregated networks comprising components from dif...

As the world has grown more connected and data consumption has increased exponentially, methods of transmitting data have become all the more important. From a technological standpoint, fiber optics has served as a key enabler of these trends, setting a...

Wavelength division multiplexing, WDM, has long been the technology of choice for transporting large amounts of data between sites. It increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network....

We live in a world that is changing faster than ever, and that includes fiber optic network requirements. This means you will probably need to assign bandwidth and multiplex channels differently sooner or later. As a result, ROADM technologies have beco...

Driven by a general increase in data consumption in society and industry, higher bandwidth requirements have network operators looking to upgrade their metro networks. With new speeds and standards on the horizon, service providers and operators are cha...

Data center networking was initially focused on traffic within a single data center. However, over time connections between two or more data centers have become increasingly important. This is where data center interconnect (DCI) solutions come into pla...

The two key WDM technologies are Coarse Wavelength Division Multiplexing, CWDM and Dense Wavelength Division Multiplexing, DWDM. Which solution is best suited to a given environment depends on the network and user requirements.
