Meeting bandwidth capacity needs of customers is a crucial business objective for today’s providers. While both coarse wavelength-division multiplexing (CWDM) and dense wavelength-division multiplexing (DWDM) are modern forms of wavelength-division multiplexing (WDM) that effectively solve those increasing bandwidth needs by upgrading the utilization of new and existing fiber, they are each designed to tackle different network challenges.

As hybrid and remote work continues to become the norm for businesses of all sizes, organizations are increasingly gravitating to cloud-based unified communication tools to boost internal collaboration and stay connected to customers. Microsoft Teams is already one of the most popular choices for chat and meetings and it is becoming a popular tool to use as a cloud-based business phone system.

Today’s telecom, cable, and data providers constantly compete to provide the best, most reliable service to customers, while investing in the right technologies to maintain the integrity of data and enable the separation of users. Because of this, service providers often spend countless hours searching for cost-effective, yet future-proof solutions that fit their business needs. This is where DWDM comes in.

Receiving a phone call from an unfamiliar number—and deciding whether or not to answer that call—has become an increasingly pervasive problem for nearly everyone. Sophisticated robocalls and Caller ID spoofing are now a regular (albeit frustrating) part of consumers’ daily lives.

Remote and hybrid work have made Microsoft Teams a core tool in nearly all large organizations. Many business leaders and IT administrators would like to extend the value of Teams to enable users to make and receive business phone calls. This improves the productivity of their employees by keeping them connected with customers, business partners, and co-workers in the office, at home, or even on the road.
