Optical WDM Market Outlook and Trends
Optical WDM Market Outlook and Trends
The wavelength division multiplexing (WDM) market is poised to experience strong growth driven by the exponential growth of Internet traffic and bandwidth demand. WDM technology transmits multiple optical signals using different wavelengths through a single fiber, effectively multiplying its bandwidth. The ability to maximize the capacity of existing fiber infrastructure makes WDM systems appealing to network operators facing ever-increasing bandwidth demands from Internet users, enterprises and data centers.
Market Drivers
The key drivers fueling growth of the WDM market are:
•Expansion of telecom networks to support surging data usage from 4G/5G, Internet of Things, and cloud services.
•Implementation of high capacity WDM systems for data center interconnects between and within large cloud service provider networks.
•Adoption of software-defined networking (SDN) and network function virtualization (NFV) which integrate seamlessly with WDM technology.
•Declining costs of WDM systems due to technology advancements and economies of scale enabling wider adoption.
•Proliferation of short reach and medium reach (under 10 km) WDM networks within data centers compared to long haul networks.
Market Trends
Major trends shaping the optical WDM market include:
•Transition from fixed grid to flexible grid WDM networks to improve spectral efficiency and support flexible bandwidth channels.
•Increasing channel counts with next generation systems scaling to 1 terabit per second and beyond through advancements in modulation formats and multiplexing techniques.
•Use of super-channels that aggregate multiple subcarriers into wider channels of up to 1 terabit per second for higher capacity and spectral efficiency.
•Integration of WDM with software-defined networking for programmability, automation and on-demand provisioning
•Combination of optical and electrical technologies into integrated opto-electrical networks to facilitate deployment in metro and data center networks.
•Proliferation of multimode WDM systems for data center interconnects and short reach applications due to higher port density requirements.
•Transition to a systems integration model where network operators specify requirements and outsource implementation to solution providers. This requires broadening the skill sets of traditional network engineers.
Future Outlook
The future prospects for the WDM and optical fiber cable markets are positive. The fundamental drivers of bandwidth growth show no signs of slowing as data usage and Internet traffic continue to explode. Network operators will continue to leverage WDM technology to maximize the capacity of their existing fiber infrastructure to keep up with demand. Technological advancements will enable WDM systems to scale capacities to terabit level while decreasing costs. With numerous trends converging, the optical WDM market is poised for strong growth over the next 5-10 years.
