Dense Wavelength Division Multiplexing technology is the cornerstone for any network infrastructure. Initial deployments of DWDM systems were in national and international networks. The technology presents large increase in bandwidth without installing additional dark fiber. Those same drivers are relevant today in regional, metro networks and campus environments.

The key features and benefits of DWDM are:

  • Transparency – DWDM is a physical layer architecture. It can be protocol agnostic and supports TDM and other Data formats. (ATM, Gigabit Ethernet, Fiber channel and SONET)
  • Scalability – Leverage dark fiber to expand up to 128 channels over single pair of fiber.
  • Network Resiliency – Create path or channel resiliency with east and west facing networks.
  • Segmentation – Architect your network based on application and function.
  • Dynamic provisioning – Simply, quickly and dynamically provision network connections in minutes.


Reconfigurable Optical Add/Drop Multiplexers (ROADMs) technology allows operators to dynamically and remotely configure channels on an as needed basis. Prior to ROADMs, operators designed DWDM systems using fixed filters. Although fixed filters are still widely deployed in applications that are static, ROADMs are the desired technology for larger more rapidly and dynamic networks.

The key benefits of using ROADMs are:

  • CLI based wavelength selection. No longer need to physically connect optics. Drop any channels at any site quickly and easily.
  • Automatic power monitoring and balancing. Eliminate the need for manual tuning.
  • Auto-power balancing
