Fiber Conservation (CWDM)

Broadband has unveiled a new world for subscribers, full of advanced capabilities and faster speeds. Your challenge is to meet their demands without compromising your budget. Because of its distance, speed and bandwidth potential, fiber optics has become the choice for many service providers. Fiber optic connections typically require two strands of fiber – one for transmitting and one for receiving signals. But, what happens when you need to add services or customers, but you’ve exhausted your fiber lines?

Coarse Wave Division Multiplexing (CWDM) technology is the most effective solution for expanding bandwidth and has many advantages over DWDM technology in terms of system costs, set-up, maintenance, and scalability. CWDM is a technology which multiplexes multiple optical signals on a single fiber optic strand by using different wavelengths, or colors, of laser light to carry the different signals. By utilizing bidirectional communications over a single strand of fiber, network managers can realize a multiplication effect in the capacity of their available fiber infrastructure.

Cost-effective optimization of fiber

Bury the idea for additional fiber lines. That’s a long, expensive and unnecessary risk. Transition Networks offers a wide range of CWDM products. These low-cost, passive options leverage your existing network and provide new and additional revenue generating services to customers. Seamlessly integrate CWDM multiplexers to incrementally increase your optical solution to up to 16 different wavelengths all transmitting different standards, data rates or protocols over one single fiber optic link with up to 10GB throughput on each port over your existing fiber links.

Transition Networks CWDM products come with our industry-standard lifetime warranty so you can be assured your subscribers will receive the highest levels of service quality and reliability. Understanding WDM Technology

Benefits of CWDM

  • Passive equipment that uses no electrical power
  • Much lower cost per channel than DWDM
  • Scalability to grow the fiber capacity as needed
  • with little or no increased cost
  • Protocol transparent
  • CWDM can provide connectivity for multiple Wireless Carriers using virtually any protocol to the cell tower over a single strand of fiber.
