Wavelength Converter

What is Wavelength Converter?

• A Wavelength converter is a device that convert data from one incoming wavelength to another wavelength
• Their most important use will be for avoidance of wavelength blocking in optical cross connects in wavelength division multiplexed (WDM) networks
• Thereby the converters increase the flexibility and the capacity of the network for a fixed set of wavelengths.
• Wavelength converters are useful components in WDM networks for three major reasons.1.Data may enter the network at a wavelength that is not suitable for use within the network.

  2.Wavelength converters may be needed within the network to improve the utilization of the available wavelength on the network link.

  3.Wavelength converters may be needed at boundaries between different networks if the different networks are managed by different entities and these entities do not coordinate the allocation of wavelength in their networks.
