What is Wavelength Blocker | Basics of Wavelength Blocker
This page explains basics of Wavelength Blocker used in fiber optical domain. It mentions function of Wavelength Blocker ROADM type.
Following are the features of Wavelength Blocker type of ROADM:
• It functions as dynamic channel equalizer.
Here max. attenuation provides complete cutoff functionality i.e.
it acts as ON/OFF switch.
• It utilizes 'broadcast and select' architecture.
• It is used in long haul networks.
• It has 80 channels with spacing of about 50GHz.
• The ports are colored.
• It is expensive with the limited functionalities offered.
• It is used in older systems.
