The QAMnet DADM Dual Add-Drop Module allows optimal flexibility to system designers for designing multiple wavelength HFC networks system for DWDM wavelengths add/Drop.
Product Overview
The QAMnet DADM Dual Add-Drop Module allows optimal flexibility to system designers for designing multiple wavelength HFC networks system for DWDM wavelengths add/Drop. DADM is a four port device. It removes an optical signal with a specific wavelength from the optical fiber input through a Drop port. At the same time, a signal with this specific wavelength can be inserted through the Add port to the fiber output port. These easy-to-use devices can be used to in series, so wavelength add/drop can be done incrementally, allowing flexibility in system design. These DWDM based devices offer low insertion loss and high isolation. It is a passive device that is housed inside a compact aluminum package.
