The QAMnet DDM Dense-Wavelength Drop Modules allow system designers optimal flexibility to configure multiple DWDM wavelength HFC networks.
Product Overview
The QAMnet DDM Dense-Wavelength Drop Modules allows optimal flexibility to system designers for configuring multiple DWDM wavelength HFC networks. A specific DWDM wavelength can be removed (Drop) from the incoming optical signal. These easy-to-use devices can be used to in a series, so wavelength Drop can be done incrementally. The DDM devices offer low insertion loss and high isolation in a totally passive device. It can be ordered in unpackaged device form or a connectorized module, housed inside a precision machined aluminum package.
