The module is used in the Motorola SG4000 node. Many older versions of this type are built with Fabry-Perot laser, and they are by all bandwidth limited. COMTECH is able to change the laser to a DFB one with higher power and even with CWDM wavelength, as well as to extend the bandwidth up to 200 MHz regarding to the DOCSIS 3.1 frequency plan. The upgrade task contains by default a fully comprehensive test procedure, which concerns not only the modified functions. After this a new label with modified type code and parameter list is sticked on the housing.
