Your flexible CATV solution provider COMTECH GYŐR HUNGARY LE1200 Line amplifier The LE1200 line amplifier thanks to it's modular style and to the 3 different gain values can be adapted to each CATV network. DOCSIS3.1 compliant forward path DOCSIS3.1 compliant return path Optional connection to Monitoring System GaN output stage Optional automatic slope and gain control Automatic ingress management by the RSW ingress module COMTECH Kft. © 1990-2016 H-9028 Győr, Török Ignác u. 66. The automatic controlled return path ingress switch, the dividable high level output, the module defined breakpoint frequency and the optional AGC unit as well as the exchangeable tray make the device the best choice for HFC solutions.
