The LE1000 line amplifier thanks to it's modular style and to the 3 different gain value can be adapted to each
CATV network. The automatic controlled return path ingress switch, the dividable high level output, the module
defined breakpoint frequency up to 1 GHz and the optional automatic gain and slope control unit as well as the
exchangeable tray make the device the best choice for HFC solutions.
• Downstream frequency range up to 1006 MHz
• Upstream frequency range up to 204 MHz
• Optional connection to Monitoring System
• GaN output stage
• Automatic gain and slope control
• Automatic ingress management by the RSW module
