This amplifier takes place between the optical node and the first amplifier on the line. It is built in the system in
case of forward path bandwidth upgrade and it's function is to improve the gain and establish high enough signal
level also in the extended, higher frequency range by this. The return path frequency range is not hindered by
additional filters, so it is easy to realize a return path bandwidth upgrade up to 204 MHz. The device has very low
power consumption and allows to set the exact output level and an additional tilt.

• 1006 MHz forward path bandwidth
• Even 204 MHz reverse path bandwidth
• For cost-effective network upgrade
