The 2808 110 Channel VSB/AM Optical Receiver provides CATV distribution headend
operators with an extensive array of features that offer a low-cost solution to increase
system performance. The receiver provides an RF output of +28 dBmV allowing multiple
RF splits without the use of an external RF amplifier. The 2808 is equipped with a manual
gain control that allows the user to adjust the RF output level for optimum performance.
Additionally, the receiver’s ability to operate over a wide optical input range of -8 to +4.5
dBm allows for a variety of system designs without degrading performance. The 2808 can
transport up to 110 CATV channels using the entire high-frequency bandwidth, or
alternatively, it can transport up to 80 channels of standard analog CATV signals while
utilizing the remaining high-frequency bandwidth to transport 30 digital QAM channels. The
receiver includes a universal AC power supply, freeing the user from a bulky wall-mount AC
adapter. The streamline design of the 2808 offers the flexibility and performance demanded
by today’s broadband professional.
