Model 2808 110 Channel CATV Optical Receiver DATASHEET | JANUARY 2012 Features Wide Bandwidth of 40 to 860 MHz Accommodates up to 110 Channels on All Models. Provides Excellent Picture Quality with a CNR up to 54.5 dB, CSO of -63 dBc, and CTB of -66 dBc. RF Output up to +28 dBmV Allows a Greater Number of Drops or Splits. Wide Optical Input Range of -8 dBm to +4.5 dBm Permits the Use of a Lower Power Transmitter, Reducing System Cost. Built-in, Universal AC Power Supply Frees System User from Bulky WallMount AC Adapters. FIBER OPTICS The Model 2808 110 Channel VSB/AM Fiber Optic 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 Model 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 Model 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 Model 2808 offers the flexibility and performance demanded by today’s broadband professional. 77/110 Channel CATV Receiver Part Numbers Description Part Number Fiberoptic Receiver, 1310/1550 nm, SC/APC Optical Connector 2808R-SFSP Fiberoptic Receiver, 1310/1550 nm, FC/APC Optical Connector 2808R-SFAP | REV 2012.01 Information contained herein is deemed reliable and accurate as of the issue date.
