Model 2809
77 Channel LDS CATV Optical Receiver
DATASHEET | JANUARY 2012
FIBER OPTICS
The Model 2809 77 Channel CATV Receiver facilitates a low-cost system for transporting
up to 77 channels of VSB/AM modulated signals over a singlemode optical fiber. The
Model 2809, working with Model 2806 transmitter, provides excellent performance up to 10
km with full channel loading, high sensitivity, and 550 MHz of usable bandwidth. With a
wide optical input range of -8.0 to +4.5 dBm and +18 dBmV of RF output at 0 dBm optical
input, the Model 2809 allows excellent performance for intra-facility limited distance
applications, such as corporate CATV delivery and campus/enterprise distribution where
cost, small size, and performance are major considerations. This low-cost system gives
CATV providers the ability to provide reliable limited distance fiber optic video distribution
systems.
Features
Bandwidth of 40 to 550 MHz
Accommodates up to 77 Channels.
Provides Excellent Picture Quality with a
CNR up to 54.5 dB, CSO of -63 dBc,
and CTB of -66 dBc.
