Model 2809 Limited Distance Solution
(LDS) CATV Receiver,
working with the Model 2806 LDS transmitter, provides
a low-cost system for transporting 77 channels of VSB/AM modulated signals over
a single-mode optical fiber. The LDS link provides excellent performance up to 10
km with full channel loading, high sensitivity, and 40-550 MHz of usable band-
width. With a wide optical input range of -8.0 dBm to +4.5 dBm and an RF output
of +18 dBmV at 0 dBm optical input, the Model 2809 allows high quality signal
transport for intra-facility limited distance applications, such as corporate CATV
delivery and FTTC where cost, small size, and performance are major consider-
ations. This low-cost system allows CATV providers with the ability to provide a
reliable limited distance fiber optic video distribution system.
