2809 79 Channel LDS CATV Optical Receiver DATASHEET | JULY 2014 FIBER OPTICS The 2809 79 Channel CATV Optical Receiver facilitates a low-cost system for transporting up to 79 channels of VSB/AM modulated signals over a singlemode optical fiber. The 2809, working with 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 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. RF & Optical Characteristics Applications CATV Parameter Video Distribution Systems Features Bandwidth of 40 to 550 MHz Accommodates Up to 79 Channels Provides Excellent Picture Quality with a CNR up to 54.5 dB, CSO of -63 dBc, and CTB of -66 dBc Low Profile, Rugged Package Allows Great System Installation Flexibility Min Typ Max Units Optical Input Power -8.0 0.0 +4.5 dBm Operating Wavelength 1280 1310 1340 nm Operating Wavelength 1490 1550 1610 nm 40 - 550 MHz - 75 - Ohms RF Output Level - +18 - dBmV RF Output Return Loss - 16 - dB Back Reflection Tolerance - - -50 dB Required Fiber Bandwidth Bandwidth Output RF Impedance 2,000 - - MHz Composite Second Order (CSO) - -63 - dBc Composite Triple Beat (CTB) - -66 - dBc Wide Optical Input Range of -8 dBm to +4.5 dBm Permits the Use of a Lower Power Transmitter, Reducing System Cost System performance specifications indicated for use with 9/125 µm singlemode fiber.
