Pico Macom L860 User manual

L860
Broadband 54-1000 MHz forward bandwidth,
5-36 MHz active reverse path
30 dB typical forward-path gain for optimum
performance to overcome combining losses
and provide ample level for distribution
20 dB active reverse-path gain for extra level
to distribute reverse path signals to CMTS and
other upstream applications
Adjustable gain and slope controls to
optimize carrier-to-noise ratio and provide
superior picture quality and easy
system balancing
Plug-in equalizers and attenuators
(included) enable uniform gain and slope
system balancing for minimum distortion
Employs dual state-of-the-art push-pull
hybrid technology for very low distortion,
high input and output capability
-20 dB input and output test points
enable simplified setup and performance
monitoring without service interruption
Built-in lightning and line-voltage surge
protection safeguards the unit from damage The MACOM L860 two-way broadband distribution amplifier is a high quality dual push-pull amplifier producing forward
and reverse signals with extremely low distortion and high output levels. The amplifier is capable of operation over the
54-1000 MHz range in the forward path and provides a 5-36 MHz return path. This amplifier is designed for bi-directional cable
distribution systems used in institutional and MDU environments, which employ reverse path signals such as cable modems,
remote status monitoring and remote TV origination. This rack-mounted amplifier makes an excellent headend launch amplifier
and can be used in conjunction with the MACOM C860 passive headend combiner to overcome losses associated with signal
combining in broadband CATV systems. The MACOM line is backed by an industry leading 5-year limited warranty.
