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.
