Cisco Cable TV Optical Node and RF Amplifier Teardown

Teardown of Cisco / Atlanta Scientific Cable TV optical node and drop amplifier. These are modern versions running on fiber networks. These small amplifiers are used in houses where it is not practical to use a receiving antenna to get the signal from the broadcast headend transmitter. They are also called a "service drop". Historically CATV is short for Community Antenna TV. A large receiving antenna was used and a cable connection ran out to every house in the neighborhood. Each house had one of these amplifiers. The return path amplifier can also send some of the signal back into the line to keep the signal good enough for the next house. In Denmark, the large receiving antennas has mostly been substituted with fiber connections.
