Soviet laser telephoning shows early operational tests in Armenia
A Soviet scientist reported 15 mile 24 channel laser telephoning between Yerevan and Barakan Observatory as the world's first operational laser telecom link. Other tests include a 6 mile 240 channel system in Moscow. Lab work by Kazaryan noted 80 percent reliability during peak times. plans to use carbon dioxide lasers and underground beam channels to combat weather and interference.
