Fiber Optic Codec Link (FOCOL). Volume 1.

Abstract

The fiber optic codec link was designed to meet the majority of data transmission requirements for both Underground Nuclear Weapon Effects Tests and High Explosive Tests at a substantial cost saving over current transmission methods including other multiplexing systems. The link is capable of transmitting a maximum of 92 channels of data over a fiber optic cable up to two kilometers in length. The bandwidth of the input data is switch selectable as 5kHz, 10kHz, or 20kHz. Fewer channels are available at higher bandwidths as lower bandwidth channels are paralleled to achieve higher bandwidth channels. Greater dynamic range is provided by the use of companding analog to digital converters which feature higher resolution for small signals.
