The Bell System uses many types of transmission media to carry telephone calls, computer data, and television signals.
This paper describes the design, packaging, and performance characteristics of the optical detector packages used in the receiver portion of the regenerator employed in the Atlanta Fiber System Exp

Solid-state photodetectors are particularly well suited to optical communications.
An optical regenerator* is essentially a digital regenerator with optoelectronic transducers at the input and output.
In 1974, the acquisition of a fiber-optics development laboratory was started by the Western Electric Product Engineering Control Center in Atlanta.
A variety of multimode, low-loss glass fibers consisting of a core of germania borosilicate glasses and a cladding of fused quartz have been prepared over the past several years using the modified
Tests of an experimental lightwave transmission system operating at 44.736 Mb/s (DS3), the third level of the Bell System digital hierarchy, were begun by Bell Laboratories in January, 1976.
The Atlanta Fiber System Experiment1-2 utilizes cable ducts similar to those currently being installed in the telephone plant, but atypical of active Bell System ducts in that they were dry and unc
Exploration and mapping is a fundamental capability of a swarm of robots: robots enter an unknown area, explore it, and collectively build a map of it.
