Abstract
Coherent optical fiber communications had a brief period of popularity in the early 1990s, mainly because the optical links of that day were significantly power limited. Coherent detection provided a possibility of optically amplifying the signal to a power level that, after photodetection, made the thermal noise negligible. Two things, however, caused those coherent systems to be abandoned. The first was the sheer technical difficulties: a coherent receiver requires a local oscillator laser that is to be phase- and polarization-locked to the received signal. This gave rise to significant technical obstacles, and only a few limited and expensive coherent receiver solutions were demonstrated [17, 27]. The second was the development of the Erbium-doper fiber amplifier (EDFA) that provided an elegant and practical solution to the problem of the thermal noise. By 1995, the EDFA was a commodity in fiber communication systems, simple on-off keying modulation worked well enough, and coherent communication was forgotten.

Mathematically, a “ball” is defined as the set of points in Euclidean space whose distance to a given point is upperbounded by a given constant, i.e., the region bounded by a sphere. “Although physicists often use the term ‘sphere’ to mean the solid ball, mathematicians definitely do not” states Weisstein [55].
