Unleashing the full capacity of the installed fibre base
Unleashing the full capacity of the installed fibre base
There are some 20 million kilometres of installed fibre transmission links throughout the world, the great majority of which operate at a wavelength of 1.3µm. These links are limited in capacity by a combination of fibre loss and the bandwidth of their electronic repeaters, both of which limitations can be removed by the use of optical amplifiers. It is therefore highly attractive to consider uprating the world's installed fibre base by the simple installation of optical amplifiers. In the absence at present of a suitable commercially-available 1.3µm amplifier, it has been proposed to change the operating wavelength from 1.3µm to 1.55µm of those fibre links which have been specified for dual-window operation, thus enabling the erbium-doped fibre amplifier (EDFA) to be employed. The penalty of this approach is that the chromatic dispersion of the fibres is high (17ps/nm.km) at 1.55µm and must be compensated if a reasonable transmission capacity is to be achieved. Thus upgrading existing installed 1.3µm links involves either developing a viable 1.3µm amplifier or operating at 1.55µm using EDFAs and dispersion compensation.

Abstract
There are some 20 million kilometres of installed fibre transmission links throughout the world, the great majority of which operate at a wavelength of 1.3µm. These links are limited in capacity by a combination of fibre loss and the bandwidth of their electronic repeaters, both of which limitations can be removed by the use of optical amplifiers. It is therefore highly attractive to consider uprating the world's installed fibre base by the simple installation of optical amplifiers. In the absence at present of a suitable commercially-available 1.3µm amplifier, it has been proposed to change the operating wavelength from 1.3µm to 1.55µm of those fibre links which have been specified for dual-window operation, thus enabling the erbium-doped fibre amplifier (EDFA) to be employed. The penalty of this approach is that the chromatic dispersion of the fibres is high (17ps/nm.km) at 1.55µm and must be compensated if a reasonable transmission capacity is to be achieved. Thus upgrading existing installed 1.3µm links involves either developing a viable 1.3µm amplifier or operating at 1.55µm using EDFAs and dispersion compensation.
