T. Widdowson et al., GLOBAL FIBER TRANSMISSION USING OPTICALLY AMPLIFIED REGENERATORS FOR MAXIMIZED REPEATER SPACING, Electronics Letters, 30(24), 1994, pp. 2056-2057
A global fibre transmission experiment consisting of optically amplifi
ed electronic regenerators has been demonstrated for the first time tr
ansmitting 5Gbit/s NRZ data with a extended span of > 200km to a dista
nce of 500000km.
