Abstract
A long haul optical fiber transmission system includes a transmitter having a modulated bit rate of at least 40 Gb/s. A receiver is optically coupled to the transmitter with a composite optical fiber span. The optical fiber includes a first optical fiber coupled to the transmitter and a second optical fiber coupled to the first optical fiber. The first optical fiber has an effective area of at least 120 μm, an attenuation of less than 0.180 dB/km, and a length Lfrom about 30 km to about 90 km. The second optical fiber has an effective area of less than 120 μm, an attenuation of less than 0.180 dB/km, and a length L. The sum of Land Lis at least 160 km. The composite optical fiber span does not include a repeater along the length of the span between the transmitter and the receiver or any rare earth dopants.
