Build a 1Gbps link as long as possible without regeneration. Assume a transmitter power of 1mW and a receiver sensitivity of -30dBm for a BER of 10^(-9). The dispersion at 1.5 micron is 20 ps/km.nm, and the attenuation is 0.25 dB/km. What would be the maximum length if you choose (1) a wavelength of 1.5 micron and single-mode, GRIN, or step-index multimode fiber or (2) you choose a wavelength of 1.3 micron? Assume that the bandwidth of the transmitted signal is about 1 GHz.

Discuss the following assertions:
(a) Dispersion limits the (bit rate) x (length) product
(b) Attenuation limits the length
(c) Dispersion limits the bit rate
(d) If the fiber is single mode, it still has dispersion
(e)WDM increases the bit rate by reducing dispersion.
