The specifications for the system are summarized in the table below Transmission rate Output power Operating wavelength Spectral width Zero-dispersion slope0.09 Zero-dispersion 2.5 0- 6.2 1550 0.6 Gb/s dBm nm nm Transmitter psm'-km 1312 nm Fiber wavelengtlh dB Input/output coupling 0 efficiency The fiber attenuation factor and coupling efficiencies are set to 0 in order to isolate the effects of dispersion from those of attenuation. Using the data in the table (and in the fiber data sheet) and the theory summarized above, determine the dispersion-limited fiber length
