Suppose now the series of digital light pulses (101010…,) of light transmitted at a bit rate of 2.5 Gb/s is launched into a fiber from a laser diode with a 3 nm spectral width. Again, the fiber has a dispersion coefficient of 20 ps/nm-km. Approximately how far can these pulses travel before they are unrecognizable. Use the hint given in problem 2

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
