ECE 731 - Spring 2006 - Problem Set #6 Due: Wednesday, May 31, 2006 1. Photodiodes. Chapter 13, Problem 4 in Pollack. 2. Point-to-point links: Power Budget. Consider 0.85 µ m lightwave digital link with a transmitter power of dBm P tr 0 = , a receiver sensitivity of dBm P rec 42 = , a fiber loss of km B / 5 . 3 d f = α , a connector loss of dB con 6 . 0 = , a splice loss of dB splice 2 . 0 = , and a system margin of dB M s 6 = . What is the maximum reliable length for the link? 3. Point-to-point links: Rise Time Budget.

Unformatted text preview: Consider a 50 km 1.3 m digital link designed to operate at 1 Gbit/sec over a single-mode fiber. The transmitter rise time is T tr = 0.25 ns and the receiver rise time is T rx = 0.35 ns. The source spectral width is = 3 nm. Material and waveguide dispersion are characterized by a dispersion parameter D of 2 ps per nm km at the operating wavelength. Can the system operate in the RZ format?...
