<p>A novel technique of multiplexing called Tributary Mapping Multiplexing (TMM) is<br />applied to a single channel wavelength division multiplexing system and performance is monitored on the basis of simulation results. To elaborate the performance of TMM in this paper, a 4-User TMM system over single wavelength channel is demonstrated. TMM showed significant tolerance against narrow optical filtering as compared to that of conventional TDM at the rate of 40 Gbit/s. The above calculations are made by optical filter bandwidth and dispersion tolerance that was allowed at minimum. The spectral efficiency achieved by this TMM was 1 b/s/Hz and it was executed by using transmitters and receivers of 10 Gbit/s without polarized multiplexing. The high spectral efficiency, high dispersion tolerance and tolerance against strong optical filtering makes TMM an efficient technique for High<br />Speed Fiber Optic Communication.</p>

Fluorometric detection of analytes using batch injection analysis (BIA) has been investigated. BIA involves the injection of microliter samples toward a nearby detector which is immersed in a large-volume, nonflowing, blank solution. The characteristics and advantages of employing fiber-optic fluorometric detection for BIA are described. Similar to analogous flow injection measurements, batch injection fluorometric analysis offers high speed, reproducibility and simplicity, while eliminating the need for pumps, valves, and associated tubings. With injection rates at 120–500 samples/h, there is no observable carryover, and the precision is typically 2–3% (RSD).
