Optical Communications Laboratory

Lab activities

Lab activities consist of measurements/experiments in the following optical communications sectors:
EDFA amplified transmission over up to 500km of straight-line dispersion-managed fiber of WDM signals with 10Gb/s OOK-NRZ modulation
"Recirculating loop" configuration to propagate the WDM signal over multiple distances of available fiber stretch
Characerization of direct-detection receivers with noise loading for bit-error-rate measurements. Use of advanced software to extrapolate BER and Q-factor from received high-quality data (Bergano's method).
Analysis of power transients in EDFAs, and semiconductor optical amplifiers (SOA) without and with gain-clamping (GC) (standard GC-Alcatel SOAs and Finisar vertical-cavity linear optical amplifiers (LOA)).
SOA and GC-SOA measurements in collaboration with Turin Politechnic PhotonLab within the Italian-ministry funded projects OSATE and WONDER, and with research group of Prof. L. A. Rusch at Laval University, Qu├ębec, Canada.
Measurements of propagation of Gb-Ethernet signals over multi-mode fibers. theoretical study and simulations of 10GbE MMF propagation.


The following main measurement equipment is available:
Miscellaneous optical and electro-optical components:
All instruments are connected to PCs through IEEE-488 (GPIB) interfaces.
Many components and instruments are generous donations by: Cisco, Alcatel-Lucent and Marconi.

Software applications and Virtual Instrumentation

Software for data measurement automation was developed in LabVIEW 8.0.
All lab PCs are: Powered by Gentoo Linux
