Investigating Pluggable Transceivers' Laser Linewidth, Chirp, and Stimulated Brillouin Scattering Effects on Data Transmission in Different Kinds of Optical Fibers

摘要

Pluggable transceivers; either small form factor (SFP) that operates up to 2.5Gbps or XFPs that operates at 9.95Gbps, transmitter's laser characteristics are investigated experimentally. The laser linewidth and chirp in addition to stimulated Brillouin scattering (SBS) threshold for different transceivers are measured over many kinds of optical fiber. The measured transceiver's parameters are correlated and used to explain different system performance penalties encountered during data transmission over different kinds of optical fiber. This knowledge is valuable to system engineers as it is not available and not provided by transceivers' vendors. System performance penalties for different kind of fibers with positive and negative accumulative dispersion are measured experimentally at OC-192 and OC-48 modulated signals for different XFPs and SFPs, respectively.
