PriTel manufactures EDFAs with excellent sub-picosecond pulse performance—with very low dispersion and low PMD without the use of dispersion-compensating fiber that causes high nonlinearities. As seen in the accompanying diagrams, these amplifiers do not significantly change the input pulsewidth. Certified shortpulse performance to 300 fs or to 600 fs is available in models from 13 dBm to 22 dBm saturated output. Contact PriTel for information about certified performance to 700 fs for models from 23 dBm to 30 dBm saturated output.
