1. Product Overview
When the 1550nm is used as the downlink transmission wavelength, the expensive price of the 1550nm external modulated
optical transmitter using the Mach-Zehnder Modulator and the severe dispersion effect of the conventional 1550nm directly
modulated optical transmitter are the difficulties in network upgrade.
So
we have developed a 1550nm optical transmitter
adopting the latest electroabsorption modulated laser (EML). It combines the advantages of the high performance, high SBS of
external modulated transmitter and high integration ,low cost of directly modulated transmitter. SBS can be up to 20dB in distance
transmission in 35KM, MER>40. Supports up to 1.2GHZ frequency band, two-way RF input, high isolation, can support QAM,
IPQAM broadcast, insert functions. Can be built-in CWDM, multi-wavelength networking.
