CATV Direct Modulated 1550nm Optical Transmitter With SNMP For FTTH
CATV Direct Modulated 1550nm Optical Transmitter With SNMP For FTTH Application
Main features:
* Adopt international famous brand laser with low-noise, narrow linewidth and continues wave as the optical source, adopt high linearity LiNbO3 external modulated as the signal modulation.
*Good SBS suppression design cam supply longer transmission distance. SBS threshold value can be adjusted makes more flexible configuration. Meanwhile it can suppress SBS-Stimulated. Brillouin Scattering and optical fiber SPM-self phase Modulation phenomenon, it improves the optical power of optical transmission also maintain the linearity.
* SBS threshold value adjustable types are 13, 16 and 18dBm, it can be adjusted as per users’ actual situation.
* RJ45 network management interface, 19" 1U standard framework.
