1550nm CATV Optical Transmitter Direct Modulation Wt-1550-Dm

WT-1550-DM intelligent directly modulated optical transmitter is mainly used in 1550nm optical fiber transmission system. Adopt advanced electronic dispersion compensation technology, accurately compensate according to the actual transmission distance by 1km stepping. The maximum compensated distance up to 50km.

Model Selection:
WT-1550-DM-I: standard 1550nm directly modulated optical transmitter, the default optical output power is 10mW, and the optical output wavelength can choose ITU standard wavelength.
WT-1550-DM-II: on the base of WT-1550-DM-I, add inter-cut function and built-in WDM. The WDM specification please specify when ordering.
WT-1550-DM-III: on the base of WT-1550-DM-I, add VOA Variable Optical Attenuator.
WT-1550-DM-IV: on the base of WT-1550-DM-II, add VOA Variable Optical Attenuator, can adjust the signal optical power intensity by the menu options on the front panel.
