Black GFS1550F-E CATV Optical Transmitter / 1550nm Optical Transmitter
● Both the external modulator and laser are imported from the United States orJapan.
● Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
● Perfect SBS suppress circuit and adjustable SBS in 13,16, 18,suitablefor different types of CATV net.
● AGC control.
● Internal double power which can be changed automatically.
● Automatically shell temperature control.
● Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
● The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
● High performance: Externally modulated technology, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~1000MHz.
● 1+1 powers supply back, up hot-plug function available.
● Narrow bandwidth (0.65MHz), lower noise, DFB continuous wave laser, is propitious to reduce the influence of the dispersion.
● The operating bandwidth is up to 47~1080MHz.
● ITU standard wavelength, ± 200GHz (± 1.6nm) adjustable.
● AGC/MGC mode is optional at spot. OMI can be optimized at spot.
● Perfect RS232 communication interface.
● Advanced SNMP network management function.
● Casing temperature auto-control.
● Excellent P/P ratio.
