Máy Phát Quang 1550nm FWT-1550EH
FWT-1550EH series externally modulated optic transmitter, which accords with current international industry technique standard is a 1550nm Externally Modulated Optical Transmitter.
The whole unit light source adopts narrow line width(Typ.=0.65MHz), low noise and continuous wave DFB laser, which is propitious to reduce the influence of dispersion.
The whole unit signal modulation adopts CATV special LiNbO3 external modulator of American company and FULLWELL optimized control technology with independent intellectual property, so FWT-1550EH series externally modulated optic transmitter can reach high index of back to back, CNR≥52dB, CTB≤-65dB, CSO≤-65dB, 47~862MHz, SBS:13~19dBm adjustable.
The whole unit is equipped with perfect RS232 communication interface, SNMP network management, 1+1 back-up power supply, hot-plug function available and casing temperature auto-control.
FEATURES:
◆ High performance:externally modulated technology, no laser chirp, low dispersion, high extinction ratio, with excellent characteristic within 47~862MHz.
◆ 1+1 back-up power supply, up hot-plug function available.
◆ Narrow bandwidth(Typ.=0.65MHz), low noise and DFB continuous wave laser, propitious to reduce the influence of dispersion.
◆ CNR≥52dB and excellent CTB, CSO index.
◆ SBS:13~19dBm adjustable.
◆ ITU standard wavelength, ±200GHz(±1.6nm)adjustable.
◆ AGC/MGC mode is optional at spot, OMI can be optimized at spot.
◆ Advanced SNMP network management function.
