OPT-1550E-T is advanced type 1550nm external modulated optical transmitter with its high index and reliability. It's applicable for the over-long trunk of large and middle CATV station head-end, WDM system and CFG dispersion compensation system.
Under Back to Back tested in 59CH PAL/D and set SBS: 13~19dBm continuous adjustable test conditions this machine performance CNR ≥ 53.5dB, CTB ≤ -65dB, CSO ≤ -65dB.
The key components of this machine adopt DFB low noise, narrow linearity width and continuous wave laser. Adopting ITU standard wavelength, users can set and adjust the wavelength within the range of ±200GHz (±1.6nm) as ±0.05nm stepping. Its signal modulation adopts CATV special LiNbO3 external modulator combining with our advanced optimization technology. It can provide high quality images, digital or compressed digital signal when it use in over long distance transmission. This optic transmitter is applicable for the network upgrading and expansion of WDM system.
Features
(1) High performance: low dispersion distortion, No laser chirp, high extinction ratio, with excellent characteristic within 47~862MHz (47~1000MHz optional) in-band.
(2) High index: Excellent CNR, CTB and CSO.
(3) Narrow linearity width (Type≤0.35MHz), low noise, DFB continuous wave laser.
(4) SBS: 13~19dBm continuous adjustable.
(5) ITU-TG.692 Wavelength can be adjustable within the range of ±200GHz (±1.6nm) as ±0.05nm stepping.
(6) AGC/MGC mode is optional and OMI can be optimized.
(7) Automatic temperature control.
(8) Dual pluggable power supply.
(9) With RS232 communication interface, SNMP remote monitoring (support Web browser).
