Optical Transmitter 10dBm External Transmitter1550nm Fiber Optic Transmitter

 Optical Transmitter 10dbm External  Transmitter1550nm Fiber Optic Transmitter  Product DescriptionBrief IntroductionThe transmitting modules of this machine adopt the imported DFB laser named Agere (ORTEL, Lucent), Mitsubishi, Fujitsu, AOI, and so on.The internal RF driving amplifier and controlling circuit of this machine can ensure the best C/N.The perfect and stable circuit of optic power output and controlling circuit of the thermoelectric refrigeration device of the laser module assures the user of the best quality and stable working for a long time. The internal microprocessor software has many functions such as laser monitoring, number display, trouble alarm, and on-line management.Once the working parameter of the laser is out of the fixed range, there will be a red light glistening to alarm. The RS-232 standard connector makes it is possible to manage online and monitor in another place. The machine adopts a 19" standard shelf and it can work with the voltage from 110V to 254V.Applications •Used in main links and distribution network links in large and middle CATV station head-end. Analog-digital hybrid transmission >200Km (with dispersion compensation). Pure digital transmission (without dispersion compensation) >400Km, (with dispersion compensation) >700Km. •ST1550EU ITU wavelength adjustable, applicable to the value-added service of DWDM fiber optic CATV system and CFG dispersion compensation system. •It can be used in branch FTTH that has high system index demand. Point to Point>65Km, CSO ≤ -65dB. It can provide highly qualified and reliable value-added service such as RFTV, IPTV, and VOD for the secondary users. It can also avoid the limitation of CSO deterioration and transmission distance caused by laser chirp for adopting a 1550nm direct modulated optical transmitter.Product Parameters Performance Index Supplement               Optic Feature Operating wavelength (nm) 1548~1563 ST1550EC ITU-TG.692 ST1550EU Wavelength ADJ. range (nm) ±1.6(±200GHz) ST1550EC Wavelength ADJ. mode   ±0.05nm stepping ST1550EU Wavelength stability (Pm/ºC) -1~0 Tc=20~70ºC Linewidth (MHz) Typ.=0.65 FWHM(△λ), (-3dB fullwidth) Side mode suppression ratio (dB) ≥45 SMSR Equivalent noise intensity   ≤-160 RIN(20~1000MHz) Number of output port   2 Optional4,6 Output power (dBm) 10, 8.5, 7.0, 4.5 2×7, 2×9, 2×10, 2×5, 4×7,6×7 Return loss (dB) ≥50   Optical connector   FC/APC Optional SC/APC, LC/APC       RF Feature Work bandwidth (MHz) 47~862   Input level (dBmV) 18~28 AGC Flatness (dB) ≤±0.75 47~862MHz Return loss (dB) >16   Input impedance (Ω) 75   RF port   F-Female           Link Feature Transmit channel   PAL-D/60CH PAL-D/99CH   CNR1 (dB) ≥53.0 ≥51.5 Back to Back CNR2 (dB) ≥51.5 ≥49.5 65Km optical fiber, 0dBm receive CTB (dB) ≥-65 ≥-65   CSO (dB) ≥-65 ≥-65   SBS restrain (dBm) 13~18 Adjustable               General Feature SNMP network management interface   RJ45   Communication interface   RS232   Power supply (VAC) 90~265 50/60Hz (VDC) -48 30~72VDC Power consume (W) 50 Single power works Work temp.
