Mini Optical Receiver With WDM

•High performance: Externally modulated technology, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz. •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 47~862MHz (47~1080MHz). •CNR ≥ 53dB and excellent CTB, CSO index. •SBS: 13~18dBm adjustable. •ITU standard wavelength, ±200GHz (±1.6nm) adjustable. •AGC/MGC mode is optional at the spot. OMI can be optimized at the spot. •Perfect RS232 communication interface. •Advanced SNMP network management function. •1+1 power supply backup, switch automatically. •Casing temperature auto-control.

•Excellent P/P ratio.

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.
