Product Description

Brief Introduction

The 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.

Features

•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.
