Product Name: CATV Optical Transmitter 1550nm External Modulation Model NO.: DT-OTEM1500 Interface Type: Sc/APC,LC/APC,FC/APC Feature: 1550nm External Modulation Output: 1 or 2 Port Operation Wavelength: 1540~1563nm Power: 90~265VAC or -48VDC Size: 19''x14.5''x1.75'' Work Bandwidth: 47-862 MHz Output Power: 2 X 7 dBm Trademark: Daytai Transport Package: 1 PC/CTN Specification: CE; RoHs; IOS Origin: Zhejiang, China(Mailand) Product Description 1. DEscriptION OF CATV Optical Transmitter 1550nm External Modulation* Optical Transmitter* 1550nm External Modulation* Output: 1 or 2 port* Output Power:3dBm,5dBm,6dBm,7dBm,8.5dBm...is optional* Operation Wavelength:1540~1563nm* CNR≥52dB,CTB≤-65dB,CSO≤-65dB,SBS:13,16,18dBm Adjustable* Work Bandwidth:47~862,1000,1080MHz is Optional* Connector:SC/APC,LC/APC,FC/APC is Optional* Power :90~265VAC or -48VDC* Size:19''x14.5''x1.75''2. FEATURE OF CATV Optical Transmitter 1550nm External Modulation* High performance: Externally modulated technology for optical transmitter, no laserchirp, low dispersion distortion, high extinction ratio, with excellentcharacteristic within 40~862MHzin-band.* Narrow bandwidth(Typ.=1MHz),lower noise, DFB continuous wave laser.* The operating bandwidth of optical transmitter is up to 47~1080MHz.* Perfect index: Unique innovation technology, provide excellent CNR, CTB, CSO&SBS.* ITU standard wavelength adjustable, the user can adjust and set the laserwavelength on the front-panel with ±0.05nm stepping in the range of ±200GHz(±1.6nm),used in the network upgrading and expansion of WDM system.* AGC/MGC MODE IS OPTIonAL AT SPOT. OMI can be optimized at spot.* Perfect RS232 communication interface.* SNMP network management function optional.* 1+1 backup power supply optional.* Casing temperature auto-control.* Excellent Price-Performance.3. MAIN APPLICATION OF CATV Optical Transmitter 1550nm External Modulation* Used in middle and small CATV center head end, solve thetransmission of trunk and distributive network with high quality and low cost.* Usedin second-grade service area of sub-station. With excellent price-performance, providesecond-grade users with high quality and high reliability value added servicesuch as RFTV, IPTV, VOD and so on. It can avoid the limitation on transmissionbandwidth and distance as well as system CSO deterioration caused by laserchirp for adoption 1550nm direction modulated optical transmitter.4.
