激光发射机 卫星链路发射机+6dBm-单输出 The EMLT-1550-SA series of laser transmitters are designed to perform RF signal to optical conversion from 10MHz to above 3,000 MHz. EMLT-1550-SA series transmitters are low cost and high performance products that can be used for 36-Channel QAM satellite signal distribution in optical fiber networks. It can also be a ideal transmission solution for any RF, microwave signal over fiber applications. EMLT-1550-SA transmitters incorporate a broadbａnd external modulator that allows the transmission frequency range to be extended beyond 3,000MHz. With a narrow linewidth DFB laser source, it is capable of transmitting 65km kilometers in single mode fiber, while maintaining a high CNR and excellent IM2 and IM3 performance. EMLT-1550-SA transmitters can be utilized in IF link, signal link applications. EMLT-1550-SA transmitters are available in two output power level versions: +6 dBm and +8 dBm. Features: - High Power DFB Laser - Broadbａnd External Modulator - SBS suppression level to +13dBm - 65km standard transmission range - Supports 36-Channel QPSK Satellite signal - MGC (Manual Gain Controls) RF Input Control - 10 - 3,000 MHz Modulation Bandwidth Technical Specifications Model Number EMLT-1550-SA-06 Technical Specifications Transmission Range Up to 65km Laser Wavelength Range 1550nm ± 10nm (standard), available with 40 DWDM wavelengths Optical Output Power 6dBm minimum Number of Optical Output 1 Noise Bandwidth 16 MHz Carrier Noise Ratio (CNR) > 40dBc for 36 channels SAT/IF Composite Second Order (CSO) N/A Composite Triple Beat (CTB) N/A SBS Suppression Level +10dBm to +13dBm RF Gain / OMI Adjustment Range N/A Input RF Power Level N/A Frequency Plan 36-Channel QAM Satellite Signal RF Frequency Range 10MHz - 3000MHz Flatness in Frequency Range +/- 1.0dB Input RF Impedance 50 Ohm Input RF Return Loss 13 dB minimum Mechanical Specifications Operating Temperature Range 0°C to +50°C Storage Temperature Range -40°C to +70°C Power Consumption 50W maximum Power Supply 80 -240 VAC, 43 - 62 Hz Housing Dimensions 19″ x 14″ x 1.75″ Front Panel Display LCD Control / Monitoring DFB laser temperature, output power Alarm Status Over temperature, over current Optical Connectors F Type
