激光發(fā)射機(jī) 衛(wèi)星鏈路發(fā)射機(jī)+6dBm-單輸出 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 | | | | | | | | | 會員1.png)
