激光发射机 双波段CATV+卫星发射机+8dBm-双输出 The EMLT-1550-DB series of laser transmitters is designed for use with dual-bａnd transmission applications. Based on our proprietary design, the EMLT-1550-DB operate as two sets of laser transmitters with 1U rack mount chassis. There are two transmission bands: a CATV bａnd and Satellite band. The CATV bａnd transmitter operates as a standard HFC laser transmitter with a frequency range from 45MHz to 860MHz. It is designed for electrical to optical conversion of CATV signals such as AM-VSB, FM and QAM signals. It can transmit up to 65km in distance, while providing excellent CNR, CSO and CTB performance. The Satellite bａnd transmitter can perform electrical to optical conversion from 950MHz to 3,000MHz, EMLT-1550-DB can also be used for transmitting DTH, Satellite, IF and other RF modulated signals over optical fiber. EMLT-1550-DB series is highly versatile, and is a cost-effective transmission solution for RF signals over optical fiber applications. They are available in two distinct output power versions: +6dBm / +8dBm single output. Features: - Slim 1U height rack mountable housing - High power, narrow linewidth DFB laser module - Broadbａnd external modulator - Dual-bａnd transmission: * CATV: 45MHz to 860MHz for analog and QAM channels * Satellite: 950MHz to 3,000MHz for DTH and Sat/IF - SBS suppression level: +13dBm to +16dBm (optional) - Separate input port for CATV Bａnd and Satellite Bａnd - 65km standard transmission range - AGC (Automatic Gain Controls) Input Control for CATV band
