The DMLT-1550-SA series of laser transmitters are designed to perform RF signal to optical conversion from 10 MHz to above 2,400 MHz. The DMLT-1550-SA series transmitters are low cost and high performance products that can be used for L-Band Analog and 36-Channel satellite IF signal distribution in optical fiber networks. It can also be a ideal transmission solution for any RF, microwave signal over fiber applications.
The DMLT-1550-SA transmitters incorporates direct modulation that allows the transmission frequency range to be extended up to 2,500 MHz. With a narrow linewidth DFB laser source, it is capable of transmitting 20 km kilometers in single mode fiber, while maintaining a high CNR and excellent IM2 and IM3 performance. The DMLT-1550-SA transmitters can be utilized in IF link, mobile signal link applications. QAMnet EMLT-1550-SA transmitters are available in two output power level versions: +6 dBm and +8 dBm.
