1550nm direct internal modulated transmitter module
1. Imported JDSU, Ortel high linearity DFB laser, fully guarantee the quality of the link performance.
2. The superiority of APC(automatic power control),ATC(automatic temperature control)function, to ensure the stability of laser output power and laser operating life.
3. The superiority of RF channel with AGC control circuit, which can accommodate a wide range of RF input signal.
4. Perfect pre-distortion circuit to guarantee the perfect CTB and CSO when C/N in high standard.
5. The standard RS-232 and RJ45 interface, convenient for computer network management.
