* Use the international famous brand high performance DFB laser with narrow spectrum, good linearity and high output power.

* RF drive adopting RF power digital automatic process technique, can according to level of input RF signal and number of channels (15-48 channels), automatically processing drive level power, making the C/N, CTB and CSO always in best worth, insure product function; and be steady of output level.

* Advance multi-frequency RF pre-distortion technique with arsenide kalium component availably improves CTB and CSO, the most important parameter of CATV, and heightens C/N at the same time.

* Built-in perfect microprocessor automatic monitor circuit can real-time accurately monitor optical output power and temperature of the laser insure stable optical output power, and prolongs work life of the laser availably.

* Built-in blue VFD monitor on front panel can accurately display the equipment's each work status parameter, and can display error message when the equipment breaks down, make maintenance and fix more convenient.

* 19″1U height standard rack mount, equipped standard RS485 and RS232 network port, can expediently realize monitor through network.
