Product Description

Product Characteristic

With pre-distortion compensation circuit, and automatic temperature control (ATC) circuit.
With automatic optical power control (APC) circuit.
RF connector adopts gold plating process, to guarantee the sound connection and high frequency.
Internal low-noise and high power NC gain preamplifier
The laser power can be stabilized automatically, and its operating temperature can be stabilized at the Temperature25+0.5 automatically.
With RJ45 network interface, to realize convenient network management.
Two optional working modes: The automatic mode and the manual mode. Under the automatic mode, it has the following advantages:

A) LCD displays all the parameters of the laser and RF signal
B) Automatic incentive power control. When the number of the program ways is changing, it can adjust the modulation level of the laser automatically, which makes it at the best modulation state.
C) Calibration to the input level and the modulation level of the laser.
D) The modulation level of the laser can be stabilized automatically within the change scope of 15dB input level. Allowable error smaller than 1dB.
E) Enjoys the functions of the off-limits alarming and protection of the input level.
