I. Main Technical Characteristics
The transmitting modules of this machine adopt the imported DFB laser named SEI and so on.
The internal RF driving amplifier and controlling circuit of this machine can ensure the best C/N. The perfect and stable circuit of optic power output and controlling circuit of thermoelectric refrigeration device of laser module assure the user the best quality and stable working for a long time.
The internal micro-processor software has many functions such as laser monitoring, number display, trouble alarm and on-line management. Once the working parameter of the laser is out of the fixed range, there will be a red light glistening to alarm.
The RS-232 standard connector makes it is possible to manage on line and monitor in another place.
The machine adopts 19"standard shelf and it can work with the voltage from 110V to 254V.
II. Display Board Operation Guide:
Press the button "Status" in the board, the working parameter of this machine can be seen in turn as follows,
1.Model:ST1550I-02,04,06,08,10,12
2.Output Power: display the output power of this machine(mW).
3.Laser Temp: the laser works between 20ºC and 30ºC.If the temperature is out of this range, the red light will glisten to warm.
4.Bias Current: The bias current of the laser is the main working parameter of the laser. Only when the parameter is above 30mA, RF driving circuit can begin to work. The red light will shine to warn when the RF driving level comes out of the fixed value.
5.REFRG Current:showing the working current of heating or cooling which can make sure the standard temperature is 25ºC.
6.+ 5V test(Reads):showing internal actual Voltage of ±5V.
7.- 5V test(Reads):showing internal actual-5V.
8.+24V test(Reads):showing internal actual voltage of+24V.
