1550nm External Optical Transmitter

This series internal-modulated transmitter performs RF-to-optical signal conversions in 1550nm transmission link.

1U 19’ standard case with liquid crystal display (LCD/VFD) in front panel;

Frequency bandwidth: 47—750 / 862MHz;

Output power from 4 to24mw;

Advanced pre-distortion correction circuit;

AGC/MGC;

Automatic power control (APC) and Automatic temperature control (ATC) circuit.

 

Feature

Both the external modulator and laser are imported from the United States or Japan.
Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in highstandard.
Perfect SBS suppress circuit and adjustable SBS in 13,16, 18,suitable for different types ofCATV net.
AGC control.
Internal double power which can be changed automatically.
Automatically shell temperature control.
Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
