CA system RF RF signal light transmitter 1550nm

CA system RF RF signal light transmitter 1550nm I Product Overview Doteck CA Series RF RF Signal Optical Transmitter 1550nm, all uses a world-famous brand high linear DFB laser, a built-in perfect predistortion correction circuit, and a laser APC, ATC closed-loop control circuit. The various working parameters of the whole machine are controlled by the microprocessor, and the relevant operational status and fault information are provided by the front panel LCD screen. It integrates the advantages of various 1550nm direct-modulated optical transmitters at home and abroad. As a high indicator, multi-function, high reliability model, it can be applied to the use of high-end users. II Product Features (1) Dual Module RF Driver, Efficient Laser Predictive Correction. (2) Automatic laser modulation (OMI) control, AGC & MGC intuitive modulation status Display works in AGC state, RF is in the rated input range, and OMI will always be in the NOM state. Working in the MGC status, adjusting the ATT, allowing OMI convenience to NOM state. (3) Built-in dual power support, fully automatically switch the single power supply, then another cool backup. The dual power supply is simultaneously working, and the other is a hot backup, such as one of them, it is automatically switched to another. Switch time ≤10μs. (4) Automatic chassis temperature control, ensuring that the long life of the laser is monitored by the microprocessor, and the display shows the actual operating temperature of the chassis at the time. When the chassis temperature is higher than the set value (45 ° C), the two high-efficiency axial fans of the rear panel will be automatically opened, and forced cold. When the temperature falls to the set value (35 ° C), it will automatically stop and extend the life of the fan. (5) RF input port AM interface Enter 59 Road PAL-D (47 ~ 550MHz) (6) Time Locking Function With Time Control and Locking Function, users can set machine working hours by software at the front panel (such as three months ), More than the set time, the machine will prompt the alarm, do not enter a password, the machine will automatically shut down.
