OPTICAL TRANSMITTER 1310NM  VTS HT-8300

• Dual Module RF drive, high efficiency laser pre-distortion adjustment.
• Full-automatically optical Modulation Intensity (OMI) control, AGC&MGC.Under AGC select, input range is 78dBuV~88dBuV, system index is optimum. Under MGC select, input range can be adjusted 75dBuV~90dBuV by the ATT on front panel.
• Front panel has 20 grades OMI select display (Modulation Depth). Under AGC select, within RF range, OMI is always at NOM select. Under MGC select, OMI can be at NOM select by adjusting ATT.
• Dual power supply inside backup. Full-automatically switch. One is working, the other as cool backup (suggested). Both are working at the same time, one as hot backup. If one is damaged, switch to the other full-automatically. Switch time≤10us.
• Full-automatically control of casing temperature, ensure long life of the laser. Casing temperature is monitored and controlled by micro-processor. Display screen shows the actual operation temperature in time. When casing temperature≥45°C, Two fans at the back panel will open automatically to cool it by constraint. When casing temperature≤35°C, the transmitter will turn down automatically to ensure longer life of the fans.
• RF input port. AM interface Input 59 routes PAL-D (47-550MHz)
• Time locked function. HT8300, with time control and lock function, user can set the working time (eg, 3 months) by the software on the front panel. If exceeding the fixed time, there will be alarm, only the password can turn on the machine again otherwise it will turn off automatically
