Product Description

1310nm fiber optical transmitter for CATV net



Description
1310nm direct modulation optical transmitter, adopts high linearity DFB laser of famous brand in the world, and builds-in perfect pre-distortion adjustment circuit and laser APC, ATC closed loop control circuit. All the operating parameters are controlled by microprocessor, and the LCD screen on the front panel can display relative operating select and the fault information.

Characteristic

1. SNMP is available.

2. Build-in perfect pre-distortion circuit

3. Full-automatically (OMI) control, AGC&MGC

4. Front panel has 20 grade OMI status display(Modulation Depth), intuitively adjust and display OMI normal(NOM), low(LOW),high(HIGH) AGC status, RF is fixed OMI is alway sat NOM status. MGC status, OMI can be at NOM status by adjusting ATT

5. Double power supply inside backup, full-automatically switch. switch time≤10us.

6. Full-automatically control of casing temperature by two fans (≥45°C turn on , ≤35°C turn off )

7. Double RF input port AM interface(input 59 routes PAL-D 47-550MHz and digital interface(-10Db input digital video550-750MHz)

8. Time locked function
