Product Description
1550nm Direct-Modulation Optical Transmitter

AOT155D-41 is a kind of direct-modulated optical transmitter with 1U 19" standard rack. On the front panel, there is a RF test port, two LEDs for power supply, one LED for status, LCD screen and four buttons. On the back panel, there is a fan, F type connector, optical input port and optical output port. It is convenient to install and maintain. AOT155D-41 is mainly applied in 1550nm inter-cut system. It supports ITU standard wavelength. Input level can be controlled by AGC or MGC. Full intelligent design, all the functions can be completed automatically. Status and functions can be monitored and controlled by local control module or SNMP NMS. 

1.1U 19" standard rack
2. Operating Bandwidth 47~870/1000MHz.
3. With inter-cut device, when the power of main path is too low, it will close the optical inter-cut function
4. Integrate electrical control inter-cut function, can set inter-cut tuning by LCD or NMS
5. Shows working status on LCD, including optical power, bias current, laser temperature, cooling current, inter-cut setting and so on.
6.1550nm DFB lase with ITU wavelength. Adjustable optical output power
7. Build-in multiplexer, adjustable wavelength
8. Network management complies with SNMP protocol, support WEB management function
9. Support dual hot-swap power supplies, 220VAC and 48VDC
10. AGC/MGC in RF path. Use integrated digital attenuator to achieve optimal link performance, adjustable gain of data channel
11. Patented pre-distortion technique to get excellent non-linear distortion index
12. Intelligent design, parameters can be set locally or remotely.
