AHOT500 19”1U 1550nm direct optical transmitter is a laser transmitter with high reliability, high quality and high practicality. This product adopts international standard 19”1U rack, during 1550nm short range transportion, it can replace external optical transmitter with high price. It adopts SBS restrain technology and SS Spectral Shaping, with high SBS threshold level, CTB index, and CSO index. Meanwhile, brief structure, low cost and high reliability.
During 1550nm whole net overlap, we can use its overlay technology to achieve local own program, IPQAM, Cable Modem narrow wave access, HDTV mutual demand and other value added services, to achieve duplexing of HFC network.
•Adopt imported DFB laser with low noise as light source, most output can reach 16mw.
•Excellent predistortion design, there is wonderful CTB and CSO index while high standard CNR.
•Excellent automatic gain AGC control, to maintain quite output function as different RF input.
•VFD or LED revealing, with laser control, digital revealing, fault warning, network management; once laser’s work index deflect permit, will alarm.
•Standard RS-232 interface, used for local network’s management and monitoring.
•Standard RJ45 interface, supporting SNMP、used for distant management.
•Excellent switch power, worked in 90V～265V AC or -48V DC.
