1550nm External Modulation Optical Transmitter

Overviews

OT1500E is a high performance external modulation 1550nm optical transmitter with LiNbO3 external modulation and a high power , low noise DFB laser . It adopts a series of unique innovation technique to reach the excellent systerm control . With 47~862MHz bandwidth, SBS is 13,16,18, suitable for different types of CATV .

Feature

• Low chirp, high linearity DFB laser, chirp compensation.
• Full-automatic OMI control, AGC & MGC.
• Dual module RF driver , high efficient laser pre-distortion adjustment.
• Intuitionistic modulation select display.Built-in dual back-up power supply, switch automatically .
• Casing temperature auto-control, ensure the long life of the laser.
• Both the external modulator and laser are imported from the United States or Japan.
• Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
• Perfect SBS suppress circuit and adjustable SBS in 13,16, 18，suitable for different types of CATV net.
• Internal double power which can be changed automatically.
• Automatically shell temperature control.
• The transmitter provides RJ45 and RS232 standard interface for Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
