10dbm 1550nm Optical Transmitter / Catv Laser Transmitter In Directed Modulation
Description
Direct modulation will lead to high laser chirp (Laser's bias current is modulated by signal and the optical spectrum shifts and shakes). Laser chip will interact with dispersion effect caused by standard single mode fiber (SMF-28), which will generate serious distortion in the place of 1550nm. This kind of distortion will become more serious with the increase of transmission distance, bandwidth and channel number.
Product Features
●Low chirp, high linearity DFB laser, chirp compensation
●Full-automatic OMI control, AGC & MGC
●Intuitionistic modulation status display
●Built-in dual back-up power supply, switch automatically
●Casing temperature auto-control, ensure the long life of the laser
