Product Description

The chirp makes severe distortion at ***0nm and becomes more serious as increase of transmitting distance, transmitting bandwidth and channel numbers. For this reason, this device adopts high linear and low chirp DFB laser which add predistortion and chirp compensation based on ***0nm multifunctional optical transmitter for improving transmitting index of system effectively. It is available for optical transmitting of ***0nm analog and digital multiplex channels signal in *0Km. Moreover, it also can be used for narrow wave reuse of DWDM and IP/QAM. This device adds DWM insert filter and adjustable optical attenuator for adding insert function at ***0nm conveniently. That can automatically complete insertion of optical power in accordance with wavelength carrier number of optical signal and level of main optical power wavelength (network management included), which resolves insertion power and level changes after using. Main wave is ***5�***5nm, insertion is laser wavelength of device.
