Junpu 20km Internal 1550nm Optical Transmitter 10dbm 1 Output SC APC

Junpu 20km 1550nm Internal Optical Transmitter 10dbm 1 Output SC APC

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.

Junpu JP1510DT is a 1550nm direct modulation optical transmitter with high index and AGC function. It adopts high linearity and low chirp DFB laser, built-in pre-distortion compensation and AGC, APC, ATC closed loop control, which improves the system index obviously. JP1510DT direct modulated optical transmitter can be used in WDM narrow-band multiplexing and IP/QAM.

1550nm directed modulation optical transmitter max support 20km transmission distance.
If more than 20km, then it should be 1550nm extener modulated optical transmitter.
