HT1500B is a direct modulation 1550nm transmitter with high index and without 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. The 1550nm transmitter can be used in FTTx (≤10Km) of second-grade service area (Sub-HE), and can also be used in WDM narrow-band multiplexing and IP/QAM.
