Product Description
HT1500B
1550nm Direct Modulated WDM FTTX Fiber Optic Transmitter
Product Description
AITC 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.
HT1500BC 1550nm transmitter: CATV wavelength.
HT1500BU 1550nm transmitter: ITU standard wavelength.
Product features
1. Low chirp, high linearity DFB laser.
2. Dual module RF driver, high efficient laser pre-distortion adjustment.
3. Perfect APC, ATC closed loop control.
4. Intuitionistic modulation status display.
5. Built-in dual back-up power supply, switch automatically.
6. Casing temperature auto-control, ensure the long life of the laser.
Main application
1. Provide IP/QAM, VOD value-added service in second-grade service area (Sub-HE).
Analog digital mixed transmit < 15Km. (common distance ≤ 10km).
Pure digital load < 40Km.
2. DWDM narrow band multiplex >70Km
