1550nm Direct Modulated High power Optical Transmitter (Built-in EDFA)
Product description
Huatai HT1500E is a kind of 1550nm direct modulation optical transmitter, built-in EDFA. A built-in EDFA can supply 1~8 way, 13~17dBm output power. It can be used in FTTx (≤10Km) of second-grade service area (sub-headend), also can be used in WDM narrow band multiplex and IP/QAM.
Product features
Dual module RF driver, high efficient laser pre-distortion adjustment.
Intuitionistic modulation status display.
Built-in dual power supply back-up, switch automatically.
Casing temperature auto-control, ensure the long life of the laser.
Main application
Provide IPTV, VOD value-added service in second-grade service area (sub-headend).
Analog digital mixed transmit <15Km. (common distance ≤ 10km).
Pure digital load <40Km.
WDM narrow band multiplex >70Km.
