Detailed Product Description

HT8500AC (CATV wavelength)
HT8500AU (ITU wavelength adjustable)

Standard type Externally Modulated Optical Transmitter (47~1000MHz,CNR1≥53dB,SBS:13,16,18dBm adj.)

Product description

Huatai is the well-known manufacture in analog externally modulated optical transmitter in the world. HT8500A currency standard type externally modulated optical transmitter, take advantage of its high index, high reliability and excellent cost performance, apply to use in the head-end of large and medium-sized CATV station., for the main route network and distribution network.

HT8500AC: Laser adopts 1548~1563nm CATV standard wavelength, dual fiber output.

HT8500AU: Laser adopts ITU standard wavelength, wavelength tunable, dual fiber output. Through the LCD menu in the front-panel, push the button with ±0.05nm adjustable, adjust and set up the laser wavelength around ±200GHz (±1.6nm) , suitable for the network upgrade and expend.
