10dB CATV 1550nm optical transmitter

According to the Next Generation Broadcasting (NGB) planning and PON standards, 1550nm is defined as the transmission wavelength for HFC downstream. The high cost of 1550nm external modulated transmitter and dispersion effects of 1550nm directly modulated make network transformation difficult. Thus we create the 1550nm directly modulated optical transmitter with electronically controlled dispersion compensation.

It supports up to 1.2GHz band and DOCSIS 3.1 system. With two RF inputs and high isolation, it enables the signal transmission of QAM and IPQAM smoothly. Support a transmission distance of 50KM with electronically controlled dispersion compensation.

Features:

1.2GHZ band, support DOCSIS 3.1 system.
The AGC and MGC gain control modes are optional.
Two inputs with 50dB isolation for high quality RF insertion.
Dual power supply; hot backup; a variety of power supply options are available, optional AC220V and DC48V.
Laser output power, bias current and cooling current are detected in real time.
Optional CWDM for optical signal insertion.
Electronically controlled dispersion compensation can support a transmission distance of 50KM.
Low-cost solution is comparable to the performance of external modulated transmitter.
ITU standard wavelength is optional.
