Description

1550nm CATV Optical Transmitter 25km, 8-6dBm Dual Power TX1550nm Direct Internal Modulation.

(Satlink Brand)

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 1550 nm external modulated transmitters and dispersion effects of 1550 nm directly modulated make network transformation difficult. Thus, we create the 1550nm directly modulated optical transmitter with electronically controlled dispersion compensation.

It supports up to 1.2 GHz band and a CATV HFC system. With two RF inputs and high isolation, it enables the signal transmission of QAM and IPQAM smoothly. Support a transmission distance of 50 km with electronically controlled dispersion compensation. Built-in CWDM is optional for multi-wavelength networking.
