According to the TUOLIMA planning and PON standards, 1550nm is defined as the transmission wavelength for HFC downstream.

The high cost of 1550nm optical amplifier 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. This fiber transmission equipment supports up to 1.2GHz band and DOCSIS 3.1 system.

With two RF inputs and high isolation, 1550nm fiber amplifier enables the signal transmission of QAM and IPQAM smoothly. Support a transmission distance of 50KM with electronically controlled dispersion compensation. Built-in CWDM is optional for multi-wavelength networking.
