According to the Next Generation Broadcasting (NGB) planning and PON standards, 1550nm is defined as the transmission wavelength for HFC downstream. 1550nm External Modulated Optical Transmitter is designed for HFC networks applications. It can optionally be equipped with an integrated EDFA for CATV applications.

Fiber optical 1550nm external transmitter’s output from 3dBm~10dBm, and single or dual out for the user’s choice. Hot-plug dual power supply . Automatically shell temperature control.RS232 and RJ 45 for local and remote management.1550nm external modulated is available in a standard 19”,1 rack unit chassis , with dual optical output.
