Harmonic 7205 Return Transmitter (1549.32nm)

Harmonic’s METROLink HLD 7205 is a family of high performance DFB laser transmitter modules designed for return path narrow casting applications. The DFB laser’s wavelength is stabilized and aligned to one of eight wavelengths on the ITU grid with 200 GHz (1.6 nm) spacing. By using Dense Wavelength Division Multiplexing (DWDM), multiple return path signals can be carried on a single fiber. The HLD 7205 transmitters can operate alone or in combination with Harmonic’s METROLink family of gain flattened optical amplifiers, and DWDM multiplexers and demultiplexers for complete system solutions.
