1550 nm Optical Amplifier
The Harmonic MAXLink™ transmission system is a family of transmitters and optical amplifiers
designed for 1550 nm-based network applications. The MAXLink system provides a cost-effective
solution for a variety of applications and architectures, including long haul applications and
fiber dense architectures which take advantage of high power optical amplifiers. In addition,
this system is ideally suited for new, evolving transport architectures such as redundant
rings, broadcast layer transmission, and hub interconnects used in broadband networks.
The MAXLink product line consists of rack mount modules for 19” racks, including the HLT series of
broadcast optical transmitters as well as a full range of HOA series of optical amplifiers. Full monitoring and
configuration are available through the embedded SNMP agent and HTTP server.
The HOA 7326 Optical Amplifier is optimized for use with the Harmonic MAXLink product line. The amplifier
was designed primarily for deep fiber architectures that require high optical power in the distribution
section of the network. A typical application is shown below.
