Harmonic debuts digital DWDM return path solutions for nodes
LOS ANGELES-Harmonic Inc. has announced digital dense wavelength division multiplexing return path solutions for several of its PWRBlazer nodes, providing operators with flexible and robust return of data over hybrid fiber/coax networks, according to company officials. By locating digital DWDM return functionality in the node, the company is simplifying network design, reducing power consumption, and enabling low-cost passive optical hubs. The digital DWDM return transmitter being introduced allows for up to 16 return streams to share a single fiber link, providing ample return bandwidth for high-speed Internet access, video-on-demand and other interactive services.
Harmonic's return path transmitters support a variety of network architectures. Digital DWDM return is suited for those architectures with hubs that are kept as small and passive as possible, according to the company.
Harmonic has also announced a NetMentor compatible transponder for its HLN3844 Scalable Node, the NMT5044C, that was developed under a technology partnership entered with Cheetah Technologies in May 1999.
The co-developed transponder will be available as a pre-installed option in the HLN3844 Scalable Node, and can also be easily installed in those nodes already in the field. The transponder is scheduled for availability in the first quarter of 2000. |
