Harmonic's 'Outdoor Hub' turns nodes into hubs
Harmonic is introducing what it's calling an Outdoor Hub, a system that cable network operators can use to extend fiber deeper into neighborhoods, and which can be installed in common cable node housings.
Harmonic designed its Outdoor Hubs to be configurable for a variety of functions, depending on which combination of modules each is equipped with. There are modules for optical switching, splitting, amplification, wavelength multiplexing and de-multiplexing, and re-lasing.
Since these modules are compatible with existing optical node housings, operators can expand their existing nodes to Outdoor Hubs, which can then serve additional nodes. An optional DOCSIS or HMS status-monitoring transponder enables remote monitoring and control of all functionality in the Outdoor Hub.
When combined with Harmonic's SupraLink 1550 nm transmission solution, the Outdoor Hub simplifies architecture and streamlines day-to-day operations, reducing capital and operating expenses, the company said.
Pushing fiber deeper increases bandwidth efficiency, enabling operators to deliver improved high-speed Internet, cable IPTV and multi-screen services over their existing networks, Harmonic explained.
"In the past, cable service providers have constructed new buildings or climate-controlled vaults to house similar optical network functions. Such practices are expensive and delay service activation due to the need for obtaining building permits," said Gil Katz, vice president of cable solutions at Harmonic. "With the Outdoor Hub, operators now have the option of using a node enclosure to grow their networks, thereby minimizing capital expenditure and speeding up service delivery."
