JUNE 26, 2008 -- Aurora Networks (search for Aurora Networks) has expanded its family of Light-Plex integrated optical narrowcast demuxplexers and broadcast/narrowcast combiners. The company's new OP4528 features built-in optical power level management capabilities, which Aurora asserts will simplify the installation, set up, and maintenance of "fiber deep" DWDM architectures.
Aurora designed the OP4528 for installation in its VHub, which serves up to 20,000 homes in a standard node housing. As cable operators add new video or data carriers, they can use the OP4528 to realign power levels remotely via an SNMP interface to an element management system. Previously, operators needed to coordinate a headend tech and field tech to simultaneously set up the link. The OP4528 also enables cable operators to add optical wavelengths without interrupting existing narrowcast services to their subscribers, Aurora says.
The OP4528 features four optical input ports for broadcast and narrowcast services. Nine output ports are available (one port for narrowcast services passthrough and eight combined broadcast/narrowcast ports). Each combined port delivers unique content to its related service area. Each OP4528 demultiplexes up to eight DWDM wavelengths and is available in five ITU wavelength groups. Up to three OP4528s can be installed in a single VHub to generate up to 24 unique service areas.
