Aurora Networks touts segmentation toolkit for cable operators

Cable operators increasingly are looking at node segmentation as a way to increase capacity on their networks. Aurora Networks, Inc. is positioning itself as a one-stop shop for cable MSO segmentation requirements. The company says its segmentation toolkit includes can address both the downstream and the upstream paths, including a line of optical passives that enables full downstream and upstream segmentation for multiple nodes on a single fiber.

The toolkit certainly contains a wide variety of products. In the downstream direction, the kit includes:

  • AT3545G C-Band DWDM full spectrum transmitters: The transmitter family is designed to work in multiple applications, from transmission of up to 120 narrowcast QAM channels in the 300 MHz to 1 GHz frequency band in a broadcast/narrowcast overlay architecture, to a full spectrum transmitter application. The ability to evolve networks to full QAM capabilities can enable a seamless migration for future Converged Multiservice Access Platform (CMAP) deployments, Aurora Networks states. Elements of the AT3545G line can support up to 16 wavelengths per fiber in full spectrum applications over 60 km.
  • Broadcast and narrowcast overlay: This capability supports up to 40 narrowcast wavelengths alongside broadcast services on a single fiber and provides extended reach.
  • LcWDM O-Band full spectrum transmitters: The LcWDM line supports as many as eight wavelengths for shorter-reach applications.

Aurora Networks complements these capabilities with a pair of node platforms, the NC4000 and the NC2000 Optical Node Platforms. The compatible platforms share the same modules, including the company’s Node PON and Fiber on Demand modules. The NC4000 Optical Node Platform supports 4x4 segmentation, while the NC2000 Optical Node Platform offers 2x2 segmentation, with an evolutionary path towards RFoG, RFPON (RFoG plus PON), and GEPON.

In the upstream direction, Aurora Networks touts its digital return technology, which supports more than 80 return segments per fiber. The company also offers a 15-wavelength CWDM capability and a 40-wavelength DWDM option.

“A proper segmentation strategy exploits the existing network resources to maximize bandwidth-per-subscriber while minimizing capital expenditure. This enables cable operators to achieve a new level of quality-of-experience for the subscriber,” said John Dahlquist, vice president of marketing for Aurora Networks. “Aurora’s product breadth enables our network architects to evolve our customers’ networks, attaining their service goals without wasteful overspending.”
