At the ANGA COM DIGITAL conference (June 8-10), Teleste has introduced two new high-performance nodes to complement the company’s offering of devices for distributed access networks.
With distributed access deployments gradually growing in the cable industry, the company says the devices, the AC9400 node and the DAN3 RPD, have been designed to enable a smooth technology transition for operators currently advancing their roadmaps of next-generation broadband services.
The DAN3 is billed as a compact, smart and segmentable Remote PHY node (RPD) that is designed and optimized for deep fiber networks and MDU environments. Meeting CableLabs specifications, the DAN3 RPD ensures interoperability between core solutions from different CCAP vendors without requiring specialized development or back-office upgrades.
According to its manufacturer, the DAN3 RPD supports full spectrum downstream capacity up to 1.2 GHz and it has a single downstream and two upstream segments. This allow operators to operate the node in the 1x1 mode with a 1x2 RPD module installed, and enable the 1x2 mode later when the needs for upstream capacity grow. A configuration change between 1x1 and 1x2 modes can be done remotely without visiting the site, notes Teleste.
"The high-performing DAN3 introduces an elegant design in a compact housing, making it an ideal solution for installations where high performance and small size are paramount," adds the company.
For its part, the AC9400 is billed as an intelligent, DOCSIS 3.1 capable node that supports the Remote PHY upgrades with a separate RPD lid that ensures interoperability with different CCAP cores.
The innovative technology used in the AC9400 Remote PHY Ready node is familiar from Teleste’s previously launched optical nodes; the company says the new product has been designed with operational flexibility and smooth technology migration in mind.
Optimized to support upcoming infrastructure upgrades, the company contends that with the AC9400, operators will "be able to benefit from excellent fiber node capabilities today, and securely switch to distributed access solutions when needed." Also, the company notes that RF overlay is possible for both signal directions in the unit's RPD operation.
Finally, the AC9400 node can be equipped with a transponder module, which allows full remote monitoring and control of all node parameters. The transponder unit measures the forward and return path signal levels and enables the automatic downstream and upstream alignment function.
"This makes the node an excellent fit for networks where future-proof operation is desired in terms of both network architecture and ensured quality of services for subscribers," adds Teleste.
