Hybrid fiber-copper access distribution point combines GPON/G.fast technologies

Telnet Redes Inteligentes S. A. has introduced its Hybrid Fiber-Copper Access Distribution Point (HFCA-DP), and says the platform is the first to combine GPON and G.fast distribution point equipment (DPE) capabilities in a manner fully interoperable with Alcatel Lucent and Huawei GPON optical line terminals (OLTs).

Telnet Redes Inteligentes S. A. (Spain) has introduced its Hybrid Fiber-Copper Access Distribution Point (HFCA-DP). The company says the platform is the first to combine GPON and G.fast distribution point equipment (DPE) capabilities in a manner fully interoperable with Alcatel Lucent and Huawei GPON optical line terminals (OLTs).

The DPE also can be used in WDM-PON architectures, Telnet adds. "Companies like Telefonica, a Telnet GPON customer, are among the nearly 60% of those OLT users that can benefit from the new Telnet product," the company said in a press release announcing the new platform.

As previously reported by our sister site Lightwave, the platform leverages G.fast chips from start-up Sckipio Technologies to support 16 G.fast subscribers concurrently. It also includes Telnet's ONT OMCI stack, ITU-T G.984.4, G.984.3, and G.984.2, and VLAN tagging (802.1p and QinQ), enabling it to support the BBF TR-156 recommendation. The HFCA-DP's data path can support 3.75 Gbps and up to 16 subscribers per DPU.

The company says its WDM-PON variant enables central office aggregation of typically up to 40 different optical wavelengths overlaid to GPON optical channels on the same power splitter based optical distribution networks. Each (or several) of these optical channels can be dedicated to a single HFCA-DP system, Telnet says.

The current WDM-PON version of the Telnet´s HFCA-DP supports 32 optical wavelengths (C-Band), each carrying Gigabit Ethernet traffic. However, the system can be upgraded to higher rates, such as. 2.5 Gbps or 10 Gigabit Ethernet, Telnet says. The HFCA-DP also comes equipped with the Telnet GPON SFP ONT to ease integration into existing fiber-optic networks.
