HCTA Expands Salira Line with New Optical Network Units

Hitachi Communication Technologies America (HCTA) has launched the 10G DePON and 10GEPON optical network units under the Salira product family. The new products provide fiber access infrastructure that can support today’s bandwidth requirements of cable operators. The company will showcase the 10G-DePON from May 11 to 13 at the Cable Show in Los Angeles. In addition, HCTA will demonstrate the DePON at the show.

The business applications such as 3DTV, cloud computing, gaming, MEF services, HDTV, videoconferencing, rich media files and transparent LAN services are straining the currently available access technologies. Moreover, having higher bandwidth along with other solutions is not cost effective when deployed in wide-scale applications. The 10G DePON provides solution to these problems by offering a combination of effective service control, lower cost, and high bandwidth. This enables the cable operators to run large-scale, profitable residential and business services.

The DOCSIS control of the 10Gbps infrastructure is the result of the integration of IEEE GEPON physical layer with the DOCSIS management. The company’s strategy for leveraging the current standards based equipment to migrate efficiently to fiber access from HFC included the reusing of DOCSIS management together with the 10Gbps fiber access. The IEEE 802.3av standard provides support to 1Gbps upstream and 10Gbps downstream or symmetrical 10Gbps transmission.

HCTA chose the 10GEPON wavelengths in order to make sure that it coexists with the currently available RF video and GEPON. The allocation was done to facilitate support for the asymmetric 10Gbps/1Gbps ONUs and symmetric 10Gbps/1Gbps ONUs. The allocation was also for the RF video overlay over the same network of optical distribution.

The company had deployed its equipment to support a large EPON network cable operator in the U.S. This deployment demonstrates that 10GEPON facilitates operators to offer services to the residential and business subscribers at a reasonable cost.

The President of the HCTA’s Salira Division, Takashi Mori said that the company believes the 10G-DePON to become a core technology for cable operators and help them build new access networks with increased bandwidth.
