PETALUMA, Calif.--(BUSINESS WIRE)--KDDI R&D Laboratories (KDDI R&D), Furukawa Electric Company Ltd. (Furukawa), and Teknovus today announced an end-to-end fiber-based backhaul transport solution that eliminates the need for costly GPS receivers at each base station throughout the cellular network. The solution integrates one GPS receiver with the OLT (Optical Line Terminal), distributing carrier-grade clock signaling throughout the EPON network to every connected base station. Service providers can now support backhaul traffic without the need for costly GPS receivers and cabling and monthly TDM-circuit fees, reducing CAPEX and lowering OPEX by 25-30% or more. In addition, this solution enables base station installations in areas with limited GPS reception, such as those shadowed by adjacent buildings or other physical obstructions.

Accurate clock synchronization is required in cellular networks to prevent call drops as subscribers move from cell-to-cell, to ensure high-quality voice communications and to support accurate billing. Without this combined KDDI R&D/Furukawa/Teknovus solution, carriers must either deploy costly GPS receivers at every base station or lease expensive TDM circuits for backhaul communications (base station to cellular network control center).

This end-to-end clock synchronization solution is based on:

• Teknovus Turbo-EPON^TM chips and embedded software. Teknovus EPON chips are the industry leader in high-integration and low-power for fiber-based networks.
• Furukawa’s integrated GPS receiver for the OLT, which multiplexes the clock signals into EPON frames using the Teknovus OLT chip. For base stations, Furukawa provides an SFP-ONU (Small Form Factor Pluggable-Optical Network Unit), the FITELwave AG9, based on the Teknovus ONU chip, which de-multiplexes the clock signals with high fidelity for use by wireless base stations.
• KDDI R&D’s timing solutions for fiber-based networks, which eliminate the need for costly GPS transceivers at every base station.

Together, the combined solution offers all of the benefits of Teknovus’ EPON chips with the flexibility of Furukawa’s SFP-ONU, and inexpensive timing solutions from KDDI R&D.

Come and see our EPON solutions for wireless backhaul at OFC – Booth 3149 – in San Diego this week.
