Deutsche Telekom Tests Acacia Communications CFP-DCO

Provider of high-speed coherent optical interconnect products Acacia Communications has announced that Deutsche Telekom has successfully completed its interoperability testing of Acacia’s CFP2-DCO module with Tier-1 switch and router platforms. The testing demonstrated line-side interoperability over 1,500 km of long-haul distance using Acacia’s CFP2-DCO module, demonstrating how 100G coherent DWDM line-side interoperability and standardised pluggable DWDM coherent optics can help significantly improve the flexibility of next-generation packet-optical transport networks.

Testing was completed as part of Deutsche Telekom’s coherent technology qualification due-diligence ahead of deployment activities for metro core and long-haul applications. During the 100G coherent interoperability test, Acacia’s CFP2-DCO module demonstrated multivendor interoperability with several Tier-1 switch and router platforms.

“Interoperability gives us the freedom to choose the best router fit for each particular application,” said Axel Clauberg, Vice President, Aggregation, Transport, IP (TI-ATI) & Infrastructure Cloud Architecture at Deutsche Telekom AG. “We believe that Acacia’s CFP2-DCO coherent module will help to enable the transformation of the telco industry toward a modern, IP and cloud-based production, and significantly reduce production costs through the use of open source and open hardware. We can now use this technology to interconnect with external networks like peering partners at 100G.”

“Standard-based interoperability at the optical transport layer where 100G coherent DWDM transceivers reside is relatively new,” added Fenghai Liu, Associate Vice President, Product Line Management, Acacia Communications. “However, we are increasingly seeing this as the preferred solution and minimum requirement from network operators. Deutsche Telekom’s successful interoperability testing of Acacia’s CFP2-DCO pluggable module over a 1,500 km long-haul distance demonstrates its interoperability capabilities with other platforms to facilitate network simplicity and optimisation.”

The CFP2-DCO product family supports four times the faceplate density of CFP-DCO. With support for 100 Gbits/s using QPSK modulation and 200 Gbits/s using either 8QAM or 16QAM, the module offers enhanced flexibility in a pluggable coherent solution. The module incorporates Acacia’s Meru DSP ASIC, based on 16 nm CMOS technology, and Acacia’s silicon photonic integrated circuit. It is shipping in production volumes today.
