Acacia’s Bright 400ZR+ QSFP-DD pluggable module is being deployed and trialed in a wide range of networks as operators Arelion, CENIC, Sipartech, and Vodafone Turkey take advantage of their compact size, low power consumption, interoperability, and ability to be deployed directly in routers and switches for significant cost savings.

Arelion Achieves 64% CAPEX and 76% OPEX Savings Enabled by Bright 400ZR+ Deployment

In August 2023, Arelion announced that it has taken another landmark step in converging its IP and optical layers as the first global network to deploy 400G QSFP-DD ZR+ Bright coherent optical modules in its production #1 ranked IP backbone. This first regional reach deployment spans 675 kilometers between Stockholm and Copenhagen over third-party Optical Open Line System (O-OLS). According to Arelion, the streamlined architecture eliminates the need for excessive hardware, thereby reducing potential points of failure. As a result, it achieves 64% CAPEX and 76% OPEX savings. This contributes to a significantly more cost-efficient network with fewer interfaces to control and maintain.

Highlighting the benefits of these modules, Arelion’s Mattias Fridström shares his insights in this video from testing the technology to how they can potentially transform network infrastructures.

Dariusz Solowiej, VP Network Technology & Customer Operations at Arelion added, “With constantly rising demand for our IP services and increasing traffic across the Internet, Arelion is constantly looking to deploy the latest technology. The deployment of 400G QSFP-DD Bright Optical Modules will ensure cost-effective, high-performance connectivity for our customers and help us grow our network in scale as we continue to connect the world. In addition, the coherent pluggable modules also help us achieve our sustainability goals through improved energy efficiency and redeploying redundant hardware assets.”

CENIC Validates Coherent Pluggable Optics for Big Data Applications
Using Bright QSFP-DD coherent optics, the Corporation for Education Network Initiatives in California (CENIC) turned up a 300 Gbps optical service over CENIC’s production line system between Los Angeles and Sunnyvale and confirmed the error-free performance of the service with a comfortable operating margin.

According to CENIC, the new-generation coherent pluggables integrate an amplifier, making it possible to transmit from the optic at power levels that match those of typical transponder line cards. As a result, external amplification is no longer needed to boost the power level transmitted from the optic before it reaches the optical line system.  As explained by Sana Bellamine, CENIC’s Director of Regional and International Infrastructure, “The elimination of the external amplification requirement is an important step toward simplifying the provisioning of optical services and facilitates the adoption of coherent pluggables over our production line system.”

Bright 400ZR+ QSFP-DD Modules Expands Applications by Enabling Longer Reach Applications
With an optical transmit power at least 10X greater than 400ZR, Bright QSFP-DD modules enable network operators to expand applications that can be addressed by 400G coherent pluggables in router-based optical deployments to include brownfield and greenfield metro/regional networks with reconfigurable optical add-drop multiplexer (ROADM) nodes.
