Acacia Samples New Coherent Bi-Directional Transceiver for Edge and Access Network

2020-10-08    Cfol

MAYNARD, Mass.Oct. 08, 2020 (GLOBE NEWSWIRE) -- Acacia Communications, Inc. (NASDAQ: ACIA), a leading provider of high-speed coherent optical interconnect products, today announced it is sampling new coherent bi-directional pluggable optical module solutions that were designed to transmit and receive data in both directions on a single fiber for 100G and beyond. Offered in a pluggable CFP2-DCO form factor, Acacia’s coherent bi-directional module is designed to deliver an operationally efficient and cost-effective way for telecommunications and cable operators to increase capacity in fiber-limited networks.

In these networks, coherent receivers can efficiently help to eliminate the crosstalk from back reflections when it operates at a different wavelength than its transmitter. Acacia’s coherent bi-directional CFP2-DCO module is purpose-built for these applications.”


In cable networks, particularly Remote PHY and fiber deep applications, providers often run into situations where only a single fiber is available. Historically, these networks have been served by 10G bi-directional optical modules. To meet growing bandwidth demands, a coherent bi-directional solution can provide these networks with an upgrade path to 100G and beyond. When wireless networks are migrating from 4G LTE to 5G, fibers are more often constrained because of a large number of remote nodes and some fibers are utilized by existing services. In these instances, coherent bi-directional modules can alleviate both bandwidth and fiber constraints.

“Cignal AI recognized an opportunity for 100G coherent in the edge and access market back in 2018, and Acacia is the first to aggressively pursue it,” said Scott Wilkinson, Lead Analyst at Cignal AI. “The time is right for network operators, such as cable MSOs, to bring coherent technology to their fiber constrained networks, where Acacia’s bi-directional module can help them increase capacity.”

3D Siliconization Approach
Acacia’s new coherent bi-directional pluggable solutions, with two independent full-tunable laser sources, leverage Acacia’s 3D Siliconization approach, which utilizes high-volume manufacturing processes and benefits from the maturity of Acacia’s silicon photonics technology. Acacia’s coherent point-to-point, DWDM and bi-directional pluggable solutions were designed to meet the form factor, low power consumption and cost requirements that edge and access providers need to scale their networks in the future. These innovations have been made possible through Acacia’s expertise and leadership in silicon photonics and low-power DSPs.

Acacia is announcing the sampling of this solution in advance of SCTE•ISBE Cable-Tec Expo® 2020, which will take place virtually Monday, October 12 - Friday, October 16, 2020. Contact us to learn more about how coherent bi-directional optical modules are a building block to “switch on a pole” access networks.
