Acacia Communications is sampling new coherent bi-directional pluggable optical modules that were designed to transmit and receive data in both directions on a single fiber for 100G. 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.
Acacia’s coherent bi-directional module is offered in a pluggable CFP2-DCO form factor.
The company said its new products leverage its 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.
“With the addition of this coherent bi-directional solution to our recently announced 100G point-to-point and DWDM coherent solutions, Acacia is now able to offer a portfolio of products to address a wide variety of requirements in the edge and access market,” said Fenghai Liu, Vice President of Product Line Management at Acacia Communications. “In fiber-limited networks, optical waves are transmitted in a single fiber medium from both directions. 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.”
