Building on its success with 400ZR, Acacia’s introduced a portfolio of 800G DSP-based pluggable modules for metro data center interconnect (DCI) upgrades. Acacia’s 800ZR pluggables support QSFP-DD and OSFP form factors fully compliant to OIF 800ZR with transmit power variants.
Acacia’s 800G ZR+ modules are designed to support the recently released OpenROADM specifications that include interoperable PCS transmission capability. The 131Gbaud PCS provides additional OSNR margin at 800G for longer reach suitable for regional DCI applications, linking multiple fiber spans and in-line amplification between data centers. Acacia 800G ZR+ pluggables support QSFP-DD and OSFP form factors with >1dBm transmit output power.
Acacia is also introducing a 400G QSFP-DD module for ultra long-haul applications. It offers 400G QPSK and PCS with various baud rates to fit into different ROADM optical line systems. It is capable of >1dBm transmit power and high transmit OSNR over the entire C-band thanks to the integrated tunable optical filter for amplified spontaneous emission reduction.
Both the 800G pluggable portfolio and 400G ultra long haul pluggable are powered by Delphi, Acacia’s 9th generation Digital Signal Processor (DSP) ASIC.
Acacia notes that its 400G MSA coherent pluggable portfolio, based on its Greylock DSP, has now shipped more than 250,000 ports, including more than 10,000 Bright 400ZR+ ports.
The Delphi DSP-based pluggable modules are planned to be available beginning in Q2 CY2024.
