Acacia AC1200-SC2

Acacia has many reasons to be excited about this year’s European Conference on Optical Communications (ECOC) and one of the top ones is demonstrating our new AC1200-SC2 (SC ‘squared’) coherent module, the first single-chip coherent module to deliver 1.2 Terabit (1.2T) on a single-channel. Not only did we announce the details around the AC1200-SC2 today, but we also had four customers participate in our press release by providing supporting quotes. Thank you to ADVA, Cisco, ECI Telecom, and ZTE for your continued support of our product innovations. Everything we develop is to make you and our other customers successful, and we’re proud to once again have the opportunity to help you solve your greatest optical networking challenges.


Powered by Acacia’s 1.2T Pico DSP chip, the AC1200-SC2 was designed to enable network operators to support today’s 100GbE clients, as well as emerging 400GbE clients, across key network segments such as DCI edge, metro, long-haul and submarine in an efficient, scalable, and cost-effective manner. The module’s high-performance and flexibility make the AC1200-SC2 module ideally suited for multi-haul applications ranging from high- capacity 1.2T DCI edge to the most challenging terrestrial and submarine networks that require 400G channels and QPSK modulation.


Optimize your Network

The AC1200-SC2 leverages Acacia’s 3D shaping technology designed to optimize fiber capacity and reach by filling gaps in margin and spectrum. Fine-tune adjustment of the modulation order and baud rate

provides network operators with the ability to adapt the transmission characteristics to meet the requirements of both greenfield and brownfield deployments. Capable of adapting to any channel spacing up to 150 GHz, the AC1200-SC2 provides network operators with a straightforward channel plan roadmap.


The single-chip, single-channel AC1200-SC2 supports 3 x 400G transmission using 64QAM modulation for DCI edge applications, as well as 1 x 400G transmission using QPSK modulation for long-haul and submarine applications. This application flexibility facilitates network savings by enabling common hardware to address multiple deployment scenarios, including 100GbE/400GbE, as well as reducing the need for costly regeneration nodes for long-haul and ultra-long-haul links.


The software intelligent AC1200-SC2 coherent module supports 1.2T in a footprint that is 40% less than the size of 5” x 7” modules supporting transmission speeds of 400G today.
