CIM8 Technology Differentiators

Second Generation 3D-Shaping

The CIM 8 powered by the Jannu DSP utilizes Second Generation 3D Shaping technology optimizes capacity and reach for network operators up to 1.2T and 140Gbaud with 20% higher spectral efficiency over the previous generation. 2nd Generation 3D Shaping provides state-of-the-art transmission shaping capabilities using enhanced probability constellation shaping (PCS) algorithms to provide continuous modulation, baud rate, and spectral efficiency adjustment.

Adaptive Baud Rate

A feature first introduced in Acacia’s Pico DSP and AC1200 module, Adaptive Baud Rate has been widely embraced by network operators. The CIM 8 Adaptive Baud Rate feature provides customers with continuous baud rate adjustment up to 140Gbaud to optimize utilization of available spectrum in a single-span or in cascaded ROADM paths. With this continuous baud rate tuning capability, the CIM 8 also offers maximum capacity over any channel plan.

Other Key Features

The CIM 8 powered by Jannu includes Acacia’s advanced line-rate power-efficient processing algorithms to efficiently overcome fiber transmission impairments over greenfield or brownfield fiber infrastructures by compensating linear and non-linear impairments, as well as providing state-of-polarization (SOP) tracking twice as fast as the previous generation. In addition, the CIM 8 powered by Jannu leverages Acacia’s new innovative soft-decision error correction (SD-FEC) to further enhance performance.

Five In-house Technology Capabilities Deliver Multiple Advantages

Unlike competing solutions, Acacia has the key capabilities in-house for building superior optical interconnects. This comprehensive technology portfolio improves efficiencies between layers and enables a high level of multi-disciplinary collaboration across all stages of the product development lifecycle. Working together, the five key technology capabilities deliver rapid innovation, superior performance, higher yield, better integration, and lower cost.

Our Journey

Innovation is in our DNA and at the core of what we do every day. Founded in 2009, our founders recognized a market opportunity leveraging silicon photonics and, as a result, built a new kind of technology company.

Cloud / Data Center Interconnect

Large cloud infrastructure operators and internet content providers have increasingly been building global private networks using leased or owned dark fiber. These networks require high speed optical solutions to address the growing inter-datacenter east-west traffic increasing at a faster rate than north-south traffic between users and the data centers. Contributing to east-west traffic growth is synchronization and load balancing to maximize the utilization of available data center resources. East-west traffic is expected to grow with rising artificial intelligence/machine learning (AI/ML) applications.

Enterprises transitioning from operating their own data center to cloud-based services is driving host data center growth. The massive bandwidth interconnect requirements for these mega-data centers are driving demand for both performance-optimized and pluggable power-optimized coherent optical solutions for these links, placing the highest value on cost per bit.

Metro Carrier

Metro carrier optical networks interconnect a wide range of traffic from central offices and data centers within a metropolitan area. These networks are optimized for small physical footprints and low power but must deliver ever-more bandwidth to meet customer needs. These complex mesh networks typically cover ranges from 80km to 1,500km and may include up to 24 reconfigurable optical add-drop mux (ROADM) nodes.

The introduction of Acacia’s low power, pluggable coherent CFP module in 2014 made long-haul-centric coherent technology much more appealing in metro applications. Fiber infrastructure impairments due to legacy fiber, wavelength selective switch (WSS) based ROADMs, polarization mode dispersion (PMD), polarization dependent loss (PDL), and reduced channel passbands could be even more severe in the metro compared to long-haul networks. Coherent technology can overcome all these impairments.

Enabling Products

Long Haul

Long haul terrestrial networks link major population centers within continents, spanning distances from 1,500 km to more than 2,500 km. While traditionally used by service providers, cloud network operators are also using long haul networks to mirror data between servers in geographically diverse data center locations.

Long haul networks put a high value on performance. The ability to communicate over longer distances results in significant cost savings to the overall network due to the reduction of regeneration stages, where signals are converted from the optical domain to electrical and back. The latest generations of coherent technology can optimize for capacity and reach with great flexibility and performance, while also including impairment mitigation features that are key for robust long haul networks. In addition, recent advancements in high baud-rate coherent optics have enabled long haul applications to be addressed using pluggable coherent modules.

Our DSPs are at the heart of our module products. They enable the optical performance and low power that have become synonymous with Acacia throughout the optical transport industry. For some customers, standard module form factors do not align well with the size or power limitations of their application. These customers buy the DSP directly from Acacia and integrate them directly on their linecards using an Acacia-provided reference design.

Silicon PICs

Acacia is a pioneer in the introduction of silicon-based PICs for coherent optical communications—the highly integrated Silicon Photonics single-chip PICs are low power and ultra-compact. Coupled with Acacia’s DSP, the combination provides a leading coherent solution in low power and size. Acacia’s PIC is optimized for high yield, enabling high volume manufacturing. Leveraging mature CMOS processes, our Silicon Photonic PICs can eliminate.

Disruptive Innovation

Acacia has harnessed the power of digital signal processing and silicon photonics and introduced innovations such as 3D Siliconization. This has enabled us to take bulky and complex technology and accelerate its evolution into more compact, easier-to-use, and easier-to-manufacture solutions using advancements in integrated silicon design and packaging, DSP technology, high-speed RF design, and software implementations.
