Soft Decision Forward Error Correction Coherent Digital Signal Processor (SD-FEC Coherent-DSP) Global Market Report 2025

The soft decision forward error correction coherent digital signal processor (SD-FEC coherent-DSP) market size has grown exponentially in recent years. It will grow from $1.21 billion in 2024 to $1.46 billion in 2025 at a compound annual growth rate (CAGR) of 20.4%. The growth during the historic period is attributed to rising demand for bandwidth, increased adoption of coherent detection, enhanced data center connectivity, greater cloud computing usage, and expanded deployment of fiber networks.

The soft decision forward error correction coherent digital signal processor (SD-FEC coherent-DSP) market size is expected to see exponential growth in the next few years. It will grow to $3.03 billion in 2029 at a compound annual growth rate (CAGR) of 20.1%. The growth in the forecast period is driven by greater adoption of 5G technology, increased investments in optical infrastructure, growing demand for high-capacity networks, expansion of AI and machine learning applications, and wider integration of software-defined networking. Key trends in the forecast period include advancements in silicon photonics, integration of machine learning algorithms, innovations in low-power DSP chips, development of coherent pluggable modules, and progress in multi-level modulation formats.

The rising demand for high-speed connectivity is expected to drive the growth of the soft decision forward error correction coherent digital signal processor (SD-FEC coherent-DSP) market. High-speed connectivity refers to data transmission systems capable of delivering rapid and reliable communication across networks. This demand is increasing primarily due to the exponential growth of digital data traffic from cloud computing and video streaming. SD-FEC coherent-DSP supports this demand by improving error correction in optical signals, allowing longer transmission distances, higher data rates, enhanced signal integrity, and reduced bit error rates. For example, in December 2024, according to the Office of Communications (Ofcom), a UK-based communications regulator, 69% of UK households (approximately 20.7 million homes) were equipped with full-fiber broadband, up from 57% (17.1 million homes) in September 2023. The rising demand for high-speed connectivity is therefore propelling the growth of the SD-FEC coherent-DSP market.

Major companies in the SD-FEC coherent-DSP market are developing high-performance coherent digital signal processor (DSP) merchant ICs to increase data throughput, extend transmission reach, reduce power consumption, and enable cost-efficient scaling of high-speed optical networks. These merchant ICs are commercially available integrated circuits that employ advanced digital signal processing to support high-speed, long-reach, and energy-efficient coherent optical communication in data center and telecom networks. For instance, in March 2023, Credo Technology Group Holding Ltd., a US-based fabless semiconductor company, partnered with EFFECT Photonics B.V., a Netherlands-based photonics company, to co-develop coherent DSP merchant ICs. The collaboration combines EFFECT Photonics’ coherent DSP and forward error correction (FEC) technology with Credo’s high-speed SerDes, I/Os, ADCs, and DACs. Credo handles manufacturing, sales, and customer support for these low-power, high-performance solutions, which target 100G ZR and 100G ZR+ applications in QSFP28 modules, supporting service providers, 5G telecom, and fixed-access operators transitioning from 10G to 100G networks.

In March 2022, Effect Photonics, a Netherlands-based provider of integrated optical communication products, acquired Viasat Inc.’s coherent optical DSP and FEC business for an undisclosed amount. This acquisition granted Effect Photonics full ownership of the coherent technology stack, including DSP and SD-FEC capabilities, enabling the company to offer optimized, cost-effective, and energy-efficient coherent communication solutions. The move also expanded Effect Photonics’ product portfolio and strengthened its position as an independent vendor in the coherent optical market. Viasat Inc. is a US-based provider of high-speed satellite broadband services and secure networking systems for military and commercial markets.

The regions covered in this report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East and Africa.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
