In the wake of ChatGPT’s remarkable debut, the AI landscape has been thrust into a period of exponential growth. A pivotal event occurred in mid-May with the launch of NVIDIA’s DGX H200 for AI, reshaping industry dynamics and igniting an unprecedented surge in demand for 800G optical transceivers. This transformative wave has caught the attention of tech titans like Google, Meta, Microsoft, and others, who are strategically poised to integrate AI into their operations. As AI drives an extensive overhaul of the AI industry chain, Approved Networks, a prominent producer of optical modules, emerges as an integral player in this transformative journey.
In the current landscape, Approved Networks is spearheading the shipment of 800G optical modules, marked by a considerable quantity of multimode modules (800G SR8) and a smaller yet significant number of single-mode modules (800G DR8). Against the backdrop of burgeoning data center traffic demands at the outset of 2023, the industry grapples with the challenge of constrained investment funds. An initial forecast for 3 million units of 800G optical module demand for the year encountered a remarkable twist in June, with demand nearly doubling, and projections anticipate it soaring to tens of millions of units in the forthcoming year.
This chapter of the fiber optic communication industry is one of gradual ascension, as companies progressively bolster their production capacities. The seeds of progress were sown two to three years ago, with numerous enterprises showcasing pioneering 800G demonstration samples. The OFC/ECOC exhibition of 2022 witnessed Approved Networks pivotal role, introducing innovations like single-mode EML chips and multi-mode VCSEL chips for 800G transceiver modules, accompanied by advancements in internal architecture and operational principles.
While this year’s OFC exhibition spotlighted 200G EML technology, the industrialization of 800G optical transceiver modules embarked on its journey with 8x100G modules. This voyage into the future is set to evolve further, envisioning the development of 4x200G and 8x200G 1.6T optical modules.
Within this transformative milieu, multi-mode modules claim a dominant stance, surpassing single-mode modules in quantity. Notably, Approved Networks robust capabilities enable the delivery of several hundred thousand multi-mode 800G optical transceiver modules this year, a testament to their prowess in industrialization. The intricate processes of demand calculation, order placement, and delivery usher in a variety of time points—some estimated for 2023, while others projected for 2024—reflecting diverse perspectives within the industry.
A Surge in Demand
The surge in module demand finds its roots in the interconnection of multiple chips, a phenomenon intimately linked to NVIDIA’s infrastructure. The burgeoning demand for GPUs translates into the requirement for an impressive number of basic transistors to power computation, storage, and control functions. As chip sizes progressively shrink from 10nm to 7nm, 5nm, and beyond, the realm of possibility broadens, accommodating trillions of “super” integrated transistors within a compact area.
Yet, as integration and computational power reach new heights, traditional strategies are no longer sufficient. The limitations of semiconductor chip capabilities call for innovative approaches. Enter chip interconnection, a strategy to amplify computing power by linking multiple chips together. This connection is established using copper or optical fibers, with each avenue offering distinct advantages and challenges.
This marks the juncture where optical modules come into play. An optical module acts as the bridge, converting optical signals into electrical ones. The interconnection challenge, once veering away from optical fibers due to their complexity and cost, has shifted with the increasing application of optical fibers as a data transfer medium, gradually sidelining copper cables. Optical fibers excel in supporting high-capacity, long-distance information transmission. Consequently, integrated circuits are employed for storage, computation, and control functions, necessitating optical modules for seamless optoelectronic conversion.
Amidst this revolution, the current surge in 800G optical transceiver orders isn’t just a reflection of demand for enhanced capacities; it signifies the industry’s arrival at a pivotal stage, albeit with manufacturing capacities still being fine-tuned. The horizon brims with continuous technological exploration and advancements in 1.6T, 3.2T, and 6.4T optical modules, often referred to as optical engines. Silicon photonics, lithium niobate thin films, EML chips, and VCSEL chips are the frontiers where innovation converges, supported by the intricate web of upstream and downstream industry chains.
