[Copenhagen, Denmark, ECOC2025 Venue] At the turn of September and October, this fairy-tale capital city has gathered the bright stars of the global optical communication industry. At the 51st European Conference on Optical Communication (ECOC2025), OTRANS, with the theme of "Intelligent and Simplified Architecture, Empowering Computing Power", grandly showcased the core optical connectivity solution for the next-generation data centers - the SJ Series high-density product family, becoming one of the most eye-catching highlights at the exhibition.
Undoubtedly, the upgrade of optical modules was the core topic of this year's ECOC. We observed that mainstream manufacturers, such as Broadcom, Cisco, NVIDIA, as well as numerous optical module companies including Coherent, Innolight, and Accelink, have fully focused their exhibition highlights on the mature solutions and early deployment of 800G DR8/2xFR4/VR8 and 1.6T pluggable optical modules.
Parallel optics become the absolute mainstream: Whether it is the 800G-SR8 for short-reach multimode or the 800G-DR8 for single-mode long-reach, their cores all rely on 16-fiber/24-fiber MPO optical fiber links. This means that the basic cabling of data centers must fully evolve from the traditional duplex LC to the higher-fiber-count MPO system.
Bandwidth acceleration and architecture innovation: The explosive growth of AI and HPC is driving the iteration of data center networks from 400G Spine-Leaf to 800G and even higher-bandwidth architectures. The interconnection bandwidth demand between servers and switches has jumped from the mainstream 25G/100G to 50G/200G/400G.
These trends clearly point to a conclusion: a flexible, high-density, and future-oriented optical fiber cabling infrastructure is the cornerstone for supporting the performance release of optical modules and ensuring the stable upgrade of networks.
Based on a profound insight into industry trends, the SJ Series solutions exhibited by OTRANS this time directly address the current pain points of data center interconnection and provide an optimal solution for high-speed optical connectivity between servers, switches, and storage systems.
1. Core Cornerstone: SJ Series 192-Fiber/1U Ultra-High-Density Patch Panel
In modern data centers where space equals cost, the SJ Series fiber optic distribution frame achieves an amazing ultimate density of 192 optical fibers within 1U space. Its modular and slide-rail design not only facilitates installation and maintenance but also provides the core computer room with unparalleled port density and flexible expansion capabilities, reserving sufficient space for bandwidth growth in the next few years.
2. Neural Hub: Full Range of MPO-LC Conversion Modules
OTRANS provides a complete range of 8-fiber, 12-fiber, 16-fiber, and 24-fiber MPO-LC conversion modules, perfectly adapting to the needs of optical modules of different generations:
8-fiber modules: Continuously serve the mature Breakout scenarios from 40G-SR4 to 4x10G and from 100G-SR4 to 4x25G, making them a cost-effective choice for the server access layer.
12-fiber/16-fiber modules: Fully support mainstream 100G-SR4/PSM4 and 400G-SR4.2/DR4 applications. In particular, our 16-fiber modules seamlessly connect to the latest 800G-SR8/DR8 optical modules, and are indispensable connection components for building 800G systems.
24-fiber modules: Proactively prepare for parallel optical applications of 1.6T and higher rates.
3. Exquisite Details: Boot-Pull Type High-Density LC/MPO Connectors
Facing the operational challenges brought by high-density cabling, our innovative boot-pull LC fiber connectors perfectly match the SJ Series ultra-high-density LC adapters and module applications. This design allows engineers to easily and safely plug and unplug LC connectors even in narrow spaces, greatly improving operation and maintenance efficiency and reducing the risk of optical fiber damage. At the same time, the boot-pull MPO connectors, combined with our high-performance 12-fiber/16-fiber MPO adapters, ensure extremely low insertion loss and ultra-high reliability for each backbone connection in high-density cabling environments.
Through this complete set of solutions, OTRANS can help customers easily achieve seamless upgrading from 40G to 800G, maximize the protection of existing investments, and pave the way for future technological evolution.
During the three-day exhibition, data center operators and system integrators from Germany, the United Kingdom, France, Spain, and various Nordic countries showed strong interest in our SJ Series.
In-depth technical exchanges: Many customers consulted on-site about specific deployment cases of the 16-fiber MPO system in 800G scenarios and the compatibility details of single-mode/multimode modules. Our sales engineer team conducted detailed and in-depth technical discussions with the customers.
Quality wins praise: Visitors highly praised the forward-looking and original design, exquisite craftsmanship, and reliable and durable overall connection solutions of our products. "OTRANS' comprehensive design and product manufacturing capabilities are exactly what we are looking for in an ideal high-quality partner," commented a data center product director from the United Kingdom.
Frequent cooperation intentions: Through this exhibition, we have obtained dozens of valid cooperation intentions and sample testing requests. What is even more exciting is that some top-tier customers also brought us valuable "creative proposals" and conducted constructive discussions on the intelligent management of next-generation products (such as the integration of NFC tag identification) and the application of environmentally friendly materials, injecting new inspiration into our future product research and development.
ECOC2025 is coming to an end, but OTRANS' journey of leading innovation in high-density optical connectivity will never stop. This trip to Copenhagen not only allowed us to show the world the strength of "Made in China" (in terms of intelligent manufacturing) but also clearly saw the urgent demand of the global market for high-performance and high-reliability cabling solutions.
OTRANS will always adhere to the concept of "creating more valuable connectivity solutions" and work hand in hand with global partners to jointly light up every beam of light leading to the digital future.
