Lumentum giving live technology and product demos at ECOC
On stand #C2421 at the European Conference on Optical Communication (ECOC 2025) at the Bella Center in Copenhagen, Denmark (29 September–1 October), Lumentum Holdings Inc of San Jose, CA, USA (which designs and makes optical and photonic products for optical networks and lasers for industrial and consumer markets) is giving several live technology and product demonstrations, reinforcing its focus on enabling AI-driven data centers and the world’s largest communications networks.
Live demonstrations during the exhibition include the following:
ELSFP transceivers for CPO architectures
Lumentum is showcasing its development of external laser source (ELS) modules in the ELSFP pluggable form factor, designed to advance co-packaged optics (CPO) architectures in high-bandwidth environments such as hyperscale data centers and AI clusters. The demonstration highlights pluggable modules incorporating Lumentum’s ultra-high-power (UHP) 1310nm lasers, enabling next-generation switches and AI processors with integrated optical connectivity. By separating the laser source from the optical engine and placing it at the system faceplate, these modules improve thermal management and reliability, while their design enhances serviceability and modularity.
The ELSFP form factor provides higher system density, lower thermal loads, and improved lifetime performance, all while maintaining standards compliance. This product is expected to be sampling in first-quarter 2026.
1.6T DR8 TRO OSFP transceiver for cloud and AI applications
Lumentum is also demonstrating its 1.6T DR8 TRO OSFP pluggable transceiver module, which provides 8x200Gbps data connectivity over 500m of single-mode fiber optics targeting hyperscale cloud and AI applications. Its TRO (‘Transmit-Retimed Optical’) design offers significantly lower power dissipation compared with a fully retimed optical (FRO) transceiver module. The product leverages internal Lumentum manufacturing and components and is currently ramping into volume production.
Extended C+L ultrawideband Nano-iTLA now sampling
In addition, Lumentum is sampling its ultrawideband narrow-linewidth InP nano-iTLA. This new laser assembly provides full tunability across more than 12.4THz, covering both the extended C- and L-bands, making it suited to supporting the increased bandwidth demand driven by AI data centers, data-center interconnects (DCI), metro, and long-haul networks. Building on Lumentum’s proven external cavity laser (ECL) technology, the ultrawideband nano-iTLA is delivered in the same compact form factor as existing solutions, with a single wideband tunable laser. It offers what is claimed to be best-in-class narrow-linewidth performance, enabling superior signal integrity and system reach. Initial units have been delivered to key customers for evaluation in next-generation optical networks.
“As AI and cloud workloads accelerate at an unprecedented pace, the need for faster, more scalable optical solutions has never been greater,” says Rafik Ward, chief strategy & marketing officer. “With our latest innovations, Lumentum is shaping the future of network infrastructure and empowering customers to build the data centers and AI networks of tomorrow.”
