Lumentum is highlighting a range of new optical solutions at ECOC 2025 in Copenhagen, with live demonstrations aimed at advancing hyperscale cloud and AI data centers. The company is showcasing innovations across external laser sources, high-capacity pluggables, and ultrawideband tunable lasers.
The demonstrations include the company’s ELSFP modules, which incorporate ultra-high-power 1310 nm lasers for co-packaged optics (CPO) architectures. These external laser source pluggables shift the light source to the system faceplate for improved thermal management, modularity, and serviceability, with sampling expected in Q1 2026. Lumentum is also demonstrating its 1.6T DR8 TRO OSFP transceiver, delivering 8×200 Gbps over 500 meters of single-mode fiber, with lower power consumption than fully retimed alternatives. The module is ramping into volume production.
Additionally, Lumentum is sampling its extended C+L ultrawideband nano-iTLA, covering 12.4 THz across both bands. This narrow-linewidth, fully tunable laser assembly supports metro, long-haul, and subsea networks, with initial units already delivered to key customers. The solution builds on Lumentum’s established external cavity laser technology.
• ELSFP modules with UHP 1310 nm lasers for CPO architectures (sampling Q1 2026)
• 1.6T DR8 TRO OSFP transceiver with 8×200 Gbps over 500m SMF (ramping into production)
• Extended C+L ultrawideband nano-iTLA, >12.4 THz tunability, now sampling
• Targeted at hyperscale AI, cloud, metro, long-haul, and subsea networks
• Live demonstrations at ECOC 2025 booth #C2421
“As AI and Cloud workloads accelerate at an unprecedented pace, the need for faster, more scalable optical solutions has never been greater,” said Rafik Ward, chief strategy and marketing officer at Lumentum. “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.”
🌐 Analysis: Lumentum’s ECOC25 lineup underscores the transition to higher-capacity optics and external laser architectures for AI infrastructure. The ELSFP approach reflects industry momentum toward co-packaged optics, where separating laser sources enhances reliability and serviceability. The 1.6T DR8 TRO OSFP highlights power-efficiency tradeoffs in pluggable transceivers, a critical factor as hyperscalers balance thermal and density limits. Meanwhile, the ultrawideband nano-iTLA addresses scaling in backbone, metro, and subsea networks as bandwidth demand surges. Competitors such as Coherent and II-VI (now part of Coherent) are also advancing in these domains, pointing to intensifying competition across both data center and transport markets.
