Lumentum Holdings Inc. (“Lumentum”) at this time introduced plans to show an eight-wavelength dense wavelength division multiplexing (DWDM) laser module in an exterior laser small type issue pluggable (ELSFP) at ECOC 2026. This module contains an optical interface designed to satisfy the relevant necessities of the Optical Computing Interconnect Multisource Settlement (OCI MSA). It’s meant for exterior laser supply functions in simultaneous bundle optics (CPO) and close to bundle optics (NPO) architectures. Attendees can view the demonstration at Lumentum stand #2050 in Malaga, Spain.
As AI techniques drive greater bandwidth and port density, CPO and NPO architectures transfer optical engines nearer to change and accelerator packages, lowering {the electrical} distance between SerDes and optics. An exterior laser supply isolates the laser from the very best temperature environments, and the pluggable ELSFP module could be accessed, maintained, and changed independently of the computing and switching packages. DWDM-based architectures can additional improve bandwidth density when bundle edge house and fiber routing are restricted.
The ELSFP module offers eight simultaneous DWDM wavelengths throughout two four-channel bands centered round 1311 nm and 1331 nm. The design targets wavelength accuracy of ±0.2 nm and demonstrates as much as 24 dBm (roughly 250 mW) of optical output energy per wavelength within the fiber. All eight channels function concurrently from a single pluggable module with roughly 12 W of energy consumption. The module makes use of Lumentum’s already production-ready Extremely Excessive Energy (UHP) laser platform in an 8-channel configuration with efficiency tailor-made to relevant OCI MSA necessities.
This demonstration displays the rising want for compact, standards-based laser sources as information heart architectures transfer towards CPO and NPO to satisfy the bandwidth and energy calls for of AI scale-up infrastructure. Lumentum anticipates first availability of DWDM ELSFP modules with OCI MSA optical interfaces within the first half of calendar 12 months 2027.
“CPO and NPO have gotten the defining structure for AI scale-up, and exterior laser sources are a key element of that change,” mentioned Sri Venkat, senior vice chairman and common supervisor of elements at Lumentum. “This demonstration demonstrates our progress in direction of standards-based DWDM ELSFP modules and positions Lumentum to serve clients throughout the CPO/NPO market scale.”
Along with demonstrating the ELSFP module, Lumentum will probably be exhibiting a scale-across networking show that includes merchandise for high-capacity information heart connectivity. The Lumentum OCS R300 optical line change can even be on show on the sales space, highlighting the corporate’s optical switching portfolio for scalable AI infrastructure.
