Lumentum demos technologies and products for scale-out, scale-up and scale-across applications
In booth #1439 at the Optical Fiber Communications Conference and Exhibition (OFC 2026) at the Los Angeles Convention Center (17–19 March), Lumentum Holdings Inc of San Jose, CA, USA (which designs and makes photonics products for optical networks and lasers for industrial and consumer markets) is showcasing technology and demonstrating products designed to meet the accelerating demands of next-generation AI and data-center infrastructure.
Multiple demonstrations for scale-out and scale-up networking applications being showcased include:
- 1.6T DR4 OSFP module with 400G differential EMLs
The 1.6T DR4 OSFP pluggable transceiver prototype uses four Lumentum 400G differential EML lasers, as a stepping-stone to a future 3.2T module. The module provides 4x400Gbps data connectivity over single-mode fiber optics and 8x200Gbps electrical interface on the host side. Its 4x400Gbps design leverages Lumentum’s advanced components, packaging and high-volume manufacturing expertise, targeting next-generation hyperscale AI data-center applications.
- 800mW Super-High-Power (SHP) laser
Lumentum is highlighting its SHP laser following the launch of its 400mW Ultra-High-Power (UHP) laser in 2025. The 1310nm device delivers more than 1.0W optical power at 25°C and over 800mW at 50°C, with <100kHz linewidth and >40dB SMSR, enabling high-power, high-performance light sources for co-packaged optics (CPO) and other silicon photonics architectures in both direct-detect and coherent-lite applications.
- 16-channel DWDM UHP laser
The firm is featuring a 16-channel DWDM laser source, illustrating Lumentum’s readiness to support next-generation CPO architectures that require high bandwidth densities while reducing overall fiber count around a host switch or compute ASIC. The DWDM UHP lasers are demonstrated using two ELSFP modules producing 16 simultaneous channels across a 200GHz grid centered at 1310nm, delivering optical power of about 24dBm per channel into fiber. The wavelength grid is compliant with the CW-WDM MSA.
Additional demonstrations featured for scale-across and telco applications include:
- Multi-rail Coherent Optical Channel Monitor (C-OCM)
This demonstration showcases three new products: - Twin C+L-band C-OCM;
- C+L-band integrated tunable laser assembly (iTLA); and
- Quad integrated C+L-band 3x33 wavelength-selective switch (WSS) module (proof-of-concept design).
The C-OCM integrates two C-band and two L-band channels providing 4x the density of currently available modules on the market. These four channels can be scanned concurrently delivering instrument-grade resolution for enhanced diagnostics and performance monitoring capabilities.
The C+L-band iTLA significantly enhances the performance of the nano-iTLA. The tunable operating frequency range is expanded by greater than 200% compared to traditional iTLA products, enabling continuous tuning coverage over 12.4THz in both C-band and L-band optical windows.
The Quad integrated C+L-band 3x33 WSS module is targeted for multi-rail terminal WSS applications and is a proof-of-concept design that can be rapidly brought into production.
- Multi-rail Dynamic Gain Equalizer (DGE) with integrated OCM
The multi-rail DGE with integrated OCMs offers 4x the density of currently available solutions. DGEs are necessary in long-haul DCI scale-across networks to optimize spectral performance over cascaded in-line amplification nodes. The production-released version of this product will combine eight equalizers with 16 channel monitors in an ultra-compact form factor to support equalization and input/output channel monitoring for two fiber pairs (or rails) carrying C- and L-band data.
“From 400G-per-lane pluggable modules to ultra-high-power laser sources and advanced coherent monitoring, our portfolio is designed to enable the scale, speed and efficiency required by next-generation AI and cloud data-center infrastructure,” says Rafik Ward, senior VP, chief strategy officer & chief marketing officer.
