Lumentum unveils innovations and demonstrations at OFC
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) has introduced the latest additions to its suite of photonic products at the Optical Fiber Communication Conference & Exposition (OFC 2024) in San Diego, CA, USA (26–28 March). Lumentum says that its innovations are designed to accelerate the speed, efficiency and scalability of cloud, artificial intelligence (AI), and networking applications. The firm is showcasing its products and hosting demonstrations of its photonic technologies in booth #2613 in Hall E, near the OFC registration entrance and in various partner booths.
“We are excited to share with the industry our latest innovations, including our highly differentiated and broad portfolio of photonics products and technology that enable cloud operators and cloud infrastructure providers to further scale AI data centers,” says president & CEO Alan Lowe. “Our showcase at OFC 2024 highlights Lumentum’s commitment to meeting the ever-increasing demands of AI, machine learning (ML), and next-generation communications networks.”
Featured innovations and product demonstrations
- 200G per Lane InP Components: Lumentum is extending its indium phosphide (InP) transceiver component range with its new 200G Lens Integrated Photodiode (LIPD) that supports operation up to 200Gbps per lane, enabling next-generation 800G and 1.6T optical transceivers for large-scale AI and ML applications. Featuring high responsivity and bandwidth, the 200G LIPD is designed for seamless integration with flip-chip bonding techniques and is now available for sampling. The 200G LIPD complements Lumentum’s high-volume, production-ready 200G externally modulated lasers (EMLs), giving optical transceiver manufacturers what are claimed to be best-in-class transmit and receive components for their next-generation 800G and 1.6T solutions.
- Ultra-High Power 400mW 1310nm DFB Laser: Lumentum is introducing an ultra-high-output-power 1310nm DFB laser capable of delivering 400mW of optical power at 50°C. This beta release is designed for co-packaged optics and silicon photonic 800G and 1.6T transceiver applications, offering a solution to reduce the required number of lasers, boosting power efficiency and reliability in large-scale AI and ML infrastructure. Lumentum is demonstrating its ultra-high-power 1310nm DFB laser at its booth.
- Data Center Connectivity Demo including Linear Receiver AOC: Lumentum is demonstrating data-center connectivity scenarios with a 51T switch, a server with a 4x100G NIC, and several of its Cloud Light 800G optical modules operating in a loopback configuration. The performance of a linear receive-only AOC connecting an 800G switch port and the server NIC are being shown in the demonstration.
- 400G QSFP112 DR1.2: Lumentum is also demonstrating its Cloud Light 400G QSFP112 DR1.2 module, which features a 4x100G electrical interface and produces two wavelengths (1290nm and 1310nm), each operating at 200G.
- 400/800ZR+ Modules: Lumentum is demonstrating its 800ZR+ OSFP module operating at 118GBaud 16QAM. Designed to be used in direct router interface applications, performance is being demonstrated over a more than 400km amplified optical link, highlighting the suitability for extended DCI and metro applications. In addition, a high-power 400ZR+ QSFP-DD is being operated over the same link, showing the high performance possible in existing long-haul networks using pluggable modules.
- OIF 400ZR/800ZR Interoperability and CMIS: At OIF's booth #1323, Lumentum is highlighting the interoperability of its 800ZR and 400ZR transceivers with QSFP-DD- and OSFP-equipped switches and routers for IP over DWDM, supporting up to 800Gbps and complying with OIF standards. Additionally, demonstrations of Lumentum’s OpenZR+ and 400ZR QSFP-DD transceivers emphasize the benefits of the CMIS standard for efficient module management and interoperability, enabling precise control over status, optical channels and power across various applications.
- D22 Series Pump Module: This dual-chip 980nm pump laser module offers individual control over each emitter. It integrates Lumentum’s 980nm diode lasers into a compact, hermetically sealed design, delivering exceptional optical power density. The D22 series provides a noise-free, narrowband spectrum and maintains peak performance across various temperatures and current levels. It is suitable for applications demanding superior spectrum control and high-power output, offering up to 2x1100mW.
- 49M Series Multimode Pump Module: Available with 4 or 6 emitters at 980nm, the 49M series delivers powerful output of 40W or 60W while maintaining a compact footprint. Its innovative design simplifies thermal management, supporting both air- and water-cooling systems. This versatility makes the 49M Series suitable for a range of applications, including vacuum, space and terrestrial EDFA pumping.
- Tunable SFP28 ER Module: Designed for industrial temperatures, this high-performance optical transceiver supports 25Gbps DWDM links over distances up to 40km. It offers an upgrade for cable MSOs facing increasing bandwidth demands driven by DOCSIS 4.0 and FTTH deployments. Additionally, it enhances 5G transport network connectivity, leveraging existing C-band fiber infrastructure. Lumentum is demonstrating the capabilities of this new tunable SFP28 ER module at its booth.
