The company introduces a family of pluggable optical modules spanning 100G to 400G and beyond for Hyperscale Data Centers, Cloud, Enterprise, and Metro network operators across the United States. Hyper Photonix’ 400G QSFP-DD DR4 module is capable of up to 2km transmission distance.

Jabil Inc. announced that its photonics business unit is expanding its design, manufacturing, and testing capabilities, culminating in the launch of a new active optical cable (AOC) family. Its first 800G AOC product will be available during the second half of 2023; development is underway on 400G AOC products to extend the AOC product line while accommodating a wide range of applications. Also at OFC’23, Jabil showcased its advanced photonics solutions.

Keysight attended OFC 2023 to share how its design, development, validation, and emulation expertise enables R&D professionals to achieve data transmission speeds of 800G, 1.6T, or higher for their optical components and modules. Keysight presented demonstrations in integrated photonics, advanced 1.6T research, 160 gigabaud and beyond research, optical module interoperability, and an 800G/1.6T manufacturing test; using products such as the N4372E Lightwave Component Analyzer, the 110 GHz UXR1102A Infiniium UXR-Series Oscilloscope (in combination with the 120GHz N1046A Electrical Remote Sampling Head Module and the N1000A Digital Communications Analyzer), and the M8050A High-Performance BERT.

Lumentum Holdings Inc. (“Lumentum”) highlighted its portfolio of full band optical tunable transceivers in a live product demonstration, including 10G optical transport network (OTN) SFP+, 25G T-SFP28, and 100G coherent CFP2-DCO bi-directional (BiDi) transceiver modules. The 25G T-SFP28 product incorporates MSA-compliant SmartTunable technology to simplify field deployment tasks by adopting self-tuning algorithms. Lumentum also introduced the industry’s first 100G CFP2-DCO BiDi and 10G OTN modules to address capacity and reach challenges within DAA rollouts. The 100G CFP2-DCO BiDi is a unique product that allows capacity increases that utilize only a single fiber.
