HyperLight Introduces 145 GHz Reference Modulators to Enable 448Gbps per Lane Datacom and 260GBaud Telecom Development

Why It Matters

By surpassing the 100 GHz barrier in a packaged form, the modulator enables higher‑capacity data‑center interconnects and next‑generation telecom links while lowering integration risk for equipment manufacturers.

Key Takeaways

• 145 GHz modulator supports 448 Gbps per lane IMDD
• Enables 260 GBaud coherent telecom links
• Packaged with 0.8 mm RF connector for high‑frequency integration
• Available in O, C, L bands; 1 µm pre‑order
• Built on Telcordia‑qualified TFLN Chiplet platform

Pulse Analysis

The relentless growth of AI workloads and cloud services is forcing data‑center architects to seek optical links that can handle ever‑higher symbol rates. Traditional 100 GHz‑class modulators are becoming a bottleneck as operators look to aggregate multiple terabits per second across short‑reach interconnects. A new class of ultra‑wide‑band devices is therefore essential to sustain the scaling of Ethernet standards and to support emerging coherent‑detection schemes in metro and long‑haul networks.

HyperLight’s 145 GHz packaged intensity modulator leverages its proprietary TFLN Chiplet™ technology, which integrates thin‑film lithium‑niobate waveguides with silicon photonics for superior electro‑optic efficiency. The package incorporates a 0.8 mm RF connector, polarization‑maintaining fiber, and a high extinction ratio, delivering reliable performance up to 145 GHz without the need for custom laboratory setups. This combination of bandwidth, power handling, and turnkey packaging reduces the engineering overhead for OEMs and accelerates time‑to‑market for products targeting 448 Gbps per‑lane IMDD or 260 GBaud coherent channels.

The introduction of a commercially available 145 GHz modulator reshapes the competitive landscape, pressuring incumbents to accelerate their own high‑bandwidth roadmaps. Operators can now design link architectures that consolidate fewer wavelengths while achieving higher data rates, translating into lower cost per bit and simplified fiber management. As standards bodies draft next‑generation specifications, HyperLight’s offering positions it as a key enabler for the forthcoming era of terabit‑scale optical networking, potentially influencing both datacenter and telecom equipment roadmaps.
