XT1600 High-Density Linear Optical Engine

XT1600 High-Density Linear Optical Engine

The 16 x 112 Gbps optical engine delivers 16 independently routable full-duplex 100G optical links on a 15mm x 15mm footprint.  The XT1600 is E2E optimized for industry-leading density and performance in direct-drive (aka “linear”) applications. It is packaged for the customers’ convenience from tight-pitch LGA on the bottom to thermal interface on top to connectorized fiber pigtails for both data signals and external laser sources.  

On-board equalization generates exceptional signal quality enabling direct-drive (linear) operation across up to 20 dB of electrical trace loss at each end of the link, alleviating break-out routing challenges in high-performance systems. By eliminating the dedicated optical DSP to save power and cost, it also provides more than 200 ns of latency savings compared to conventional retimed optics.

It supports a wide range of data rates from 25G NRZ to 100G PAM4, supporting a variety of protocols including 100GbE, 400G-DR4, 800G-DR8, PCIe 5.0 and PCIe 6.0. Its high density makes it suitable for co-packaged optics, near-package optics and inside modules.

Nitro 200G Linear Redriver front and back

Nitro 200G Linear Redriver

Nitro leverages the linear high-speed analog electronics technology developed by Nubis for its optical products to enable extremely low power, low latency and breakthrough reach for active copper interconnect solutions. with extended reach that allow the continued scaling of AI systems within and beyond a server rack even at 212 Gbps speeds. The breakthrough E2E approach achieves reach extensions to 4m of twin-ax, beyond the capabilities of legacy analog equalizers that need to be tuned per channel.

Available in either 4 or 8-lane versions, the chips in advanced fan-out panel-level packaging are ready for customer integration into active copper cables.

Optical Engine Technology

The Nubis optical engine is uniquely designed to minimize electrical and optical loss and provide the best possible signal integrity. This minimizes power consumption that would otherwise be required to clean up or even retransmit the very high-speed data signals. With 16 full-duplex bidirectional channels of 100G PAM4 today, it is designed to match the density and lane speeds of today’s most advanced Serdes at 100G PAM4 per lane and is ready for 200G PAM4 per lane tomorrow.

Silicon Photonics

Nubis achieves the industry’s highest-density integration of 1.6 Tbps full-duplex in a single silicon photonics PIC with Nubis’ own modulators, photo detectors, and other advanced elements. The combination of proprietary design with fabrication in a high-volume commercial foundry maximizes both performance and reliability.

High-Speed Electronics

Our own optical drivers and TIAs are purpose- built for use with our PICs and include advanced equalization to mitigate imperfections in both the optical and electrical channels. Co-design of PIC and ICs is optimized through deep understanding of the entire link through the use of NubisSim.

2D Fiber Array

A patented fiber coupling method uniquely achieves pitch-matching to modern SerDes chip beachfront density for all signal and external laser source fibers. This approach solves the need for high radix breakout for individual fibers while keeping high density in the engine package.

Advanced Packaging

3D wafer-scale hybrid integration combines the PIC and high-speed electronics with minimized trace lengths for best signal integrity. Together, the high-speed electronics and PIC achieve optimum signal integrity to support record-breaking direct-drive (linear) operation.

NubisSim™

A robust simulation environment that accurately models the electro-optical data path from the transmitting host SerDes through packaging and optics all the way to the receiving host SerDes. This next-gen design tool allows Nubis and its customers to co-design the densest, lowest-power and highest-speed optical interconnects
