Quantifi Photonics Introduces ELSFP 1000 Series

On January 20, 2026, at Photonics West 2026, Quantifi Photonics, a frontrunner in photonic IC testing solutions, announced the launch of its ELSFP 1000 Series. This groundbreaking series is the first PXI-compatible solution developed in accordance with the External Laser Small Form-Factor Pluggable (ELSFP) standards. It aims to enhance testing capabilities for Co-Packaged Optics (CPO), Photonic Integrated Circuits (PICs), and optical modules by offering a multi-channel, high-power continuous-wave optical output.

The Innovation Behind ELSFP 1000 Series

The ELSFP 1000 Series is designed specifically for high-density test setups, which is crucial in environments that demand rigorous validation and manufacturing standards. As Kees Propstra, VP of Product Marketing at Quantifi Photonics, stated, "As demand for reliable, high-channel-count and high-power optical sources grows, the ELSFP 1000 Series meets these needs by blending the ELSFP standard with the robust PXI framework. This combination offers unparalleled density and flexibility for multi-channel test setups."

Key Features

• - Optical Power: Each ELSFP 1000 unit can provide up to 25 dBm, with various models available supporting 23 dBm or 20 dBm optical output. This ensures that development teams can scale their test systems, effectively handling dozens to hundreds of channels without compromising on quality.
• - Integrated MPO Connectors: The series features 8 channels of optical power equipped with MPO connectors, simplifying fan-out configurations and high-density connections.
• - Wavelength Specifications: Operating at a wavelength of 1311 nm, the system uses PM1300 fiber outputs, ensuring polarization stability, which is essential for high-precision measurements.
• - Compact Form Factor: The PXIe (2-slot) form-factor ensures a compact design suitable for dense and rack-friendly testing systems.
• - Future-Proof Technology: The ELSFP 1000 is compliant with the ELSFP standards and will support future modules with Power Class 6 capability, reaching up to 30 W. This ensures that the technology remains relevant as industry needs evolve.

Significance of ELSFP in Manufacturing

The ELSFP standard plays a vital role in the realm of photonic IC-based technologies by providing a reliable source of continuous-wave optical power externally. The benefits of this standard include the ability to closely replicate optical power distribution found in current deployments, which accelerates the development and validation processes crucial for production testing.

The ELSFP 1000 Series is not just another launch for Quantifi Photonics; it represents a significant step forward in advancing the capabilities of CPO and PIC manufacturing. As reliance on optical networks grows, integrating such innovative solutions is pivotal for achieving high-volume manufacturing objectives.
