Recently, JONHON launched an external light source optical connector tailored for CPO/NPO architectures. Comprising host-side and module-side connectors, this product supports direct blind-mating docking without complex adjustments. It aims to deliver a professional, reliable interconnection solution with high density and low loss for high-speed interconnection scenarios.

Currently, as AI computing clusters rapidly evolve from thousand-card to million-card ultra-large-scale deployments, data centers face exponential pressure in terms of bandwidth, power consumption, and heat dissipation. The mainstream CPO and NPO architectures in the industry widely adopt external light source solutions, independently separating laser light sources into ELSFP to achieve device standardization, independent replacement, and alleviate the heat dissipation load on core chips. As a critical component of the ELSFP fiber interface, the external light source optical connector is the core element ensuring standardized operation and maintenance, as well as the stable transmission of high-power optical signals in this solution.

In terms of product performance, the connector stands out with several highlights: each group integrates 2 MT ferrules, accommodating up to 72 polarization-maintaining fibers per port, significantly enhancing port density within limited panel space and fully meeting the explosive growth in AI bandwidth demands. Paired with low-loss ferrules, the maximum insertion loss is only 0.35dB, ensuring efficient and stable transmission of high-power light source signals. It features a multi-stage precise self-alignment structure, enabling automatic alignment and precise mating without specialized tools, significantly reducing assembly and on-site operational difficulties. Additionally, it complies with the OIF-ELSFP-02.0 industry standard, ensuring interoperability with equipment from mainstream manufacturers. It also supports hot-swapping, allowing direct module replacement during laser failures without system downtime, substantially reducing data center operational costs.

Currently, CPO/NPO technologies have entered the commercial implementation and large-scale deployment phase, widely covering scenarios such as AI data centers, high-speed switches, smart network interface cards, and testing equipment.

JONHON stated that it will continue to delve into core technologies for high-density, low-loss, and highly reliable optical connections, continuously improving product performance, and fully empowering the efficient, low-carbon, and high-quality development of AI computing infrastructure.
