JONHON Launches External Light Source Optical Connector to Support Next-Generation AI Supercomputing Optical Interconnection Upgrades

As AI computing clusters rapidly scale from thousand-card to million-card ultra-large computing power configurations, data centers are facing exponential increases in bandwidth, power consumption, and thermal dissipation challenges. Currently, mainstream industry architectures such as CPO (Co-Packaged Optics) and NPO (Near-Packaged Optics) widely adopt external light source solutions: the laser light source is decoupled from the chip and integrated into an ELSFP (External Laser Small Form Factor Pluggable) module. This approach not only enables standardization of optical source devices and supports independent replacement, but also significantly alleviates the thermal load on core chips. As the fiber optic interface for ELSFP, the external light source optical connector is a critical component that ensures the standardization, pluggable maintainability, and stable transmission of high-power optical signals in external light source solutions. Against this backdrop, JONHON has launched its external light source optical connector, delivering a high-density, low-loss, professional, and reliable interconnection solution for high-speed interconnect scenarios.

Product Introduction

JONHON's external light source optical connector is specifically designed for ELSFP external light source modules under CPO/NPO architectures. The product consists of two parts: the host-side connector (mounted on the switch PCB motherboard) and the module-side connector (integrated into the pluggable ELSFP light source module). During installation, blind-mate direct plugging is supported without the need for complex debugging.

Product Highlights

1. Ultra-High Density to Support AI Ultra-Large Bandwidth

A single connector set can integrate 2 MT ferrules, accommodating up to 72 PM optical fibers per single port. This maximizes the number of fiber channels within the limited panel space of equipment, significantly increasing port density to perfectly match the explosive bandwidth growth demands of AI computing clusters.

2. Low Optical Loss for Higher Transmission Efficiency

With low-loss ferrules, the product achieves a maximum insertion loss of only 0.35 dB, ensuring highly efficient and stable transmission of high-power optical signals with minimal signal attenuation.

3. Self-Alignment Structure for Easy and Convenient Installation

A multi-stage precision guiding structure enables automatic alignment and precise mating without the need for specialized tools, greatly simplifying assembly and on-site maintenance.

4. Standard Compliance for Compatibility with Mainstream Equipment

The product complies with the OIF-ELSFP-02.0 industry standard, enabling interoperability with equipment from major industry vendors and compatibility with various CPO/NPO commercial devices.

5. Hot-Pluggable Support for Zero-Downtime Maintenance

In the event of a laser failure, there is no need to shut down the entire system—simply plug and replace the module to restore normal operation, significantly reducing data center maintenance costs.

Currently, CPO/NPO technologies have entered a critical phase of commercial deployment and large-scale implementation, with widespread adoption across scenarios such as AI data centers, high-speed switches, smart NICs, and test equipment. Looking ahead, JONHON will continue to deepen its expertise in high-speed fiber optic interconnection, persistently advancing core technologies in high-density, low-loss, and high-reliability optical connectivity. Through continuous product iteration and performance optimization, JONHON is fully committed to empowering AI computing infrastructure with efficient, low-carbon, and high-quality development.
