What is a 1.6T OSFP224 InfiniBand XDR transceiver?

A 1.6T OSFP224 InfiniBand XDR transceiver is a high-speed optical module designed for next-generation InfiniBand XDR networks in AI, HPC, and large-scale data center environments. It uses the OSFP224 form factor and supports 1.6Tb/s aggregate bandwidth, helping connect GPU servers, switches, and compute clusters with low-latency, high-density optical links.

What is the difference between 2xDR4/DR8 and 2xFR4/FR8?

2xDR4/DR8 modules are typically designed for shorter single-mode fiber links, such as up to 500m, and use dual MTP/MPO-12 APC connectors. 2xFR4/FR8 modules are designed for longer reaches, such as up to 2km, and commonly use dual LC duplex connectors. The right choice depends on your link distance, cabling infrastructure, connector type, and switch-to-server or switch-to-switch deployment design.

Which reach should I choose: 500m or 2km?

Choose 500m 2xDR4/DR8 modules when your deployment is within the same data hall, between nearby racks, or across short single-mode fiber runs. Choose 2km 2xFR4/FR8 modules when you need longer-distance connections between rooms, buildings, zones, or larger campus data center areas. If you are unsure, confirm the actual fiber distance, connector type, patch panel design, and link budget before selecting the module.

Are these modules suitable for AI and HPC clusters?

Yes. 1.6T OSFP224 InfiniBand XDR transceivers are suitable for AI training clusters, HPC systems, GPU fabrics, and high-bandwidth data center interconnects that require fast, stable, and scalable optical connectivity. They are especially relevant for environments where high throughput, low latency, dense port deployment, and reliable thermal performance are important.

1.6T OSFP224 InfiniBand XDR Overview

AICPLIGHT 1.6T OSFP224 InfiniBand XDR optical transceivers are designed for next-generation AI data centers, HPC systems, and GPU clusters that require high-density, low-latency optical connectivity. Based on the OSFP224 form factor, these modules support up to 1.6Tb/s aggregate bandwidth for high-speed InfiniBand XDR network deployments. The series includes 2xDR4/DR8 options for up to 500m single-mode fiber links with dual MTP/MPO-12 APC connectors, as well as 2xFR4/FR8 options for up to 2km links with dual LC duplex connectors. These transceivers help connect GPU servers, InfiniBand switches, and compute nodes across short- and medium-reach data center architectures. For network planning, the right model should be selected based on link distance, connector type, fiber infrastructure, thermal requirements, and switch compatibility.
