Use Cases for AOI 100Gbps PSM4 Transceiver

• High-speed 100G connectivity in hyperscale data centers

• Spine-to-leaf switch links in cloud environments

• Server-to-switch aggregation layers

• Interconnecting 100G switches in enterprise and telecom networks

• Supporting AI/ML workloads with large east-west data traffic

Thanks to its 4-lane parallel transmission, it’s perfect for reducing bottlenecks in modern distributed applications and big data pipelines.

Performance and Reliability with PSM4 Technology

The PSM4 (Parallel Single-Mode 4-lane) standard transmits four independent optical signals on separate fibers, each carrying 25Gbps for a total of 100Gbps. This design minimizes optical dispersion and signal degradation, making it ideal for medium-range deployments of up to 500 meters.

Compared to other 100G technologies like CWDM4 and SR4, the PSM4 module offers a balanced tradeoff between cost, complexity, and distance, especially in data centers where single-mode infrastructure is already available.

Advantages of Choosing AOI 100Gbps PSM4

• Interoperability: Works seamlessly with all 100G QSFP28 ports compliant with PSM4 MSA.

• Energy Efficiency: Operates at lower power levels, reducing heat and cooling costs.

• Ease of Deployment: MPO interface and hot-swappable design enable plug-and-play functionality.

• Digital Monitoring: DDM support allows real-time tracking of key operating parameters.

• Scalability: Enables smooth transition to 100G without overhauling existing infrastructure.

Long-Term Value and Investment Protection

Choosing the AOI 100Gbps PSM4 transceiver means investing in a future-ready, high-performance optical solution that meets the evolving demands of next-generation networks. Its compliance with industry standards ensures longevity and backward compatibility, while its parallel single-mode architecture offers room for growth without overhauling existing fiber infrastructure. This makes it ideal for organizations planning a smooth transition to 400G or 800G environments in the future, where modularity and flexibility will be essential.

Additionally, the transceiver’s durability and support for digital optical monitoring allow for predictive maintenance, reducing downtime and support costs over time. For network administrators and architects, this means fewer surprises, improved reliability, and the confidence that each optical link delivers stable, low-latency performance under peak loads.

In a competitive IT landscape where network agility, speed, and cost efficiency are non-negotiable, the AOI 100Gbps PSM4 stands out as a reliable cornerstone in building scalable and robust 100G optical backbones.

Seamless Integration in Enterprise Networks

The AOI 100Gbps PSM4 transceiver supports easy integration into top-of-rack (ToR), middle-of-row (MoR), and end-of-row (EoR) switch designs. It is particularly suitable for network operators aiming to increase east-west traffic bandwidth in virtualized environments and microservices-based applications.

Its proven reliability and AOI’s strict quality control processes make this module an excellent choice for businesses that prioritize network uptime and future-proof investments.
