This makes it ideal for mid-range deployments between network switches, routers, and high-performance computing infrastructure within a data center.

Technology Behind QSFP28 and PSM4

Understanding QSFP28 Module Form Factor

QSFP28 (Quad Small Form-factor Pluggable 28) is a compact, hot-pluggable transceiver form factor designed for 100G data transmission. The "28" in QSFP28 refers to the maximum data rate of 28 Gbps per lane. The transceiver supports four lanes of 25 Gbps, typically running at 100Gbps total bandwidth. QSFP28 is backward compatible with QSFP+, allowing for simplified upgrades in modular networking environments. Its small footprint makes it well-suited for high-density data center installations.

Parallel Single-Mode 4-lane (PSM4) Explained

The PSM4 standard uses four parallel lanes over single-mode fiber (SMF), each transmitting and receiving 25 Gbps. PSM4 modules typically operate at a wavelength of 1310nm, and unlike WDM-based technologies that use multiple wavelengths, PSM4 simplifies design and lowers cost by using a single wavelength across all lanes. The result is reduced complexity in optical components and decreased power consumption.

Advantages of PSM4 Architecture

• Lower cost per bit for mid-range optical interconnects
• Support for simplified fiber infrastructure using parallel SMF
• Improved reliability due to simpler optical design
• High scalability potential for hyperscale data centers

Applications and Use Cases in Modern Data Centers

Optimizing Inter-Switch Links (ISLs)

The Q8J73-63001 is commonly used for creating high-bandwidth inter-switch links in leaf-spine architectures. Its 500-meter range makes it perfect for connecting switches across large data halls or between separate cages in the same data center facility.

High-Performance Computing (HPC)

In HPC environments, rapid data movement between compute nodes and storage resources is critical. The transceiver supports ultra-fast, low-latency communication over single-mode fiber, optimizing performance for tasks such as scientific simulations, AI training, and data modeling.

Data Center Backbone Infrastructure

As organizations expand their infrastructure, the need for efficient and scalable backbones grows. This transceiver offers a cost-effective way to expand bandwidth while maintaining energy efficiency and consistent signal integrity.

Cloud Computing and Virtualization

Cloud service providers and virtualized environments benefit from the high throughput and low power characteristics of the Q8J73-63001. It reduces network bottlenecks and ensures high availability, critical for delivering Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).

Deployment and Installation Best Practices

Fiber Cabling Requirements

Installation of this transceiver requires MPO-12 APC-terminated single-mode fiber cables. Ensure clean and properly polished connectors to maintain optimal signal performance and avoid degradation over time. Use of proper fiber cleaning tools and inspection scopes is essential.

Environmental and Power Considerations

This transceiver is designed for environments operating within 0°C to 70°C. Proper airflow and power distribution must be ensured to maintain the component's longevity and reduce the risk of overheating or failure. The module typically consumes less than 3.5W, making it ideal for high-density deployments without imposing heavy cooling demands.

Insertion and Removal Process

QSFP28 modules are hot-swappable. To insert, gently align and push the module into the port until it clicks. To remove, pull the tab or lever (depending on the model) and slide the module out gently. Always ensure the module is disconnected from the fiber cable before removal to prevent damage.

Compatibility with HPE and Other Networking Equipment

Supported HPE Platforms

• HPE ProLiant Gen10 and Gen11 Servers
• HPE Synergy Interconnect Modules
• HPE BladeSystem Enclosures

Interoperability with Third-Party Devices

While optimized for HPE hardware, the Q8J73-63001 is compliant with industry standards and may function with non-HPE equipment that supports QSFP28 PSM4. However, cross-vendor compatibility should be validated through testing, as firmware restrictions may apply.

Software and Firmware Support

Ensure the latest firmware updates are applied to networking gear to enable optimal compatibility and performance. HPE periodically releases firmware packages that include transceiver support enhancements and bug fixes.

Comparing PSM4 with Other 100G Optical Technologies

PSM4 vs. CWDM4

CWDM4 uses Coarse Wavelength Division Multiplexing to send signals across four different wavelengths over a duplex pair of SMF fibers, typically supporting distances up to 2 km. PSM4, in contrast, uses eight fibers—four transmit and four receive—all operating at 1310nm. Though PSM4 requires more fiber strands, it is typically more cost-effective over short to mid-range deployments.

PSM4 vs. SR4 (Short Reach)

SR4 uses multimode fiber (MMF) and is limited to 70–100 meters, making it suitable for very short distances. PSM4, with its 500m reach on SMF, offers a broader deployment range and is better suited for large data centers and campus interconnects.

PSM4 vs. LR4 (Long Reach)

LR4 modules use WDM to transmit signals over four wavelengths and can reach up to 10 km. While PSM4 has shorter reach, it is significantly more affordable and simpler in design, ideal for use cases that do not require long-haul performance.

Power Efficiency and Thermal Performance

Low Power Consumption Benefits

Operating below 3.5W, the Q8J73-63001 helps reduce power draw in high-density switch and server environments. In large-scale deployments, this efficiency translates to measurable OPEX savings and reduced environmental impact.

Heat Dissipation and Cooling Requirements

Effective thermal design is critical for ensuring long-term performance. This transceiver incorporates built-in heat sinks to aid in thermal management. Data centers should use properly cooled enclosures with front-to-back airflow to maintain safe operating temperatures.
