Overview of 32G SFP28 Fibre Channel Modules
Our 32G SFP28 modules are high-performance transceivers specifically engineered for the demands of modern Storage Area Networks (SANs). They operate at a line rate of 28.05 Gbps to deliver full 32G Fibre Channel (32GFC) throughput. Consequently, these modules are essential for connecting servers, storage arrays, and SAN switches. This provides the high bandwidth and low latency required for mission-critical applications and data-intensive workloads. In short, they are the backbone of a high-performance storage fabric.
Furthermore, a critical feature of our 32G SFP28 transceivers is their full backward compatibility. They can auto-negotiate to operate at 16GFC and 8GFC speeds. This allows for a flexible and cost-effective upgrade path for existing SAN infrastructure. Therefore, you can introduce 32G capabilities where needed without having to overhaul your entire network at once. All our modules are built to MSA standards, ensuring they are fully interoperable with a wide range of host equipment.
Key Features
- High-Speed 32GFC Performance: First and foremost, experience true 32G Fibre Channel speed. This enables rapid data transfer and significantly reduces storage bottlenecks.
- Multi-Rate Auto-Negotiation: In addition, these modules are fully backward compatible. They seamlessly operate with existing 16GFC and 8GFC SAN infrastructure, which protects your investment.
- Short Reach (SR) and Long Reach (LR) Options: Select the right module for your needs. Choose SR for connections up to 100 meters within a data center rack, or LR for links up to 10km between different sites.
- Ultra-Low Latency: Specifically, Fibre Channel demands minimal delay. Our modules are designed for the ultra-low latency that is critical for storage applications like database transactions and virtualization.
- Hot-Pluggable SFP28 Form Factor: The compact SFP28 footprint allows for high port density. Moreover, its hot-pluggable nature means you can install or replace modules without powering down your SAN switch.
- Digital Diagnostics Monitoring (DDM/DOM): Lastly, all modules provide real-time monitoring of key operational parameters. This includes optical power, temperature, and voltage, which aids in proactive network maintenance.
Applications
Indeed, 32G SFP28 modules are purpose-built for high-performance storage networking. Their primary applications include:
- Storage Area Network (SAN) Fabrics: For instance, they form the high-speed links between Fibre Channel directors and switches, creating a robust storage fabric.
- Server to Fabric Connectivity: They connect Host Bus Adapters (HBAs) in servers directly to the SAN, giving applications fast access to storage resources.
- Storage Array Connectivity: Similarly, they are used in the front-end ports of storage arrays (like All-Flash Arrays) to provide high-throughput data access.
- Data Center Core Networks: They provide the essential interconnectivity within and between data centers for storage replication and disaster recovery tasks.

FAQ (Technical & product category Questions)
1. What is 32G Fibre Channel (32GFC)?
32GFC is a generation of the Fibre Channel protocol that provides a data transfer rate of 3,200 MB/s per direction. It is designed specifically for high-speed, reliable, and low-latency communication in Storage Area Networks (SANs). In essence, it is the modern standard for enterprise storage.
2. Can I use a 32G SFP28 module in a 16GFC port?
Yes, absolutely. One of the main benefits of 32G SFP28 modules is their backward compatibility. When you plug one into a switch port configured for 16GFC, it will auto-negotiate down to operate at 16GFC speed. This makes network upgrades much simpler.
3. What is the difference between 32GFC SR and 32GFC LR?
The main difference is the distance and fiber type they support. A 32GFC SR (Short Reach) module uses a lower-cost 850nm laser and is designed for short distances up to 100 meters over Multimode Fiber (MMF). In contrast, a 32GFC LR (Long Reach) module uses a 1310nm laser for distances up to 10km over Single-Mode Fiber (SMF).
4. Can I use this 32G SFP28 module for 25G Ethernet?
No. Although they share the same SFP28 physical form factor, 32GFC and 25G Ethernet are different protocols. A 32GFC module is programmed with firmware specifically for the Fibre Channel protocol and will not function in an Ethernet port. Likewise, a 25G Ethernet SFP28 will not work in a 32GFC port.
5. What is a Host Bus Adapter (HBA)?
A Host Bus Adapter, or HBA, is a circuit board or integrated circuit that connects a host system, like a server, to a storage network. In this context, a Fibre Channel HBA would have SFP28 ports where you would install these 32G SFP28 transceivers to connect the server to a SAN switch.
6. Why is compatibility with Brocade and Cisco MDS important?
Brocade and Cisco are the two dominant manufacturers of Fibre Channel SAN switches and directors. Therefore, ensuring our 32G SFP28 modules are programmed to be fully compatible with their equipment is critical. It guarantees plug-and-play functionality and reliable performance within the vast majority of enterprise SANs.
