Features of 32G SFP28 Optical Transceivers
Before I introduce the 32G SFP28 FC transceivers, I would like to introduce you to Fibre Channel technology (FC). Due to its high bandwidth and low latency, Fibre Channel technology plays an important role in the process of high-speed data transmission and timely response. Because of this technology, 32G optical modules have the following characteristics:
High-speed transmission: It supports high-speed data transmission with a real transmission rate of up to 28.05Gbps.
Backwards compatible: Backwards compatible with 8G and 16G Fibre Channel standards.
Flexible application: FC technology supports multiple topologies, enabling 32G optical modules to flexibly adapt to various network scenarios.
Stable and reliable: FC technology with built-in error detection and correction mechanism ensures the accuracy and reliability of 32G optical modules in the process of transmitting information.
Types of 32G SFP28 Optical Modules
32G SFP28 FC Multi-mode Optical Transceivers
Model: 32G SR
Wavelength: 850nm
Transmission Distance:
Maximum link length of 70m via OM3 multimode Fiber (MMF)
Maximum link length of 100m via OM4 multimode Fiber (MMF)
Application Scenarios:
Short-distance applications.
32G SFP28 FC Single-mode Optical Transceivers
32G single-mode optic transceivers have these following models:32G SFP28 LR, 32G SFP28 ER, 32G SFP28 DWDM and 32G SFP28 CWDM. Then I will show you these models:
| Model | Connector | Wavelength | Distance |
| 32G SFP28 LR | LC Duplex | 1310nm | 10KM |
| 32G SFP28 ER | LC Duplex | 1310nm | 40KM |
| 32G SFP28 CWDM | LC Duplex | 1270nm~1610nm | 10KM |
| 32G SFP28 DWDM | LC Duplex | C17~C61 | 10KM |
Application: The 32G LR Optical Module serves as the interconnect for long-haul Fibre Channel switches and HBA Fiber NICs. Scenarios that require longer distances require 32G ER optical transceivers. The CWDM and DWDM are suitable for complex network scenarios that require wavelength multiplexing and long-distance transmission.
Application of 32G SFP28 Optical Transceiver in SAN Storage Network
Enterprise networks have higher and higher requirements for data storage. Based on this, the SAN network came into being. A SAN network is a high-speed private subnet. A SAN storage network connects multiple storage devices together, creating a storage pool that allows multiple servers to share. 32G optical modules play a irreplaceable role in SAN storage networks due to their high efficiency, high speed, good compatibility, and flexible applications. 32G optical transceivers are currently widely employed in telecommunications, meteorology, surveying and mapping, military, radio, etc. These industries have increasing requirements for storage space. This type of module can help these industries build reliable, high-speed, and scalable storage networks. They enable real-time network monitoring, improve information transmission efficiency, and reduce losses and costs.
Conclusion
The above is the introduction to the basic knowledge of 32G SFP28 FC optical modules. We believe that 32G transceivers will play a significant role in more fields in the near future.
