Comprehensive Guide to FS 25G SFP28 Transceivers in Data Centers

GeorgeUpdated at Dec 30th 20241 min read

The FS 25G SFP28 transceiver uses the small form-factor pluggable 28 form factor, which is compatible with traditional SFP+ (10G) interfaces. This form factor supports higher data rates and lower power consumption while maintaining a compact design, enabling high-density deployment in switch or server ports. It supports 25Gbps Ethernet and other high-speed data transmission applications, making it widely used in data centers, enterprise networks, and telecommunications environments to meet the growing demand for higher bandwidth and efficient connectivity.
This article focuses on the application of 25G SFP28 transceiver modules and cables in data centers and recommends specific products for you.
Key Advantages of FS 25G SFP28 Transceivers
Strict Testing For Superior Performance
The FS 25G SFP28 transceiver undergoes comprehensive and rigorous performance testing to ensure its exceptional quality and reliability. These tests include performance, reliability, and compatibility testing. In performance testing, FS carries out thorough tests of various aspects of the transceiver, such as wavelength, power, flow, eye diagram situation, and bit error rate (BER). The rigorous testing is conducted using world-class professional equipment, ensuring that customers receive products of the highest quality. In reliability testing, FS simulates real-world transport and installation conditions to assess the module's temperature resistance and impact resistance, verifying its stability in extreme environments. For compatibility testing, the transceiver is tested with over 200 different brand switches to guarantee plug-and-play functionality and perfect compatibility. Through these stringent tests, the FS 25G SFP28 transceiver is capable of stable operation in data centers, providing users with high-performance and reliable network solutions.
Extensive Compliance with Industry Standards
The FS 25G SFP28 transceiver strictly adheres to the IEEE 802.3by and IEEE 802.3cc standards, enabling seamless interoperability with other standardized 25G interfaces for efficient high-speed 25G connections. Additionally, it follows the SFP28 MSA protocol and supports hot-swapping, enhancing the flexibility of network deployment. The product also complies with Class 1 FDA laser safety and RoHS environmental standards, ensuring both safety and eco-friendliness. By fully conforming to industry standards, the FS 25G SFP28 transceiver not only guarantees compatibility and flexibility but also provides users with a safe, reliable, and sustainable network upgrade solution.

FS 25G SFP28 Data Center Connectivity Solutions
FS offers a wide range of 25G data center connectivity solutions, which are highly adaptable to next-generation data center architectures such as Top-of-Rack (TOR), Middle-of-Row (MOR), and End-of-Row (EOR). These architectures typically utilize 25G connections between switches, servers, and network interface cards (NICs), supporting a variety of transmission distances ranging from a few meters to several hundred meters. Below are some common connectivity solutions:
Short-Distance Connections (Up to 5 meters):
For short-distance connections between servers and switches, FS 25G SFP28 Direct Attach Copper (DAC) cables are the ideal choice. These DAC cables comply with IEEE P802.3by Ethernet standards and SFP28 MSA specifications, ensuring compatibility and high performance. They require no additional optical modules, providing a plug-and-play solution with low latency and low power consumption.
Medium-Distance Connections (5 meters to 30 meters):
For medium-distance connections, FS offers 25G SFP28 Active Optical Cables (AOC). These AOC cables support longer transmission distances, up to 30 meters, and are highly resistant to electromagnetic interference while maintaining high bandwidth and low latency. They also adhere to the SFP28 MSA standard, ensuring compatibility with a wide range of network devices.
Long-Distance Connections (Over 30 meters):
For long-distance transmission, FS 25G SFP28 transceivers combined with fiber optic patch cables are the optimal solution. For EOR or inter-building connections, 25G SFP28 transceivers paired with single-mode fiber (SMF) or multi-mode fiber (MMF) are recommended. For instance, 25G BiDi transceivers simplify cabling in bidirectional single-fiber scenarios while reducing costs. The 25G SR transceiver is suitable for high-performance connections over multi-mode fiber up to about 100 meters, while the 25G LR transceiver supports transmission over single-mode fiber up to 10 kilometers.
Through FS diverse product offerings and flexible connectivity solutions, customers can select the most suitable products and solutions based on their data center’s varying distance and bandwidth requirements. Additionally, FS provides 24/5 expert support, offering technical assistance and guidance, with some products available for free trials. This reflects FS’s comprehensive consideration of customer needs, providing full support from all aspects to ensure reliable and efficient solutions.
