SFP 25G SR
Products Description
This SFP 25G SR optical transceiver is designed as a high-performance, cost-effective solution for next-generation data center interconnects, specifically addressing the need for increased bandwidth in server-to-top-of-rack (ToR) switch connections. Supporting a data rate of 25.78 Gbps, it provides a critical 2.5x bandwidth upgrade over traditional 10G SFP+ links while maintaining the same compact form factor and leveraging existing multi-mode fiber infrastructure. The module is engineered for high-density deployments where low latency, low power consumption, and reliability are paramount.
Featuring an 850nm VCSEL transmitter paired with a high-sensitivity GaAs PIN photodiode receiver, it ensures robust signal integrity for reaches up to 70 meters on OM3 and 100 meters on OM4 multi-mode fiber. Its design incorporates internal Clock and Data Recovery (CDR) units on both transmit and receive paths, which are crucial for maintaining low jitter and a low bit-error rate in high-speed applications. Operating from a single 3.3V power supply within a wide temperature range of 0°C to 70°C, this hot-pluggable transceiver is fully compliant with SFP28 MSA, SFF-8431, and SFF-8432 standards. It also meets Class 1 laser safety requirements, offering a future-proof and efficient building block for scalable 25G Ethernet and storage networks.
FAQ
Q: What does "internal CDR" (Clock and Data Recovery) mean for our network stability?
A: Think of CDR as a built-in signal "clean-up" crew. It reduces jitter (tiny timing imperfections in the signal) that accumulates over distance and through connectors. This results in a cleaner, more stable signal at the receiver, which translates to a lower bit-error rate and greater overall link reliability, which is crucial for high-speed data.
Q: How does this SFP 25G SR compare to a 10G SFP+ SR module in terms of physical installation? Is it more delicate?
A: The physical installation process is identical and equally robust. It uses the same SFP form factor and LC duplex connectors. There is no increased delicacy. The key difference is the higher performance requirement for fiber cleanliness. Because it operates at a higher data rate, dust or contamination on the connectors is more likely to cause errors, so following proper cleaning procedures is even more important.
