Solid purchase

The optical transceiver meet expectations. Slight noise, but nothing major. Store handled order smoothly. Could use clearer LEDs. Manual could be better organized.

B

Frequently Questions and Answers

Q1. What is an SFP‑25G‑SR‑S module?

A: The SFP‑25G‑SR‑S is an SFP28 transceiver module supporting 25 Gbps Ethernet over multimode fiber (MMF) at 850 nm wavelength, compliant with 25GBASE‑SR standards.

Q2. What is the maximum supported transmission distance?

A: Supports up to 70 m on OM3 and 100 m on OM4 multimode fiber at 25 Gbps. RS‑FEC (Reed‑Solomon Forward Error Correction) on host ports is required to achieve the full reach.

Q3. What connector and fiber type are used?

A: It uses LC duplex connectors over 50/125 µm multimode fiber (MMF) like OM3 or OM4.

Q4. Is SFP‑25G‑SR‑S compatible across brands?

A: Yes. It is MSA-compliant and works with major vendors such as Cisco, Arista, Juniper, Huawei, Dell, Extreme, etc., given their equipment supports 25 Gbps optics.

Q5. Does it support hot-swapping?

A: Yes, as an SFP28 module it is fully hot-pluggable, allowing insertion/removal without shutting down host equipment.

Q6. Does SFP‑25G‑SR‑S support Dual‑rate (10/25G) operation?

A: Yes, many compatible versions support dual-rate operation, allowing them to work at both 10 Gbps and 25 Gbps speeds (e.g., IEEE‑compliant fallback mode).

Q7. Does it support Digital Diagnostic Monitoring (DDM/DOM)?

A: Yes. SFP‑25G‑SR‑S modules typically support DOM/DDM via SFF‑8472, enabling monitoring of optical power, temperature, voltage, etc.

Q8. What is the power consumption of the module?

A: Typical maximum power consumption is around 1.2 W, depending on vendor and operation mode.

Q9. What temperature range is supported?

A: Standard commercial grade supports 0 °C to 70 °C. Industrial variants may offer extended ranges (e.g., –40 °C to 85 °C) depending on vendor specifications.

Q10. Which IEEE/Multi‑Source Agreements does SFP‑25G‑SR‑S conform to?

A: Conforms to IEEE 802.3by (25GBASE‑SR), and SFP28 MSA SFF‑8402, along with SFF‑8431/8432/8472 for form factor and diagnostic protocols.

Q11. How to verify compatibility with my equipment?

A: Check that your switch or NIC supports 25GBASE‑SR optics and accepts generic/third-party SFP28 modules without firmware restrictions. Compatibility lists often include this module’s part number or equivalent.

Q12. What applications is SFP‑25G‑SR‑S ideal for?

A: Ideal for data center top-of-rack/inter-rack uplinks, high-throughput SANs, server-to-switch and switch-to-switch links in high-density rack deployments.

Q13. Can SFP‑25G‑SR‑S auto-negotiate to 10G?

A: Yes, dual-rate versions can operate at 10.31 Gbps (10GBASE‑SR) where supported by host hardware. However, operating distance for 10G may extend slightly based on fiber quality and FEC requirement.

Q14. Is RS‑FEC required for full distance at 25G?

A: Yes—full 70–100 m reach on OM3/OM4 requires RS‑FEC enabled on host ports as per IEEE802.3by clause requirements.
