Q1. What is an SFP‑10G‑SR module?
A: The SFP‑10G‑SR is a Small Form-factor Pluggable (SFP+) transceiver that supports 10 Gbps Ethernet over multimode fiber (MMF) at 850 nm wavelength.
Q2. What connector and fiber type does it use?
A: Uses duplex LC connector over multimode fiber (50/125 µm).
Q3. Is SFP‑10G‑SR compatible with various vendors?
A: Yes—it's MSA‑compliant and broadly compatible with Cisco, Arista, Juniper, Meraki, Huawei, and other OEMs that support generic 10G-SR module.
Q4. Does SFP‑10G‑SR support hot-swapping?
A: Yes. It is a hot-pluggable SFP+ module, allowing insertion/removal without powering down the device.
Q5. Does it support Digital Diagnostic Monitoring (DDM/DOM)?
A: Yes. Most SFP‑10G‑SR modules include DDM/DOM support via SFF‑8472 for monitoring optical power, temperature, voltage, etc.
Q6. What data rates are supported?
A: Designed for 10 Gbps, but many modules support nominal speeds ranging from 1.25 Gbps to 10.31 Gbps, including Gigabit Ethernet compatibility in some cases.
Q7. What is its typical power consumption?
A: Power is supplied via standard 3.3 V, typical consumption around <1 W or low—vendor dependent.
Q8. What temperature ranges do variants support?
A: Standard commercial modules support 0 °C to 70 °C, and industrial variants may operate from –40 °C to 85 °C.
Q9. What IEEE or MSA standards does it conform to?
A: Conforms to IEEE 802.3ae for 10GBASE-SR, and SFP+ MSA SFF‑8431/SFF‑8472 for form factor and diagnostics.
Q10. How to verify compatibility with my equipment?
A: Check if your device supports generic 10G-SR SFP+ optics and backward compatibility. Modules labeled SFP‑10G‑SR from MSA‑compliant vendors typically work across most brands.
Q11. What applications are common for SFP‑10G‑SR?
A: Ideal for data center uplinks, server connectivity, backbone links in campus/MAN networks, and high-speed LAN applications over multimode fiber.
Q12. Can a SFP‑10G‑SR interoperate with 1 Gbps SR modules?
A: Some devices allow downshifting to Gigabit speeds (e.g. 1.25 Gbps compatibility), but this depends on the switch port capabilities and supported rates.
Q13. Are there temperature-extended or industrial-grade variants?
A: Yes, certain versions are certified for industrial environments with extended temperature ranges and more robust specifications.
