Q1. What is an SFP-1G-SX module?
A: The SFP-1G-SX module is a Small Form-factor Pluggable (SFP) fiber optic transceiver operating at 1Gbps, using an 850nm wavelength over multi-mode fiber (MMF).
Q2. What does "SFP-1G-SX" specifically mean?
A:
- Small Form-factor Pluggable (standard modular interface)
- Gigabit Ethernet (1000 Mbps) speed
- Short wavelength (850nm), Multi-mode fiber, typically up to 550 meters
Q3. What is the typical transmission distance supported by SFP-1G-SX?
A: The module typically supports up to 550 meters over multi-mode fiber (OM2 or better).
Q4. What fiber type and connector does the SFP-1G-SX use?
A: It uses multi-mode fiber (MMF) with dual LC connectors.
Q5. Is SFP-1G-SX compatible with different brands of network equipment?
A: Yes, SFP-1G-SX is fully compatible across most major brands, including Cisco, Huawei, Juniper, Arista, Extreme Networks, HP, and others.
Q6. Does the SFP-1G-SX module support hot-swapping?
A: Yes, SFP-1G-SX modules are hot-swappable, meaning they can be plugged into or removed from a powered network device without interrupting system operation.
Q7. What is the operating temperature range of an SFP-1G-SX module?
A: Standard modules typically operate between 0°C to 70°C (commercial) and extended models from -40°C to 85°C (industrial-grade).
Q8. What is the power consumption of an SFP-1G-SX module?
A: Typical power consumption is around 0.8 to 1W, depending on the manufacturer.
Q9. Does SFP-1G-SX support Digital Diagnostic Monitoring (DDM)?
A: Yes, most modern SFP-1G-SX modules support DDM (also called DOM), allowing real-time monitoring of optical power, temperature, voltage, and module status.
Q10. Can SFP-1G-SX modules run at speeds other than 1Gbps?
A: No, SFP-1G-SX modules are specifically designed to operate at a fixed speed of 1Gbps.
Q11. Are SFP-1G-SX modules compatible with 10Gbps SFP+ slots?
A: Yes, many network devices with SFP+ (10Gbps) slots can accommodate SFP-1G-SX modules to operate at 1Gbps speeds, but it's essential to confirm compatibility with your specific equipment.
Q12. How can I verify compatibility with my network equipment?
A: Compatibility is usually listed in your network equipment’s documentation. Alternatively, modules marked "SFP-1G-SX" generally comply with Multi-Source Agreement (MSA) standards and are widely compatible across brands.
Q13. What applications are SFP-1G-SX modules commonly used for?
A: They are commonly used for Gigabit Ethernet applications, data center interconnects, campus network backbones, and high-speed LANs requiring short-to-medium distance connectivity.
Q14. What fiber optic standards does the SFP-1G-SX comply with?
A: The SFP-1G-SX modules comply with IEEE 802.3z standard for Gigabit Ethernet 1000BASE-SX, ensuring broad interoperability across equipment.
Q15. Do SFP-1G-SX modules require specific software configurations on network devices?
A: Typically, no specialized configuration is required beyond inserting the module and ensuring the port is enabled. However, device-specific firmware or compatibility checks might occasionally be necessary.
