Frequently Questions and Answers

Q1. What is an SFP‑1G‑LX module?

A: The SFP‑1G‑LX module is a Small Form‑factor Pluggable (SFP) transceiver designed for 1 Gbps (Gigabit Ethernet) communication over single‑mode fiber (SMF), using a 1310 nm wavelength.

Q2. What does the model code "SFP‑1G‑LX" mean?

A:

  • Small Form‑factor Pluggable modular interface
  • Supports 1 Gbps (1000 Mbps) data rate
  • Long‑range transmission, using 1310 nm wavelength over single‑mode fiber

Q3. What is the maximum supported transmission distance?

A: Typical maximum distance is 10 km over SMF at 1310 nm; some high‑optical‑budget variants can reach 20 km.

Q4. Can the SFP‑1G‑LX module work over multi‑mode fiber (MMF)?

A: Yes, it can operate over MMF (up to ~550 m) with a mode-conditioning patch cord, though it is optimized for SMF.

Q5. What connector type does SFP‑1G‑LX use?

A: It uses a duplex LC connector for fiber interfaces.

Q6. Is SFP‑1G‑LX compatible with all brands of networking equipment?

A: Yes, it complies with the MSA SFF‑8477 standard, making it compatible with major brands like Cisco, Juniper, Arista, Huawei, HP, Dell, etc.

Q7. Does SFP‑1G‑LX support hot‑swapping?

A: Yes, it is hot‑plug capable, allowing insertion or removal without powering off the switch or router.

Q8. What is the typical power consumption?

A: Power consumption is typically < 1.3 W, often around 1.0 W or less depending on vendor.

Q9. Does the module support Digital Diagnostic Monitoring (DDM/DOM)?

A: Yes, most SFP‑1G‑LX modules support DDM (SFF‑8472), enabling real‑time monitoring of optical parameters like power, temperature, voltage, etc.

Q10. Can SFP‑1G‑LX operate in multi‑rate devices or Mixed‑speed slots?

A: Typically it's fixed at 1 Gbps. Some modules support dual rate (1.25 Gbps) for Fibre Channel and Ethernet usage, but do not auto‑negotiate down to 100 Mbps.

Q11. What is the operating temperature range of SFP‑1G‑LX modules?

A: Standard commercial modules operate from 0 °C to 70 °C, while industrial‑grade versions may support −40 °C to 85 °C.

Q12. How can I verify compatibility with my networking device?

A: Check the device’s documentation for supported modules. If it supports generic 1000BASE‑LX SFP and not locked to vendor‑branded optics, you can use a Multi‑Source Agreement compliant module.

Q13. What applications are typical for SFP‑1G‑LX modules?

A: Common in campus backbone links, inter-building connections, metro and ISP networks, enterprise LANs, SAN backplanes, and telecom-grade deployments.

Q14. What IEEE standard defines SFP‑1G‑LX functionality?

A: It adheres to IEEE 802.3z clause for 1000BASE‑LX/LH, specifying 1310 nm operation up to ~5 km (standard), extended to ~10 km (“LX10”/LH).

Q15. Are there variants of SFP‑1G‑LX offering longer reach?

A: Yes, certain 20 km variants (1310 nm, FP laser) are available which exceed standard 10 km reach when using high optical budget SMF.
