Questions & Answers

Ask a Question
No data
  • Q: Can this 1550nm SFP really support an 80km fiber link? By N***s on 2026-05-04

    A: Yes. The LS-SM551G-80C is specified for up to 80km over single-mode fiber at 1550nm, with a 1.25Gbps maximum data rate. Actual link distance depends on the fiber plant, connectors, splices, and overall optical loss budget. By admin on 2026-05-05

  • Q: What type of fiber and connector should I use with this module? By H***r on 2025-02-21

    A: It uses single-mode fiber (SMF) and a Duplex LC interface. The transmitter is a 1550nm DFB laser and the receiver uses a PIN photodetector. By admin on 2025-02-21

  • Q: Can I use this in an industrial or outdoor cabinet? By C***k on 2024-08-21

    A: If your application requires the industrial temperature range, specify the industrial version (such as LS-SM551G-80I) when ordering rather than assuming the standard LS-SM551G-80C has the extended range. By admin on 2024-08-21

  • Q: Does it support DOM, and which switch brands can I order it coded for? By N***s on 2024-04-15

    A: Yes, the LS-SM551G-80C supports DOM and SFF-8472 digital diagnostics. The product page lists compatibility with Cisco, Arista, Aruba, Juniper, HPE, Dell, Fortinet, NVIDIA/Mellanox and other platforms. For a specific switch model, confirm the required OEM coding before placing a bulk order. By admin on 2024-04-15

We ordered these for a multi-brand switch compatibility project.

The actual host coding should still be confirmed before a large deployment.

We chose this for an enterprise fiber network where some remote cabinets are far beyond normal 1G multimode distances. Using 1550nm single-mode fiber with an 80km-rated SFP gave us plenty of reach. The DOM feature has also been useful for tracking optical performance during maintenance.

The 1550nm 80km specification was the main reason we selected this module. Our route is well beyond what a typical 10km or 20km 1G optic can cover, so the extra reach is useful. It also fits the standard SFP slot without changing the switch platform.

The DOM support is a big plus for our operations team. We can check optical parameters from the host equipment instead of sending someone to the cabinet every time we need basic link diagnostics. The 80km reach also gives plenty of headroom for our current route.
