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
