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

We ordered these for a multi-brand switch compatibility project. The product page lists support for platforms from Cisco, Arista, Aruba, Juniper, Dell, HPE, Fortinet, and others, which made it a useful candidate for our lab. The actual host coding should still be confirmed before a large deployment.

The module performed well in our indoor telecom equipment room. We needed 1G connectivity over a long single-mode fiber run and specifically wanted 1550nm with an 80km reach. The Duplex LC interface matched our existing patch panel, so the physical installation was simple.

We were replacing older long-distance 1G optics and wanted something with a standard SFP footprint. These modules matched the requirement well: 1.25Gbps, 1550nm, Duplex LC, SMF, and up to 80km. Testing was straightforward. ;)

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 optic works well and the specifications matched our requirements. I only took one star off because the shipment packaging had a small dent, although the transceiver itself arrived protected and passed our installation test.

The distance is the standout feature here. An 80km 1550nm SFP is exactly what we were looking for for a long fiber route where shorter-reach 1G modules were not enough. Installation was straightforward, and the Duplex LC connector matched our existing fiber panels.

We used this 1.25Gbps SFP for a long-distance campus fiber link. The existing single-mode fiber and Duplex LC patching were already in place, so installation was basically plug-and-test. DOM also gave us useful visibility during commissioning.

Nice balance of reach, monitoring, and cost. We needed a 1.25Gbps 1550nm optical transceiver for a long-distance SMF link rather than a higher-speed optic. The module fit our SFP ports, worked with Duplex LC cabling, and gave us the diagnostics we wanted. :-D
