Fs.com SFP1G-ZX-55, 1000BASE-ZX SFP 1550nm 80km Duplex LC/UPC SMF Transceiver - solving distance limits for modern networks

When your fibre runs exceed the reach of standard 1000BASE-SX or -LX modules, signal loss becomes a real barrier to growth. This limits the ability to connect remote offices, data-centre extensions or outdoor sites, forcing you to add costly repeaters or redesign the network. The Fs.com SFP1G-ZX-55, 1000BASE-ZX SFP 1550nm 80km Duplex LC/UPC SMF Transceiver eliminates that barrier by delivering a clear, high-quality optical signal over distances up to 80 km on standard single-mode fibre. Its DFB laser source and robust design meet both SFF-8472 MSA and IEEE 802.3ah-2004 standards, ensuring compatibility and dependable performance in demanding environments.

Benefits 

You gain the confidence of a proven 1.25 Gbps data rate that handles typical Ethernet traffic with ease. The 1550 nm wavelength and DFB laser ensure low attenuation, so the signal stays strong even at the maximum 80 km span. Built-in DOM support lets you monitor temperature and optical power in real time, helping you prevent failures before they happen. The wide commercial temperature range of 0 °C to 70 °C means the module performs reliably in both data-centre and outdoor installations. Finally, its generic compatibility means you can use it with a broad range of network gear, protecting your investment.
