EtherWAN specifies a 70 km distance, 9\/125 µm single-mode fiber, duplex LC connector, 1550 nm wavelength, DDM, 23 dB optical link budget, 0 to +5 dBm transmitter output and -23 dBm receiver sensitivity. Operating temperature is 0°C to +70°C. A historical EtherWAN end-of-life notice identifies this part as a replacement model for older SFPs; that notice does not establish an end-of-life date for this model. Coremicro lists it as Special Order; verify current pricing, availability and warranty coverage before purchasing.\n  \u003c\/p\u003e\n\n  \u003c!-- HERO: ONE SHOPIFY CDN IMAGE --\u003e\n  \u003cdiv class=\"cm-hero\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX-LS48-C3U-TC-N-EB.webp?v=1793068322\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX-LS48-C3U-TC-N-EB.webp?v=1793068322\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX-LS48-C3U-TC-N-EB.webp?v=1793068322\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-EX-LS48-C3U-TC-N-EB.webp?v=1793068322\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN EX-LS48-C3U-TC-N-EB 70 km Gigabit SFP with 1550 nm duplex LC and DDM\" loading=\"lazy\" decoding=\"async\"\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- KEY FEATURES: LAYOUT 3 --\u003e\n  \u003cdiv class=\"cm-section-label\"\u003e\n\u003cdiv class=\"cm-section-label__bar\"\u003e\u003c\/div\u003e\n\u003cspan class=\"cm-section-label__text\"\u003eKey Features\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"cm-feature-grid cm-feature-grid--2col\"\u003e\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003cdiv class=\"cm-feature-box__icon\"\u003e🔗\u003c\/div\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e70 km Single-Mode Fiber Reach\u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003eThe 70 km Gigabit SFP rating supports long-distance Ethernet links over 9\/125 µm single-mode fiber.
