It uses one LC connector and supports rated links up to 20 km. The transmit wavelength is 1550 nm and the receive wavelength is 1310 nm. EtherWAN specifies optical output power of -8 to -2 dBm, receiver sensitivity of -23 dBm, and a nominal 15 dB optical link budget. Digital Diagnostic Monitoring is supported, with an operating temperature range of -40°C to +85°C. The complementary SFPGYS20M uses 1310 nm TX and 1550 nm RX. Compatible Gigabit SFP hosts, appropriate remote optics, and sufficient optical margin are required.\n  \u003c\/p\u003e\n\n  \u003c!-- HERO IMAGE --\u003e\n  \u003cdiv class=\"cm-hero\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGZS20M.webp?v=1792997354\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGZS20M.webp?v=1792997354\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGZS20M.webp?v=1792997354\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGZS20M.webp?v=1792997354\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN SFPGZS20M hardened Gigabit BiDi SFP with simplex LC for 20 km fiber links\" loading=\"lazy\" decoding=\"async\"\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- KEY FEATURES --\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\n  \u003cdiv class=\"cm-feature-grid cm-feature-grid--2col\"\u003e\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e1 Gbps Gigabit Ethernet Connectivity\u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The SFPGZS20M supports Gigabit Ethernet over compatible SFP network equipment.
