Designed for 1 Gbps communication over 9\/125-micron single-mode fiber, this module uses a duplex LC connector and a 1550 nm optical wavelength to support rated links up to 90 kilometers. With Digital Diagnostic Monitoring (DDM), a 27 dB optical link budget, and a 0°C to +70°C operating temperature range, the SFPGIS90C is suited to long-reach fiber network designs requiring verified optical performance and diagnostic capabilities.\n  \u003c\/p\u003e\n\n  \u003c!-- GEO FACTS --\u003e\n  \u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003e\n    The EtherWAN SFPGIS90C is a non-hardened Gigabit Ethernet Small Form-factor Pluggable (SFP) fiber optic transceiver for long-distance single-mode network connections. EtherWAN specifies 9\/125-micron single-mode fiber, a duplex LC optical connector, a nominal wavelength of 1550 nm, and a maximum rated transmission distance of 90 km (approximately 55.9 miles). Manufacturer-listed optical output power is 0 to +5 dBm, receiver sensitivity is -27 dBm, and the nominal optical link budget is 27 dB. The module supports Digital Diagnostic Monitoring and operates from 0°C to +70°C (32°F to 158°F). EtherWAN's SFP Series documentation specifies a +3.3V power supply, SFP Multi-Source Agreement compliance, Class 1 laser safety, and RoHS compliance. Actual transmission distance depends on fiber attenuation, splices, connectors, operating margins, and compatible equipment at both ends of the link. The module uses a duplex two-fiber connection rather than a single-fiber bidirectional arrangement. Coremicro supplies professional networking equipment and accessories, including EtherWAN transceivers, for compatible networking applications.\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-SFPGIS90C.webp?v=1792996745\u0026amp;width=1000\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGIS90C.webp?v=1792996745\u0026amp;width=700 700w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGIS90C.webp?v=1792996745\u0026amp;width=1000 1000w, https:\/\/cdn.shopify.com\/s\/files\/1\/0580\/0860\/0738\/files\/EtherWan-SFPGIS90C.webp?v=1792996745\u0026amp;width=1400 1400w\" sizes=\"(min-width: 1440px) 1416px, 100vw\" width=\"1000\" height=\"1000\" alt=\"EtherWAN SFPGIS90C 90km Gigabit SFP with 1550nm duplex LC optics and DDM\" 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\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        Up to 90 km Single-Mode Fiber Reach\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The SFPGIS90C is rated for Gigabit Ethernet transmission distances up to 90 kilometers over 9\/125-micron single-mode optical fiber. This extended reach makes the module relevant for connecting compatible networking equipment across long fiber routes. Actual achievable distance depends on the installed fiber's attenuation, connector and splice losses, and the available optical power budget rather than distance alone.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        1550 nm Long-Reach Optical Transmission\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The module uses a nominal 1550 nm optical wavelength for single-mode fiber communication. This wavelength is commonly used in long-distance optical infrastructure, where fiber attenuation and link engineering are important considerations. Both ends of the connection must use compatible wavelengths, optical characteristics, data rates, and SFP host interfaces.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        Duplex LC Fiber Optic Interface\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The SFPGIS90C features a duplex LC connector for separate transmit and receive fiber paths. Unlike a single-LC BiDi transceiver, this module uses a conventional two-fiber arrangement with suitable single-mode patch cords. Installers should verify connector compatibility, fiber polarity, cable condition, and both optical endpoints before commissioning the connection.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        1 Gbps Gigabit Ethernet SFP Connectivity\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The SFPGIS90C is designed for Gigabit Ethernet operation through a compatible SFP host. Its modular transceiver form factor allows supported Ethernet switches and networking devices to establish an optical connection over long-distance fiber infrastructure. This is a 1 Gbps SFP module rather than a 10 Gigabit SFP+ transceiver, and host compatibility must be confirmed before installation.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        Digital Diagnostic Monitoring Support\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        Digital Diagnostic Monitoring (DDM) provides transceiver diagnostic functionality when supported by the connected networking equipment. Depending on the host interface, available readings can assist with checking module operating conditions and investigating optical link performance. DDM availability through the switch's management system depends on the host device and its supported monitoring features.\n      \u003c\/p\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"cm-feature-box\"\u003e\n      \u003ch3 class=\"cm-feature-box__title\"\u003e\n        27 dB Optical Link Budget\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        EtherWAN specifies optical transmit power from 0 to +5 dBm and receiver sensitivity of -27 dBm, resulting in a nominal 27 dB link budget based on the minimum transmit output. This information helps engineers evaluate the allowable optical losses of a planned fiber connection. Fiber attenuation, splices, connectors, receiver input limits, and an appropriate engineering margin must be considered when designing the complete link.\n      \u003c\/p\u003e\n
