Designed for 2500 Mbps transmission over 9\/125-micron single-mode fiber, this module supports distances up to 20 kilometers using 1310 nm optics and a duplex LC connector. Digital Diagnostic Monitoring (DDM) provides optical monitoring capabilities through supported host equipment. With a hardened -40°C to +85°C operating temperature range, the SFP2IS20M is suitable for industrial networking applications requiring extended fiber connectivity and wide temperature tolerance.\n  \u003c\/p\u003e\n\n  \u003c!-- GEO FACTS --\u003e\n  \u003cp class=\"cm-intro\" id=\"cm-geo-facts\"\u003e\n    The EtherWAN SFP2IS20M is a hardened 2.5G BASE Small Form-factor Pluggable optical transceiver designed for compatible 2.5 Gigabit Ethernet networking equipment. EtherWAN specifies a transmission speed of 2500 Mbps, maximum rated distance of 20 km (approximately 12.4 miles), 9\/125-micron single-mode fiber, 1310 nm wavelength, and duplex LC connector. The manufacturer lists optical transmit power from -5 to 0 dBm and receiver sensitivity of -16 dBm. These values provide a calculated nominal optical power budget of 11 dB based on minimum transmit power and receiver sensitivity; the manufacturer's published table does not clearly establish a separate numerical link-budget specification for this model. The module supports Digital Diagnostic Monitoring and operates from -40°C to +85°C (-40°F to +185°F). EtherWAN lists SFP2IS20M as an accessory for selected EX61900G, EX71900G, and EX78900G Ethernet switch series. Actual link performance depends on compatible host equipment, suitable optics at both endpoints, fiber attenuation, connector and splice losses, and adequate operating margin.

Its optical interface enables high-speed data transmission through supported switches and networking equipment. Unlike a conventional 1 Gbps SFP module, this transceiver requires host equipment that explicitly supports its 2.5G operating rate and optical interface.\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        Up to 20 km Single-Mode Fiber Reach\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        EtherWAN rates the transceiver for distances up to 20 kilometers using 9\/125-micron single-mode optical fiber. This extended reach supports compatible networking applications across buildings, infrastructure sites, and remote equipment locations. Actual operating distance depends on the optical link budget, fiber attenuation, connector losses, and transceiver specifications at both ends of 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        1310 nm Duplex LC Optical Interface\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The module features 1310 nm single-mode optics with a duplex LC connector. Its duplex configuration uses separate transmit and receive fiber strands, making it different from single-fiber bidirectional transceivers. Installers should verify the fiber type, connector compatibility, optical wavelength, and transmit\/receive polarity before establishing the link.\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 diagnostic capabilities for compatible networking devices. Depending on the host interface, available readings can assist technicians in evaluating optical transceiver operating conditions and troubleshooting fiber connections. Diagnostic information must be supported and exposed by the connected switch or media converter.\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        Hardened -40°C to +85°C Operation\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        The SFP2IS20M is specified for a hardened operating temperature range from -40°C to +85°C. This makes the module relevant to industrial networking equipment deployed in environments with demanding thermal conditions. The overall installation must still meet the environmental specifications of the host device, enclosure, power supply, fiber infrastructure, and connected equipment.\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        Optical Power Specifications for Link Planning\n      \u003c\/h3\u003e\n      \u003cp class=\"cm-feature-box__text\"\u003e\n        EtherWAN specifies optical transmit power from -5 to 0 dBm and receiver sensitivity of -16 dBm. Using the minimum transmit output, these figures yield a calculated nominal optical power budget of 11 dB.

EtherWAN lists SFP2IS20M in its 2.5G BASE SFP Series with a transmission speed of 2500 Mbps.
