Description
Product Overview
The EtherWAN SFP2IS20M Hardened 2.5G Single-Mode SFP Transceiver delivers high-speed optical connectivity for compatible industrial Ethernet switches and networking equipment. 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.
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. Contact Coremicro for product compatibility, availability, and purchasing information.
2.5 Gbps Optical Ethernet Connectivity
The SFP2IS20M supports a transmission speed of 2500 Mbps for compatible 2.5 Gigabit Ethernet SFP connections. 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.
Up to 20 km Single-Mode Fiber Reach
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.
1310 nm Duplex LC Optical Interface
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.
Digital Diagnostic Monitoring Support
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.
Hardened -40°C to +85°C Operation
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.
Optical Power Specifications for Link Planning
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. Network engineers should evaluate fiber attenuation, connector and splice losses, receiver input limits, and an appropriate engineering margin before deploying the transceiver over a planned fiber route.

What is the EtherWAN SFP2IS20M used for?
The EtherWAN SFP2IS20M is a hardened 2.5 Gigabit Ethernet SFP optical transceiver designed for long-distance single-mode fiber networking. It supports 2500 Mbps transmission, uses 1310 nm optics and a duplex LC connector, and provides rated fiber connectivity up to 20 km when installed with compatible host equipment.
Does SFP2IS20M support 2.5 Gigabit Ethernet?
Yes. EtherWAN lists SFP2IS20M in its 2.5G BASE SFP Series with a transmission speed of 2500 Mbps. The connected switch or networking device must support the module's data rate, optical interface, and applicable host requirements. A standard 1 Gbps SFP port does not automatically support this 2.5G module.
What fiber type and distance does SFP2IS20M support?
The SFP2IS20M supports distances up to 20 km over 9/125-micron single-mode fiber. It uses a duplex LC connector with separate transmit and receive fiber connections. Actual distance depends on fiber attenuation, connectors, splices, optical power levels, and the complete link design.
What are the optical power and receiver sensitivity specifications?
EtherWAN specifies optical transmit power from -5 to 0 dBm and receiver sensitivity of -16 dBm. These figures yield a calculated nominal optical power budget of 11 dB using minimum transmit power. The published manufacturer table does not clearly identify a separate numerical link budget. The complete connection should be evaluated against the actual fiber losses and receiver operating limits.
Does the SFP2IS20M support DDM and industrial temperatures?
Yes. The SFP2IS20M supports Digital Diagnostic Monitoring and operates from -40°C to +85°C. DDM readings may be available through compatible host equipment with transceiver monitoring support. The connected networking device and other installation components must also meet the environmental requirements of the deployment.
Which EtherWAN switches list SFP2IS20M as a compatible accessory?
EtherWAN lists SFP2IS20M among the optical transceiver accessories for its EX61900G, EX71900G, and EX78900G Ethernet switch series. Buyers should verify the exact model variant, SFP port capabilities, and supported operating data rates before installation. Compatibility with other networking equipment requires separate confirmation.
What is the difference between SFP2IS20M and SFP2IM2AM?
The SFP2IS20M is a 1310 nm single-mode fiber transceiver designed for distances up to 20 km. The SFP2IM2AM is a separate 850 nm multimode transceiver supporting shorter fiber connections, with listed distances of 160 m on OM2, 400 m on OM3, and 500 m on OM4. Both are hardened 2.5G modules with duplex LC connectors and DDM, but they use different fiber types and are not direct substitutes in every installation.
