SFPGIS20M Hardened Gigabit Single-Mode SFP Module, 20km

SFPGIS20M Hardened Single-Mode Fiber Transceiver, 20km

Gigabit SFP module with duplex LC connectors, 1310nm optics, and digital diagnostic monitoring. Reach up to 20km over single-mode fiber. Hardened operating temperature: −40 to 85°C (−40 to 185°F).

The EtherWAN SFPGIS20M provides 1 Gbps single-mode fiber connectivity for compatible Ethernet switches and media converters. Its hardened temperature rating makes it suitable for industrial equipment, transportation systems, utility networks, and other installations exposed to wide temperature changes.

The module uses two 9/125µm single-mode fiber strands through a duplex LC connection. It supports links up to 20km, subject to the link’s optical losses. Confirm your equipment’s supported SFP specifications, installed fiber type, and required distance before ordering.

Key Features

• Gigabit connectivity: Supports 1 Gbps Ethernet fiber links on compatible equipment.
• Single-mode fiber support: Designed for 9/125µm single-mode fiber.
• Up to 20km reach: Supports longer-distance fiber connections, subject to optical losses from the fiber, connectors, and splices.
• Duplex LC connection: Uses separate transmit and receive fiber strands.
• 1310nm optics: For connections with a compatible transceiver at the other end.
• Digital diagnostic monitoring: Includes DDM for supported monitoring functions on compatible equipment.
• Hardened operation: Rated from −40 to 85°C (−40 to 185°F).
• MSA compliant: Follows the Small Form Factor Pluggable Multi-Sourcing Agreement.

Applications

• Gigabit fiber uplinks between compatible industrial Ethernet switches.
• Single-mode connections between buildings or remote equipment locations.
• Fiber connections using compatible hardened media converters.
• Transportation, utility, and surveillance networks requiring longer-distance connectivity across a wide temperature range.

Common Questions

Will this module work over any distance up to 20km?
The maximum specified reach is 20km, but distance alone does not determine compatibility. Fiber, connectors, and splices contribute optical losses, and the receiving transceiver’s input limits must also be considered. Confirm the optical specifications at both ends when planning the link.

What fiber cable does this module require?
It requires two strands of 9/125µm single-mode fiber with duplex LC connectors at the module. Use an LC-to-LC patch cable for an LC connection at the other end, or an SC-to-LC patch cable when connecting to an SC patch panel or compatible SC-equipped device.

Will this work in any switch or media converter with an SFP port?
Check your equipment’s supported transceiver specifications. Its port must support a compatible 1 Gbps single-mode SFP, and the manufacturer may have additional compatibility requirements. This module requires a compatible optical transceiver at the other end. Contact us with your equipment model, fiber type, and link distance if you need help selecting a module.
