The Moxa SFP-1G40ALC-T is a 1-Port Gigabit Ethernet SFP module of the SFP-1G series, serving as an optional expansion for various Moxa Ethernet switches. It enables connection via single-mode fibre with a transmission range of 40 km at a wavelength of 1310 nm. The module is designed for use in industrial networks, where high reliability and operational safety under demanding conditions are required. It supports digital diagnostic functions (DDM), enabling continuous monitoring of parameters such as transmit power, receiver sensitivity, and temperature. The hot-plug functionality allows the module to be inserted and removed during operation without interrupting network service.

Applications

The module is suitable for applications in industrial automation, transportation, energy supply, and maritime sectors, where stable, long-distance fibre communication is required. The T-model variant is specifically designed for extreme operating environments, with an operating temperature range of -40 to 85 °C. This makes it suitable for outdoor use, in climatically challenging industrial facilities, or in vehicles. Certification as a Class-1 laser product according to IEC 60825-1 ensures safe handling without risk to the eyes.

Features and Equipment in Detail

The module features an LC duplex connector, standard for single-mode connections. The digital diagnostics (DDM) enable remote monitoring of operational parameters, simplifying network maintenance and fault diagnosis. Support for differential LVPECL signals and TTL detection ensures a compatible and stable interface with switches. Maximum power consumption is 1 W, ensuring energy-efficient operation.

Technology Explained Simply

Transmission occurs over single-mode fibre at a wavelength of 1310 nm, enabling high bandwidth and low attenuation over long distances. The range of 40 km is suitable for industrial applications such as connecting production sites over large distances or communication between locations within a corporate network. The receiver sensitivity is up to -33 dBm, ensuring high sensitivity to weak signals. The link budget of 8.5 to 31 dB allows flexible adaptation to different fibre cable qualities and attenuations. The dispersion penalty of 1–5 dB accounts for signal distortion over long distances.

Compatibility and Accessories

The module is specifically developed for use with Moxa Ethernet switches that feature SFP slots. It is part of the SFP-1G series, which also includes variants for multi-mode and WDM fibres. For use with SFP-LHX, ZX, EZX, EZX-120, and WDM types, the manufacturer specifies that an attenuator is required to ensure signal quality.

Installation and Mounting

Installation is performed by simply inserting the module into the SFP slot of the switch. The hot-plug functionality allows installation without network downtime. Mechanical mounting requires no additional tools. Connection to the fibre cable is made via the integrated LC duplex connector.

Operational Advantages

The module offers high reliability due to its robust construction and wide operating temperature range. Digital diagnostics enable proactive maintenance and reduce downtime. Energy efficiency, with a maximum consumption of 1 W, is advantageous in extensive networks. Certifications according to UL 62368-1, IEC 62368-1, EN 55032/35, FCC Part 15B, ICES-003, and IEC 61000-4-2 to -4-11 guarantee compliance with international safety and EMC standards.
