The SFP-1GLHXLC-T from Moxa is a 1-Port Gigabit Ethernet SFP module for use in Moxa Ethernet switches. It serves as a hot-pluggable transceiver for establishing fiber optic connections with a transmission range of up to 40 km over single-mode fiber. The module is specifically designed for industrial applications requiring high reliability and operational safety under harsh environmental conditions.

Applications

The module is suitable for use in industrial networks, particularly in environments with high mechanical, thermal, or electromagnetic stress. Typical application scenarios include networking of production facilities, power supply networks, transportation systems, or in the maritime sector. The high range of 40 km enables connections over long distances, for example between locations within a factory complex or between remote telemetry stations.

Functions and Features in Detail

The module supports Gigabit Ethernet transmission according to the IEEE 802.3z standard. It is equipped with an LC duplex connector, ensuring a secure and stable optical connection. The digital diagnostics (DDM) enables real-time monitoring of transceiver performance, including optical power, temperature, and operating voltage. This supports network maintenance and fault diagnosis. The laser class 1 according to EN 60825-1 ensures safe handling without risk to the eyes.

Technology Explained Simply

The module operates in single-mode mode with a wavelength of 1310 nm. The maximum range of 40 km is achieved through the combination of high output power (TX power +5 to -9.5 dBm) and high sensitivity (RX sensitivity down to -33 dBm). The link budget of up to 31 dB enables a robust connection, even with low signal losses in the cable. The dispersion penalty of 1 to 5 dB accounts for signal distortion over long distances. The module consumes a maximum of 1 W power, ensuring efficient energy use.

Compatibility and Accessories

The module is specifically developed for use in Moxa Ethernet switches. It is not intended for general SFP ports from other manufacturers, although the physical form factor standardization (SFP) suggests possible compatibility. WDM modules (e.g. SFP-10A/B, SFP-20A/B, SFP-40A/B) can be used in pairs to realize two unidirectional connections over a single fiber optic cable. The TX/RX wavelengths are 1310/1550 nm or 1550/1310 nm depending on the model.

Installation and Mounting

The module is designed as a hot-pluggable module, meaning it can be inserted into or removed from the SFP slot without shutting down the switch. Installation is done by simply inserting it into the corresponding port of the switch. Connection to the fiber optic cable is made via the LC duplex connector. No additional tools or configurations are required.

Operational Advantages

The module features a wide operating temperature range of -40 to 85 °C, making it suitable for use in extreme environments. The storage temperature is also between -40 and 85 °C. Humidity levels of 5 to 95 % (non-condensing) allow use in humid or dry environments. Certifications according to EN 55032/35, FCC Part 15B, ICES-003 and IEC 61000-4-2 to -4-11 guarantee high immunity against electromagnetic interference. The maritime approval (DNV) extends the application range to ships and offshore installations. The 5-year warranty underscores the product's reliability.

Scope of Delivery

The scope of delivery includes 1x SFP-1G module and 1x warranty card.
