The Moxa SFP-1GLSXLC-T is a 1-Port Gigabit Ethernet SFP module serving as an optional expansion for industrial Moxa Ethernet switches. It enables connection via fiber optic cables and supports the 1000Base SX+ technology with a wavelength of 1310 nm. The module is designed for use in industrial environments where high reliability and operational safety are required. It features an LC-Duplex connector and is designed for a maximum transmission range of up to 2 km, with the actual range depending on the type of fiber optic cable used (e.g. OM1, OM2) and cable losses. Compatibility with selected cable manufacturers is required for full range.

Applications
This module is suitable for industrial networks requiring stable, long-range connections over fiber optic cables. Typical applications include factories, power supply networks, transportation infrastructure, or marine applications, where the extended operating temperature range of -40 to 85 °C (T-model) ensures reliable operation under extreme environmental conditions. High compatibility with various fiber optic cable types and support for IEEE 802.3z enable flexible integration into existing networks.

Functions and Features in Detail
The SFP-1GLSXLC-T supports the hot-plug function, allowing the module to be inserted or removed from the switch without interrupting network operation. The integrated digital diagnostic monitoring (DDM) enables real-time monitoring of optical parameters such as transmit power, receive level, and temperature, simplifying network diagnostics and maintenance. The differential LVPECL inputs and outputs ensure robust signal transmission, while the TTL signal detection indicator visually displays the signal status.

Technology Explained Simply
The module uses single-mode fiber optic cable with a wavelength of 1310 nm, enabling higher transmission distances and lower signal losses compared to multi-mode fibers. The transmit power (TX) ranges from +5 to -9.5 dBm, with the exact output power depending on the model. The receive sensitivity (RX) is up to -33 dBm, ensuring high receiver sensitivity for weak signals. The link budget for this module is 18 dB, determining the maximum distance considering cable losses and dispersion. The dispersion penalty of 1 to 5 dB accounts for signal distortion over long distances. For models with higher range such as SFP-LHX, ZX, EZX, and EZX-120, the use of an attenuator is recommended to optimize signal quality.

Compatibility and Accessories
The module is compatible with a wide range of industrial Moxa Ethernet switches that support SFP ports. The use of LC-Duplex connectors ensures a standardized and secure connection. Specific fiber optic cables are required for the maximum range of 2 km, which are listed in the compatibility list on moxa.com. The modules are designed for use in industrial networks and comply with the safety requirements of Laser Class 1 according to EN 60825-1.

Installation and Mounting
Installation is performed by simply inserting the module into the corresponding SFP port of the switch. The hot-plug function allows installation without network interruption. Correct alignment of the LC connector is important to ensure a stable connection. Mounting requires no additional tools or components.

Operational Advantages
The module offers high operational reliability due to the extended temperature range and robust construction. The digital diagnostic monitoring (DDM) enables proactive network monitoring and reduces maintenance time. High compatibility with various fiber optic cables and switch models increases flexibility in network planning. The 5-year warranty underscores the product's reliability.

Certifications and Safety
The module complies with safety requirements according to UL 62368-1, IEC 62368-1, and EN 60825-1. It is also certified for use in marine environments according to DNV. EMI and EMS certifications (EN 55032, FCC Part 15B, ICES-003, IEC 61000-4-2 to 4-11) ensure safe and interference-free operation in electromagnetically demanding environments.
