The SFP-1GEZXLC from Moxa is a 1-Port Gigabit Ethernet SFP module, specifically developed as an extension for Moxa Ethernet switches in industrial networks. It enables wireless data transmission over single-mode fiber optic cables and supports a range of up to 110 km. The module is designed for use in demanding environments where high reliability and long operating times are required. It supports hot-plug functionality, allowing the module to be inserted or removed from the switch during operation without interrupting network performance. Digital diagnostic monitoring (DDM) enables real-time monitoring of optical parameters such as transmit power, receiver sensitivity, and temperature, simplifying network diagnostics and maintenance.

Applications
This module is suitable for industrial applications such as automation systems, power supply, transportation, and maritime infrastructure, where stable and long fiber optic connections are required. The high range of 110 km makes it particularly suitable for connecting sites over long distances, such as between factories, terminals, or district heating networks. The T-models with an operating temperature range of -40 to +85 °C extend its use in extreme climatic conditions, for example in the oil and gas industry or in arctic regions.

Functions and Features in Detail
The SFP-1GEZXLC uses LVPECL differential signals and TTL signal detection to ensure reliable signal transmission over fiber optic cables. The connector interface is via a duplex LC connector, which is standard for SFP modules. The optical transmit power ranges from -9.5 to +5 dBm, while the receiver sensitivity reaches up to -33 dBm. This value enables a stable connection even at low signal strength. The link budget of 8.5 to 31 dB and dispersion penalty of 1 to 5 dB are optimized for transmission over long distances. When high optical power levels are used, the use of attenuators is recommended to avoid signal overload.

Technology Explained Simply
The module operates according to the Gigabit Ethernet standard (1000BASE-ZX) and uses single-mode fiber, which is optimized for long transmission distances. The wavelength is 1550 nm, ensuring maximum range and low attenuation in fiber optic cables. The DDM function allows monitoring of operating parameters, enabling potential faults to be detected early. Hot-plug functionality reduces downtime, as the module can be replaced without interrupting network operations. Power is supplied through the switch system, with the module consuming a maximum of 1 W.

Compatibility and Accessories
The module is intended as an accessory for Moxa Ethernet switches and can be combined with other SFP modules from the SFP-1G series to support various ranges and fiber types. It is part of the SFP-1G series, which also includes WDM pairs (Wavelength Division Multiplexing), enabling multiple signals to be transmitted over a single fiber optic cable. Compatibility with single-mode fibers and support for industrial temperature ranges make it a flexible component in industrial networks.

Installation and Mounting
Installation is performed by inserting the module into a free SFP slot on the Moxa switch. Hot-plug functionality allows replacement without interrupting network operations. Cabling is done via a duplex LC fiber optic cable connected to the module. Correct alignment of the LC connector is important to ensure a stable connection. Installation requires no additional tools or software configurations — the module is automatically detected and initialized.

Operational Advantages
The high range of 110 km reduces the need for intermediate amplifiers or additional switches, simplifying network architecture and lowering operating costs. The DDM function enables proactive maintenance, as deviations in signal quality can be detected early. Industrial temperature resistance and certifications according to UL 62368-1, IEC 62368-1, and IEC 60825-1 guarantee safety and reliability in operation. The 5-year warranty underscores the product’s quality and durability.

Certifications and Environmental Conditions
The module complies with safety standards UL 62368-1, IEC 62368-1, and IEC 60825-1. It is also certified for use in marine environments according to DNV. EMC requirements according to EN 55032/35, FCC Part 15B, and ICES-003, as well as immunity to interference according to IEC 61000-4-2 to -4-11, ensure reliable operation in electromagnetically noisy environments. The operating temperature is 0–60 °C (standard) or -40–85 °C (T-models), with storage temperature also ranging from -40 to +85 °C. Humidity is 5–95 %, non-condensing.

Scope of Delivery
The product is delivered with one SFP-1G Series module and a warranty card.
