The Moxa SFP-1GEZXLC-120 is an industrial-grade SFP module for Gigabit Ethernet transmission over single-mode fiber optic cable. It is designed to extend network connections over long distances and is specifically engineered for demanding environments such as factories, power supply networks, or marine applications. The module supports a maximum transmission distance of 120 km and operates at a wavelength of 1550 nm, making it suitable for high-performance applications with low attenuation. It is fully IEEE 802.3z-compliant and enables bidirectional data transmission over a single fiber optic cable. The connection is made via an LC duplex connector, ensuring a secure and stable mechanical connection. The module is hot-pluggable, meaning it can be inserted or removed from a compatible switch without interrupting network operation.

Applications

The SFP-1GEZXLC-120 is designed for industrial networks requiring high reliability and long transmission distances. Typical use cases include networking of remote control systems, industrial automation systems, monitoring networks, or marine communication systems. The high operating temperature range of -40 °C to +85 °C makes it suitable for extreme climatic conditions, such as those encountered in outdoor installations or machine rooms. Certification according to DNV ensures its use in marine applications.

Features and Specifications in Detail

The module includes digital diagnostic monitoring (DDM), which allows real-time monitoring of optical parameters such as transmit power, receive sensitivity, temperature, and voltage. This supports network administrators in fault diagnosis and maintenance. The laser class 1 (EN 60825-1) ensures safe operation without risk to the human eye. The maximum power consumption is 1 W, which contributes to energy efficiency in industrial operation. The operating temperature ranges include standard conditions (0 to 60 °C) as well as extended T-models (-40 to 85 °C), with the SFP-1GEZXLC-120 being designed as a T-model.

Technology Explained Simply

Transmission occurs over single-mode fiber (type G.652), optimized for long distances. The wavelength of 1550 nm provides low attenuation in fiber optic cable, enabling the maximum reach of 120 km. The transmit power (TX Power) ranges between +3 and -2 dBm, and the receive sensitivity (RX Sensitivity) ranges between -8 and -33 dBm. These values ensure stable and error-free data transmission over the entire distance. The module is designed for use in switches and other network devices that support SFP ports.

Compatibility and Accessories

The module is compatible with a wide range of Moxa switches that support SFP ports. It can be integrated into existing network infrastructures to extend reach or enable fiber optic networking. The model designation SFP-1GEZXLC-120 refers to the specific configuration with 1550 nm wavelength and 120 km reach.

Installation and Mounting

Installation is performed by simply inserting the module into an SFP port of a compatible switch. Due to its hot-plug capability, this can be done without powering down the device. The mechanical connection is made via the LC duplex connector, ensuring a secure and tight connection. Mounting requires no special tools or additional components.

Operational Advantages

The combination of long reach, industrial robustness, and DDM functionality provides a reliable network connection in demanding environments. Real-time diagnostics enable fast fault detection and resolution. The high operating temperature range and marine application certification significantly expand the range of applications. Energy efficiency and hot-plug capability reduce maintenance effort and increase operational safety.

Scope of Delivery

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