The SFP-1GZXLC-T from Moxa is an industrial-grade 1-port Gigabit Ethernet SFP module that enables fiber optic connectivity. It is specifically designed for integration into Moxa switches and offers hot-pluggable functionality, allowing for easy and uninterrupted installation and replacement of modules. The module is IEEE 802.3z-compliant and supports the 1000BaseZX standard, designed for long-distance transmission over single-mode fiber. The operating temperature ranges from -40 to 85 °C, making it suitable for demanding industrial environments. The module has a compact form factor designed for use in standard SFP slots.

Applications
This module is designed for industrial networking applications requiring reliable and long-range fiber optic connections. Typical use cases include networking of production facilities, power supply networks, transportation systems, or surveillance systems, where stable and interference-resistant connections over long distances are required. Its high temperature resistance also makes it suitable for outdoor use or machine rooms with extreme heat or cold exposure.

Features and Specifications in Detail
The module features a duplex LC connector, enabling connection to standard fiber optic cables. It supports Digital Diagnostic Monitoring (DDM), allowing real-time data on optical performance, temperature, voltage, and other parameters to be retrieved. This facilitates network monitoring and fault diagnosis. Additionally, it offers TTL signal detection (RX loss), indicating the reception status, as well as a differential LVPECL output, which can be used for integration into specific control systems. The module is classified as a Class-1 laser product according to EN 60825-1, ensuring safe handling.

Technology Explained Simply
The 1000BaseZX technology enables data transmission at a speed of 1 Gigabit per second over single-mode fiber. The typical range is 80 km, making it suitable for long-distance connections between sites. The wavelength is typically 1550 nm, with the transmitter range between 1530 and 1565 nm and the receiver range between 1500 and 1610 nm. The optical output power (TX) is -1 to -9 dBm, and the receiver sensitivity (RX) is -1 to -19 dBm. These values ensure stable signal transmission over the specified distance.

Compatibility and Accessories
The module is designed for use with Moxa switches that feature SFP slots. It is not specifically designed for other manufacturers, but it can be used in compatible devices with SFP standard interfaces, provided the electrical and optical specifications match.

Installation and Mounting
Installation is performed by simply inserting the module into an SFP slot on the switch. The hot-pluggable functionality allows for replacement without powering down the device. Connection to the fiber optic cable is made via the integrated duplex LC connector. No additional tools or configurations are required, as the module is plug-and-play.

Operational Advantages
The high range of up to 80 km over single-mode fiber enables networking over long distances without additional amplifiers. The operating temperature range of -40 to 85 °C ensures stable performance in extreme environments. The DDM function supports network monitoring and enables fast fault detection. The integrated TTL signal detection and LVPECL output provide additional connection options for control systems. The 5-year warranty underscores the product's reliability.
