Moxa SFP-1GSXLC-T , 1000BaseSX, 0.5 km content_copy

The Moxa SFP-1GSXLC-T is a Gigabit Ethernet SFP module designed as an extension for Moxa industrial switches. It enables connection via multimode fiber cables and is specifically designed for use in industrial environments where high operating temperatures and demanding conditions prevail. The module supports the digital diagnostics function (DDM), allowing real-time monitoring of key operating parameters such as temperature, voltage, and optical power. This function is particularly useful for maintenance and fault diagnosis in critical networks. Compliance with the IEEE 802.3z standard ensures interoperability with other Gigabit Ethernet devices. The module is hot-pluggable, meaning it can be inserted or removed from the switch without interrupting network operation. Connection is made via a duplex LC connector, which is standard for fiber cable networks. The TTL signal detection supports automatic recognition of the signal state.

Applications

The SFP-1GSXLC-T is designed for industrial applications, particularly in environments with high temperatures, such as production halls, power supply facilities, or the transportation sector. The operating temperature range of -40 to 85 °C makes it suitable for use in extended temperature ranges. It is used in networks requiring high reliability and stability, such as in automation technology or for transmitting sensor data over fiber cables. Support for multimode fibers enables flexible installations in existing fiber infrastructures.

Functions and Features in Detail

The module features a single port and is designed for operation with multimode fibers. It supports fiber types OM1, OM2, OM3, and OM4, with the range varying depending on the fiber type. With OM1 fibers, the typical range is 300 meters, with OM2 it is 550 meters, and with OM3/OM4 up to 1 kilometer. The wavelength is typically 850 nm, with the transmitter range between 830 and 860 nm and the receiver range between 770 and 860 nm. The optical power of the transmitter is between -4 and -9.5 dBm, and that of the receiver is between 0 and -18 dBm. Laser class 1 (compliant with EN 60825-1) ensures safe use without risk to the eyes. The TTL signal detection enables monitoring of the signal state.

Technology Explained Simply

The module uses SFP (Small Form-factor Pluggable) technology, which provides a compact and modular solution for network connections. The hot-pluggable feature allows the module to be inserted and removed without network downtime, which is advantageous for maintenance and configuration. The DDM function enables monitoring of operating parameters, which is helpful for diagnosing network faults. The use of multimode fibers is particularly suitable for short to medium distances, as they have a larger core diameter and are therefore easier to connect. The 850 nm wavelength is typical for multimode systems and offers a good balance between range and signal quality.

Compatibility and Accessories

The module is available as an accessory for a wide range of Moxa switches and can be used in these devices to establish network connections via fiber cables. It is compatible with multimode fibers of types OM1, OM2, OM3, and OM4. The use of LC duplex connectors is standard and enables easy integration into existing fiber infrastructures.

Installation and Mounting

Installation is performed by inserting the module into the corresponding SFP slot of a Moxa switch. Due to the hot-pluggable feature, this can be done without interrupting network operation. The LC duplex connector is connected to the fiber cable, ensuring correct alignment and locking. The TTL signal detection supports automatic recognition of the signal state, simplifying installation.

Operational Advantages

The module provides a reliable and stable network connection via multimode fiber cables, particularly suitable for industrial applications. The high operating temperature range of -40 to 85 °C enables use in demanding environments. The DDM function supports maintenance and fault diagnosis, increasing operational safety. The hot-pluggable feature simplifies maintenance and configuration, as the module can be replaced without network downtime. The use of multimode fibers offers flexibility in installation and is particularly suitable for short to medium distances.
