The Moxa SFP-1GLSXLC is a Gigabit Ethernet SFP transceiver module designed as an optional extension for industrial Moxa Ethernet switches. It enables connection via fiber optic cables and is designed for use in demanding industrial environments. The module supports hot-pluggable functionality, allowing it to be inserted or removed from a compatible switch without interrupting operation. It is equipped with an LC duplex connector and operates in multi-mode mode with a wavelength of 1310 nm. The range is up to 2 km with OM1 to OM4 fiber optic cables, with the actual range for OM1/OM2 cables depending on the fiber cable manufacturer. The module complies with the IEEE 802.3z standard and offers digital diagnostics (DDM), enabling monitoring of optical performance characteristics such as transmit power and receive sensitivity.

Applications

The SFP-1GLSXLC is suitable for industrial networking applications requiring a reliable fiber optic connection over medium distances. It is used in environments subject to high mechanical stress, temperature fluctuations, or electromagnetic interference, such as in manufacturing, energy supply, or rail transport. The standard version is designed for operating temperatures from 0 to 60 °C, while the T-models (as shown here) are designed for extreme temperatures from -40 to 85 °C. Storage is also within the range of -40 to 85 °C, with humidity levels between 5 and 95 % (non-condensing) permitted.

Functions and Equipment in Detail

The module features a single Gigabit Ethernet port and is equipped with an LC duplex connector suitable for connection to standard multi-mode fiber optic cables. Digital diagnostics (DDM) enable monitoring of parameters such as TX power range (+5 to -9.5 dBm, model-dependent), RX sensitivity (-18 to -33 dBm), and link budget (8.5 to 31 dB). The dispersion penalty is 1 to 5 dB. The maximum power consumption of the module is 1 W. Laser class 1 according to EN 60825-1 ensures safe operation without risk to the human eye.

Technology Explained Simply

The SFP-1GLSXLC uses multi-mode technology with a wavelength of 1310 nm, optimized for medium transmission distances. The use of LC duplex connectors enables a compact and secure connection with fiber optic cables. Hot-pluggable functionality allows the module to be replaced without network interruption, which is advantageous for operation in running production environments. Digital diagnostics (DDM) provide real-time data on optical performance, useful for maintenance and fault diagnosis. The operating temperature range of -40 to 85 °C makes the module suitable for locations exposed to extreme climatic conditions.

Compatibility and Accessories

The module is intended as an extension for various industrial Moxa Ethernet switches. It is equipped with LC duplex connectors and is compatible with multi-mode fiber optic cables of categories OM1 to OM4. WDM models (such as SFP-10A/B, SFP-20A/B, SFP-40A/B) are only usable in pairs and use wavelength combinations such as TX 1310/RX 1550 or TX 1550/RX 1310. The use of attenuators is recommended for models with higher ranges (SFP-LHX, ZX, EZX, EZX-120) but is not required for the SFP-1GLSXLC.

Installation and Mounting

Installation is performed by inserting the module into an SFP slot of a compatible Moxa switch. Due to hot-pluggable functionality, this can be done without switching off the switch. Connection to the fiber optic cable is made via the LC duplex connector. Correct alignment and locking of the connector must be ensured to guarantee a stable connection. Mounting requires no additional tools or components.

Operational Advantages

The SFP-1GLSXLC offers a reliable fiber optic connection with a range up to 2 km, sufficient for many industrial applications. Hot-pluggable functionality enables flexible and uninterrupted maintenance. Digital diagnostics (DDM) support network monitoring and fault localization. The high operating temperature range of -40 to 85 °C makes the module suitable for locations exposed to extreme climatic conditions. Certifications according to UL 62368-1, IEC 62368-1, EN 55032/35, FCC 15B, ICES-003, and IEC 61000-4-2 to -4-11, as well as maritime certification DNV, ensure compliance with industrial safety and EMC standards. The 5-year manufacturer's warranty provides additional security for operation.
