The Moxa SFP-1GSXLC is an industrial-grade, hot-pluggable 1-port Gigabit Ethernet SFP module, specifically designed for use in Moxa Ethernet switches. It enables transmission over fiber optic cables and supports the multi-mode standard with a wavelength of 850 nm. The module is designed for a range of up to 0.5 km, with the maximum distance achievable under specific conditions such as the use of certified fiber optic cables (OM1/OM2). The connection is made via an LC duplex connector, suitable for most industrial applications. The module is IEEE 802.3z-compliant and features a digital diagnostics function (DDM), enabling monitoring of optical performance. It includes LVPECL differential signals and TTL signal detection, enhancing the reliability of data transmission. Laser class 1 ensures safe operation without risk to the human eye.

Applications

The SFP-1GSXLC is designed for use in industrial networks where stable and reliable data transmission over fiber optic cables is required. It is particularly suitable for applications in automation technology, power supply, transportation, and other environments with high demands on operational safety. The module form factor allows for easy integration into existing Moxa switch systems, with the hot-pluggable feature enabling maintenance-friendly installation and replacement without interrupting network operation.

Functions and Features in Detail

The module offers a digital diagnostics function (DDM), enabling real-time monitoring of parameters such as optical power, temperature, and voltage. This supports network administration in the early detection of faults. TTL signal detection ensures the module correctly detects the connection status and relays it to the switch. The use of LVPECL differential signals provides robust signal transmission, offering better resistance to interference and noise. Laser class 1 guarantees safe operation, even in environments with direct access to optical components.

Technology Explained Simply

The SFP-1GSXLC uses multi-mode technology with a wavelength of 850 nm, optimized for short to medium distances. The maximum range is 0.5 km, with the actual distance depending on the quality of the fiber optic cable used. The optical power of the transmitter (TX) is in the range of +5 to -9.5 dBm, while the receiver (RX) can process signals in the range of 0 to -33 dBm. The link budget is up to 31 dB, describing the maximum attenuation the signal can overcome without breaking the connection. The dispersion penalty of up to 5 dB accounts for signal distortion due to chromatic dispersion, which can occur over longer distances.

Compatibility and Accessories

The module is specifically developed for use in Moxa Ethernet switches and requires no additional adapters or converters. It is part of the SFP-1G series, which offers various transceiver types for different transmission conditions, including single-mode and WDM modules. The use of WDM modules requires paired operation, where a transmitter and a receiver module work together.

Installation and Mounting

Installation is performed by simply inserting the module into the corresponding SFP slot of the switch. The hot-pluggable feature allows for replacement without interrupting network operation, provided the switch supports it. Mounting requires no special tools or additional components. Connection to the fiber optic cable is made via the integrated LC duplex connector, ensuring a secure and stable connection.

Operational Advantages

The SFP-1GSXLC offers high operational safety through laser class 1 and the integrated DDM function, enabling proactive network monitoring. The hot-pluggable feature reduces downtime during maintenance. The use of LVPECL signals and TTL signal detection ensures robust and reliable data transmission. The maximum range of 0.5 km is sufficient for many industrial applications, particularly in factories, power plants, or transportation systems, where cabling occurs over short to medium distances. The operating temperature of the standard model ranges from 0 to 60 °C, with T-models available for the extended range of -40 to 85 °C, expanding usability in harsh environments.

Certifications and Safety

The module complies with safety standards UL 62368-1, IEC 62368-1, and EN 60825-1, ensuring electrical and optical safety. EMI/EMC certifications according to EN 55032/35, FCC Part 15B, and ICES-003 ensure electromagnetic compatibility. EMS certification according to the IEC 61000-4-x series guarantees immunity to electromagnetic interference. Additionally, the module is certified for use in marine applications according to DNV. The manufacturer's warranty is 5 years.
