The Moxa SFP-1FEMLC-T is a 1-Port Fast Ethernet SFP module for industrial use, specifically developed for integration into Moxa Ethernet switches. It is a hot-pluggable module, which can be inserted or removed from the switch without interrupting network operation. The module complies with the IEEE 802.3u standard and supports digital diagnostic functions (DDM), enabling monitoring of optical performance parameters such as transmit power, receive level, and temperature. The LC duplex connector ensures a secure and standardized connection with fiber optic cables. The module is designed for use in harsh environments and features an extended operating temperature range of -40 to +85 °C, making it suitable for industrial applications in extreme climatic conditions. It is certified as Laser Class 1 according to EN 60825-1, allowing safe handling without additional protective measures.

Applications

The SFP-1FEMLC-T is designed for connecting network devices via fiber optic cables in industrial environments, such as production facilities, power supply networks, or railway systems. It enables data transmission over multi-mode fiber optic cable with a wavelength of 1310 nm. The typical range is up to 2 km, with the exact distance depending on the quality of the fiber and optical performance. Use in combination with Moxa switches enables a scalable and reliable network infrastructure.

Functions and Equipment in Detail

The module features an LC duplex connector, ensuring a precise and stable connection with fiber optic cables. The digital diagnostics (DDM) allow real-time monitoring of parameters such as transmit power (TX), receive level (RX), module temperature, and voltage. These functions support network administration in fault diagnosis and maintenance. The maximum power consumption is 1 W, ensuring energy-efficient operation. The operating temperature range of -40 to +85 °C makes the module suitable for use in outdoor environments, air conditioning systems, or machine rooms where high or low temperatures may occur.

Technology Explained Simply

The module operates in the Fast Ethernet standard (100Base-FX) and transmits data at a speed of 100 Mbit/s over fiber optic cable. The wavelength of 1310 nm is optimized for multi-mode fibers and enables good signal transmission over medium distances. The transmit power (TX) ranges from -8 to -18 dBm, which is sufficient for stable signal transmission over the specified range. The receive range (RX) is -3 to -32 dBm, ensuring high sensitivity of the receiver. The link budget of 14 dB describes the maximum difference between transmit power and receive threshold, influencing the maximum range. The dispersion penalty of 2 dB accounts for signal distortion due to chromatic dispersion in the fiber.

Compatibility and Accessories

The module is specifically developed for use in Moxa Ethernet switches and requires no additional adapters or converters. It is compatible with multi-mode fiber optic cables of types OM1, OM2, OM3, OM4, as well as 62.5/125 µm or 50/125 µm. For use in networks with high optical power, especially with single-mode models, it is recommended to use an attenuator to prevent damage to sensitive receivers. Certification according to DNV also makes the module suitable for marine applications.

Installation and Mounting

Installation is performed by simply inserting the module into the corresponding SFP slot of the Moxa switch. Due to the hot-pluggable function, no network downtime is required. Connection to the fiber optic cable is made via the LC duplex connector, ensuring a clean and correct connection to avoid signal loss. Mounting requires no special tools, as the module fits mechanically into the slot.

Operational Advantages

The module offers high reliability due to its extended temperature range and robust construction. The DDM functions enable proactive network monitoring and reduce maintenance time. Compatibility with Moxa switches and support for multi-mode fibers make it a flexible solution for industrial networks. Certifications according to EN 60825-1, UL 62368-1, IEC 62368-1, EN 55032/35, FCC Part 15B, ICES-003, and IEC 61000-4-2 to -4-11 guarantee safety, EMC compliance, and reliability in various environments. The 5-year manufacturer's warranty provides additional security for operation.
