The SFP-1FESLC-T from Moxa is a 1-port Fast Ethernet SFP module, specifically developed for industrial fiber optic networks. It enables reliable data transmission over single-mode fiber with a range of up to 40 km. The module is designed for use in demanding environments where high stability and long-term availability are required. It is compatible with a wide range of Moxa Ethernet switches and supports the expansion of existing networks without interrupting operations.

Applications
This module is suitable for industrial applications requiring a stable fiber optic connection over long distances, such as in automation technology, power supply, or rail transport. The high operating temperature range of -40 to 85 °C makes it suitable for outdoor use or in climatically extreme environments. Certification according to DNV also enables its use in marine applications.

Functions and Features in Detail
The SFP-1FESLC-T supports the IEEE 802.3u standard for Fast Ethernet and is equipped with an LC duplex connector, ensuring a secure mechanical connection to the fiber optic cable. It features digital diagnostic functions (DDM), allowing real-time monitoring of optical parameters such as transmit power, receiver sensitivity, and temperature. This supports network administration in fault diagnosis and maintenance. A TTL signal detect indicator visually indicates the connection status.

Technology Explained Simply
The module uses single-mode fiber (type G.652) with a wavelength of 1310 nm, enabling high bandwidth and low attenuation over long distances. Typical transmit power ranges from 0 to -5 dBm, and the receiver sensitivity is -3 to -34 dBm. The link budget of 29 dB ensures sufficient signal reserve to prevent connection drops. Differential PECL inputs and outputs provide a robust electrical interface. The module is classified as a Class-1 laser product according to EN 60825-1, allowing safe use even in public areas.

Compatibility and Accessories
The module is designed for use with Moxa Ethernet switches and can be installed hot-plug without interrupting network operations. For use with single-mode fibers over 40 km range (model SFP-L), an attenuator is recommended to prevent damage from excessive optical power. Use with multimode fibers (SFP-M) is not intended for this model.

Installation and Mounting
Installation is done by simply inserting the module into an SFP slot of a compatible switch. The hot-plug capability allows installation without network interruption. The mechanical connection is made via the LC duplex connector, which is attached to the fiber optic cable. Proper alignment and cleaning of the fiber end faces are crucial for a stable connection.

Operational Advantages
The combination of high range, robust design, and integrated diagnostic functions (DDM) reduces maintenance requirements and enhances network security. The operating temperature range of -40 to 85 °C allows use in a wide variety of environments without requiring additional cooling or heating. The 5-year manufacturer's warranty underscores the product's reliability.

Certifications and Environmental Conditions
The module complies with safety requirements according to UL 62368-1 and IEC 62368-1. It is certified for use in environments with electromagnetic compatibility (EMC) according to EN 55032/35, FCC Part 15B, and ICES-003, as well as for electromagnetic immunity (EMS) according to IEC 61000-4-2 to -4-11. Operating humidity may range from 5 to 95 % (non-condensing). Maximum power consumption is 1 W.

Scope of Delivery
The product is delivered with an SFP-1FE module and a warranty card.
