The Moxa SFP-1G10ALC-T is a Hot-Pluggable transceiver module for Gigabit Ethernet connections, specifically developed as optional accessory for Moxa Ethernet switches. It enables connection via single-mode fibre with a wavelength of 1310 nm and a range of up to 10 km. The module is designed for use in industrial environments, particularly in applications requiring high operating temperatures, as it supports the extended temperature class T, covering operating temperatures from -40 to 85 °C. Compliance with the IEEE 802.3z standard ensures interoperability with standard Gigabit Ethernet networks. The module is certified as laser class 1, allowing safe use without additional protective measures.

Applications

The SFP-1G10ALC-T is designed for industrial networking applications where reliable, long-range connectivity over fibre optic cables is required. Typical use cases include networking machines in production facilities, connecting control systems in power supply applications, or communication in transportation systems. The high temperature resistance makes it particularly suitable for outdoor installations, machine rooms, or environments with significant temperature fluctuations.

Features and Equipment in Detail

The module features an LC duplex connector, designed for connection with standard single-mode fibre optic cables. It supports digital diagnostic functions (DDM), enabling real-time monitoring of parameters such as transmit power, receiver sensitivity, and temperature. The TTL signal detection ensures the module correctly indicates the connection status. The LVPECL differential signals ensure robust and interference-resistant data transmission, which is crucial for industrial environments.

Technology Explained Simply

The transceiver operates at a wavelength of 1310 nm, optimised for single-mode fibre, enabling a range of up to 10 km. The TX power is in the range of -9.5 to +5 dBm, with the exact output power being model-dependent. The receiver sensitivity is up to -33 dBm, ensuring high reception efficiency even with weak signals. The link budget of up to 31 dB allows flexible use under various conditions. The dispersion penalty of 1–5 dB accounts for signal distortion over distance, which is important for network planning.

Compatibility and Accessories

The module is designed as a Hot-Pluggable module, meaning it can be inserted into a compatible Moxa switch without interrupting network operation. It is specifically developed for Moxa Ethernet switches that support SFP ports. Compatibility with other manufacturers is not guaranteed. The use of an optical attenuator is recommended for models with higher ranges to optimise signal quality.

Installation and Mounting

Installation is performed by simply inserting the module into the SFP port of the switch. The TTL signal detection ensures the switch recognises the module’s status and activates the connection accordingly. No additional tools or configurations are required. The Hot-Pluggable feature enables quick and secure replacement without network interruption.

Operational Advantages

The module offers high reliability due to its robust construction and DDM support, enabling proactive monitoring of the network connection. The extended temperature class T ensures stable operation even in extreme environments. The 5-year manufacturer’s warranty underscores the product’s quality and durability. Energy efficiency with a maximum power consumption of 1 W reduces operating costs.

Certifications and Safety

The module complies with safety standards UL 62368-1, IEC 62368-1, and EN 60825-1 (laser class 1). It is also certified for EMI/EMC (EN 55032/35, FCC Part 15B, ICES-003) and EMS (IEC 61000-4-2 to -4-11). Certification by DNV makes it suitable for marine applications as well.

Scope of Delivery

The product is delivered with one SFP-1G module and a warranty card.

Operating Environments

The module can be operated at temperatures from -40 to 85 °C and humidity levels from 5 to 95 % (non-condensing). The storage temperature is also in the range of -40 to 85 °C.

Warranty

The manufacturer’s warranty is 5 years.
