Moxa SFP-1G10BLC , SFP interface module, Tx 1550 nm content_copy

The SFP-1G10BLC from Moxa is a 1-port Gigabit Ethernet SFP module designed as an extension for industrial network devices. It enables connection via fiber optic cables and is designed for use in demanding environments. The module supports the hot-plug function, allowing it to be inserted or removed from a compatible device during operation without interrupting network functionality. It features digital diagnostic monitoring (DDM), enabling real-time monitoring of operating parameters such as transmit power, receive level, and temperature. This function is particularly useful for remote maintenance and fault diagnosis in distributed infrastructure. The interface is based on differential LVPECL signals, ensuring robust and noise-resistant data transmission. A TTL signal detect indicator visually indicates the connection status. Connection is made via an LC duplex connector, used for standard and single-mode transceivers; for WDM modules, an LC simplex connector is provided. The module complies with the IEEE 802.3z standard and is certified as a Class-1 laser product according to EN 60825-1, ensuring safety when lasers are used in proximity to people.

Applications
The SFP-1G10BLC is designed for industrial networks, particularly in environments with high mechanical, thermal, or electromagnetic stress. It is suitable for applications in process automation, power supply, transportation, and manufacturing industries, where reliable long-distance data transmission over fiber optic cables is required. The T-model variant, to which the SFP-1G10BLC belongs, is designed for operating temperatures from -40 to 85 °C, making it suitable for outdoor use or in rooms with extreme climatic conditions. Storage is also possible within this temperature range, and humidity may range from 5 to 95 %, provided no condensation occurs.

Functions and Features in Detail
The module is designed as a single-mode transceiver and operates at a wavelength of 1550 nm. It enables a maximum reach of up to 120 km, with the exact reach depending on the type of fiber and optical properties of the cable. Maximum transmit power is -4 to -9.5 dBm, and the receive range is between 0 and -18 dBm. The link budget is 8.5 dB, and dispersion penalty ranges from 4.3 to 5 dB. These values are specified for multimode transceivers, whereas the SFP-1G10BLC, as a single-mode module, operates with different parameters. Power supply is provided by the network device, and maximum power consumption is 1 W.

Technology Explained Simply
SFP modules are small, hot-pluggable transceivers used in network devices such as switches, routers, or industrial PCs to establish connections via fiber optic cables. The SFP-1G10BLC uses single-mode fiber, suitable for long distances, as it transmits only one light mode and thus exhibits lower signal loss. The 1550 nm wavelength is particularly suitable for long transmission distances in the optical range, as it exhibits low attenuation in fiber. The DDM function enables continuous monitoring of optical parameters, which is beneficial for network maintenance and diagnostics. The LVPECL interface ensures high signal integrity, which is especially important in noisy environments.

Compatibility and Accessories
The module is compatible with G.652 fibers, the most commonly used standard single-mode fibers. It can be used in devices that support SFP ports, particularly in industrial network devices from Moxa and other manufacturers using the SFP standard interface. WDM transceivers (Wavelength Division Multiplexing) are used in pairs to transmit two independent data channels over a single fiber optic cable. The SFP-1G10BLC is not a WDM module but a single-mode transceiver for the 1550 nm wavelength. It is not compatible with other WDM modules, as it is not designed for pairing with a counter-module.

Installation and Mounting
Installation is performed by inserting the module into an SFP port of the network device. The hot-plug function allows installation without interrupting operation. Connection to the fiber optic cable is made via the LC duplex connector. Proper alignment of the connector is important to ensure a secure connection. Mounting requires no additional tools, and the module is inserted directly into the port. The connection is visually confirmed by the TTL signal detect indicator.

Operational Advantages
The SFP-1G10BLC offers high reliability and robustness for industrial applications. The T-model version enables operation in extreme temperatures, making it suitable for outdoor use or in industrial halls. The DDM function facilitates remote maintenance and reduces the need for on-site servicing. The hot-plug function allows flexible network design, as modules can be exchanged without interrupting operation. The use of single-mode fiber at 1550 nm wavelength ensures high reach and low signal loss, which is advantageous for long distances in industrial applications. Certifications according to UL 62368-1, IEC 62368-1, IEC 60825-1, EN 55032/35, FCC 15B, ICES-003, and IEC 61000-4-2 to -4-11 guarantee safety and EMC compliance. Maritime approval according to DNV makes the module suitable for use on ships. The 5-year manufacturer's warranty provides additional security for operation.
