The Moxa SFP-1G10BLC-T is an industrial-grade, 1-port Gigabit Ethernet SFP transceiver module, developed as an accessory for a wide range of Moxa Ethernet switches. It enables optical data transmission over fiber optic cables and allows flexible integration into industrial network infrastructures. The module is designed as a hot-pluggable transceiver, meaning it can be inserted into or removed from the switch without interrupting network operation. It supports digital diagnostics (DDM), enabling monitoring of optical parameters such as transmit power and receiver sensitivity. Signal detection is performed via TTL signals, and the inputs and outputs operate with differential LVPECL signals, ensuring robust and interference-resistant data transmission.

Applications
This module is designed for industrial applications, particularly in environments with high requirements for reliability and operational safety. The T model designation indicates the wide-temperature variant, designed for operating temperatures from -40 to 85 °C. This makes the module suitable for use in locations such as production halls, outdoor installations, vehicles, or marine environments where extreme temperature fluctuations may occur. Certification according to EN 60825-1 (Laser Class 1) ensures safe operation without risk to the human eye.

Functions and Features in Detail
The SFP-1G10BLC-T is a single-mode module with a wavelength of 1550 nm, designed for a maximum reach of 10 km. It uses an LC duplex connector, which is standard for most fiber optic applications. The optical transmit power ranges from -9.5 to +5 dBm, while the receiver sensitivity reaches up to -33 dBm. This results in a link budget of up to 31 dB, enabling a stable connection even at low signal strength. The dispersion penalty is 1–5 dB, accounting for the effects of chromatic dispersion in the fiber optic cable.

Technology Explained Simply
The module operates according to the IEEE 802.3z standard, which defines Gigabit Ethernet transmission over fiber optic cables. The use of single-mode fiber (SMF) with a 1550 nm wavelength enables high bandwidth and long transmission distances, as the light waves remain focused within the core of the fiber. The 1550 nm wavelength is particularly suitable for long distances, as it exhibits lower attenuation losses in fiber optic cables. TTL signal detection ensures that the module reports the connection status (active/inactive) to the switch, which is important for network management.

Compatibility and Accessories
The module is specifically developed for use with industrial Moxa Ethernet switches. It is part of the SFP-1G series, which includes various models for multi-mode, single-mode, and WDM fiber types. The WDM models (Wavelength Division Multiplexing) allow multiple wavelengths to be used on a single fiber optic cable, thereby increasing the capacity of existing infrastructure. For models SFP-LHX, ZX, EZX, EZX-120, and WDM, an optical attenuator is recommended to optimize signal quality.

Installation and Mounting
Installation is performed by simply inserting the module into the corresponding SFP slot of the switch. Due to the hot-pluggable feature, no interruption of network operation is required. Connection to the fiber optic cable is made via the integrated LC duplex connector. Proper alignment of the connector is important to ensure a stable optical connection.

Operational Advantages
The module offers high operational reliability due to its wide-temperature readiness and robust construction. Digital diagnostics (DDM) enable proactive monitoring of optical parameters, which is helpful for maintenance and troubleshooting. Certifications according to UL 62368-1, IEC 62368-1, EN 55032/35, FCC Part 15B, ICES-003, and IEC 61000-4-2 to -4-11 guarantee high EMC and safety compatibility. The DNV certification also makes the module suitable for marine applications. The 5-year manufacturer’s warranty underscores the product’s reliability.

Scope of Delivery
The scope of delivery includes 1 x SFP-1G module and 1 x warranty card.
