The Moxa SFP-1GLHLC-T is a 1-Port Gigabit Ethernet SFP module, developed as an optional extension for various Moxa Ethernet switches. It enables connection via fiber optic cables and is designed for use in industrial networks where high reliability and stable data transmission are required. The module is hot-plug capable, meaning it can be inserted into or removed from the switch without shutting down the system. It complies with the IEEE 802.3z specification and supports data transmission rates of 1000 Mbit/s over fiber optic cables. The integrated digital diagnostic function (Digital Diagnostic Monitor, DDM) allows monitoring of performance parameters such as transmit power, receive sensitivity, and temperature, enabling early detection of performance degradation or faults.

Applications
This module is suitable for industrial applications, particularly in environments with high requirements for operational safety and temperature resistance. It is used in networks that require long-distance cabling, such as in power supply, transportation infrastructure, or manufacturing automation. The variant with an extended temperature range (-40 to 85 °C) is especially suited for harsh environments such as outdoor installations or production halls with significant temperature fluctuations.

Functions and Features in Detail
The SFP-1GLHLC-T features an LC duplex connector designed for connection with standard fiber optic cables. It is a single-mode transceiver module designed for a typical transmission distance of 30 km. The wavelength is 1310 nm, which is standard for single-mode networks. The laser product classification 1 according to EN 60825-1 ensures safety during use near personnel. Optical characteristics include a maximum transmit power of +5 dBm and a minimum receive sensitivity of -33 dBm, enabling a stable connection over the specified range.

Technology Explained Simply
The module uses the Small Form-factor Pluggable (SFP) standard technology, which provides a compact and standardized interface for network modules. The use of single-mode fiber enables high bandwidth and low signal loss over long distances. The DDM function allows continuous monitoring of optical performance, enabling network administrators to detect and resolve potential issues early. The maximum power consumption is 1 W, which classifies the energy consumption as low compared to other modules.

Compatibility and Accessories
The module is specifically designed for use with Moxa Ethernet switches and can be used as an extension for existing networks. It is not intended for use with switches from other manufacturers unless compatibility is explicitly documented by the manufacturers. WDM models (e.g., SFP-10A/B) require paired usage to correctly utilize wavelength pairings.

Installation and Mounting
Installation is performed by simply inserting the module into the corresponding SFP slot of the Moxa switch. Due to its hot-plug capability, no device shutdown is required. Connection to the fiber optic cable is made via the LC duplex connector. Correct alignment and a clean connection are essential to avoid signal loss. Mounting does not require any special tools or additional components.

Operational Advantages
The module provides reliable and stable data transmission over 30 km, making it suitable for applications in large networks. The DDM function enables proactive network monitoring and reduces maintenance time. The high temperature resistance (-40 to 85 °C) expands the range of applications in demanding environments. The low power consumption of up to 1 W contributes to energy efficiency. Certifications according to UL 62368-1, IEC 62368-1, EN 55032/35, FCC 15B, ICES-003, and IEC 61000-4-x series, as well as maritime approval according to DNV, confirm compliance with international safety and emission standards.

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