The GLC-T-RGD is a1000BASE-T Small Form-Factor Pluggable (SFP) transceiver modulemainly designed for Cisco devices and widely used in industrial and enterprise copper gigabit Ethernet networks. Its standout feature is its adaptation to extreme industrial temperature environments, which distinguishes it from ordinary commercial-grade copper SFP modules. Here is a detailed description:

1. Core Transmission Performance
   • Data Rate and Protocol Compliance: It supports a data transfer rate of 1Gbps and is fully compliant with the 1000BASE-T standard and IEEE 802.3-related specifications for gigabit Ethernet. This enables it to stably handle bandwidth-intensive tasks such as large-file transfers and real-time data transmission, meeting the high-speed connectivity needs of industrial control systems and enterprise LANs.
   • Transmission Medium and Distance: Tailored for copper networks, the module uses an RJ-45 connector and works with standard twisted-pair cables (such as Cat 5e and Cat 6). It can achieve a maximum transmission distance of 100 meters, making it suitable for short-range connections and allowing full use of existing copper wiring infrastructure without the need for costly fiber-optic rewiring.
2. Physical and Environmental Traits
   • Form Factor: It adopts the standard SFP plug-in form factor. This compact design enables it to fit into various Cisco switches, routers, and other network devices with limited slot space, facilitating flexible port configuration and device expansion.
   • Industrial-Grade Temperature Adaptability: Unlike commercial-grade modules with a temperature range of 0°C to 70°C, this module excels in withstanding harsh temperatures. It typically operates within the range of -45°C to 85°C (some specifications cite -40°C to 85°C), making it reliable for deployment in extreme environments like outdoor industrial sites, unconditioned equipment rooms, and industrial control cabinets.
   • Electrical and Certification Compliance: It uses a 3.3V single power supply, which helps control overall power consumption of network devices. Additionally, it complies with multiple standards including SFP MSA (Multi-Source Agreement), CE, and RoHS. These certifications ensure its safety, environmental friendliness, and compatibility with other MSA-compliant network equipment.
3. Key Functional Advantages
   • Seamless Compatibility: It is specially optimized for Cisco devices, including Cisco Aironet series wireless access points (such as 1562D/E/I) and Catalyst Embedded ESS 9300 series switches. Third-party compatible versions also preload dedicated codes to match Cisco device requirements, ensuring seamless integration without communication conflicts.
   • Plug-and-Play & Easy Maintenance: As a plug-in SFP module, it supports hot-swapping (a common feature of standard SFP modules). Network administrators can install or replace it without powering off the host device, minimizing network downtime during maintenance or upgrades and simplifying daily management.
4. Typical Application ScenariosThis module is widely used in industrial and enterprise scenarios that demand stable operation in extreme conditions. For example, it connects controllers and monitoring devices in industrial automation systems, links network nodes in outdoor campus networks, and establishes short-range gigabit connections in unattended edge computing equipment rooms. It is also a cost-effective choice for industries like manufacturing, energy, and transportation that require reliable gigabit Ethernet connections in harsh environments.
