30-1475-02 Cisco SFP Mini-GBIC Transceiver Module

Overview of Cisco 30-1475-02 SFP Transceiver Module 

The Cisco 30-1475-02 SFP Mini-GBIC Transceiver Module with an RJ-45 connector and extended temperature tolerance is a compact, hot-swappable network interface module designed to deliver high-speed Ethernet and Gigabit Ethernet connectivity across copper networking environments. This transceiver supports 1000BASE-T standards and enables seamless network expansions while maintaining exceptional data integrity, thermal stability, and long-range durability.

Designed specifically for environments where space, temperature variability, and network reliability are mission-critical, this SFP transceiver module is fully compatible with a broad range of Cisco network switches and routers. It ensures compatibility, flexibility, and compliance with the IEEE 802.3ab standard, and offers extended support for harsh industrial or outdoor settings.

Key Features of Cisco 30-1475-02 SFP Transceiver

High-Speed 1000BASE-T Ethernet Performance

Supporting 1000BASE-T Gigabit Ethernet connectivity, the Cisco 30-1475-02 SFP module provides robust data transmission speeds up to 1 Gbps over standard Cat5e or higher copper cabling. This capability makes it ideal for high-throughput enterprise applications such as VoIP, video conferencing, virtual desktop infrastructure, and real-time data streaming.

RJ-45 Copper Interface Connectivity

Unlike fiber-based SFP modules, the 30-1475-02 features an RJ-45 interface, allowing it to integrate seamlessly into existing copper infrastructures. It simplifies deployments by removing the need for fiber optic cabling, SFP to LC fiber adapters, or specialized optical network setups. As such, it’s a preferred choice for budget-conscious upgrades and dense data center topologies.

Extended Temperature Range Operation

One of the standout features of the Cisco 30-1475-02 module is its ability to operate within an extended temperature range. This makes it suitable for environments with fluctuating or extreme temperature conditions, including industrial automation, outdoor networking cabinets, and field-deployed switches. With support for temperatures typically ranging from -5°C to 85°C (or better depending on the device revision), this SFP ensures thermal reliability and consistent uptime.

Hot-Swappable Design for Maximum Uptime

The module’s hot-swappable design allows for quick insertion or removal from Cisco switch SFP slots without needing to power down the device. This is critical for mission-critical infrastructure where network availability must be maintained 24/7. It also reduces downtime during maintenance or upgrades.

Technical Specifications and Compliance Standards

IEEE Standards and Compatibility

The Cisco 30-1475-02 complies with IEEE 802.3ab, which defines the 1000BASE-T Gigabit Ethernet standard over copper cabling. It’s also compliant with SFP Multi-Source Agreement (MSA), ensuring it fits within most Cisco SFP-enabled network hardware. Its low latency and high reliability make it an optimal solution for Cisco Catalyst switches, Nexus series, ISR routers, and other compatible platforms.

Distance and Cabling Support

This SFP module supports transmission distances of up to 100 meters over standard Cat5e or higher-rated UTP cables. It is ideal for short to mid-range copper Ethernet links, connecting access layer switches to distribution layer cores or workstations to access points in structured cabling environments.

Connector Type and Physical Form Factor

Featuring a standard RJ-45 connector, the module slots directly into Cisco SFP ports and connects to copper Ethernet cables. Its compact size adheres to the SFP MSA, offering a small footprint ideal for high-density switch environments and rack-mounted networking equipment.

Power Consumption and Environmental Parameters

The Cisco 30-1475-02 operates with low power consumption, typically under 1W, reducing heat output and power draw across large-scale deployments. The extended temperature rating also means it performs reliably in industrial control systems, transportation networks, and other rugged settings without supplemental cooling systems.
