Cisco SFP-GE-T
1000BASE-T Copper SFP (NEBS 3 ESD), Original Cisco
Product Highlights
When your network demands Gigabit Ethernet over copper but your environment calls for carrier-grade durability, the Cisco SFP-GE-T delivers on both fronts. This original Cisco 1000BASE-T copper SFP transceiver module plugs into any SFP-equipped Cisco switch, router, or platform and provides reliable 1 Gbps connectivity over standard Category 5e or Category 6 UTP cabling at distances up to 100 meters.
What sets the SFP-GE-T apart from Cisco's other 1000BASE-T SFP options is its NEBS Level 3 ESD certification. Built to meet GR-63-CORE and GR-1089 standards, this module withstands environmental stresses — including electrostatic discharge, temperature extremes, and vibration — that would compromise commercial-grade transceivers. Its extended operating temperature range of -5°C to 85°C makes it suitable for central offices, outdoor cabinets, and other non-climate-controlled spaces.
The SFP-GE-T supports 10/100/1000 auto-negotiation and Auto MDI/MDIX, enabling seamless integration into mixed-speed copper environments. As a hot-swappable SFP module, it can be installed or replaced without disrupting the host device. For IT teams managing service-provider edge deployments, telecom infrastructure, or mission-critical enterprise networks, the Cisco SFP-GE-T provides the ruggedness and reliability that standard copper SFPs cannot match.
Features & Benefits
NEBS Level 3 ESD Protection
The SFP-GE-T is certified to NEBS Level 3 standards (GR-63-CORE and GR-1089), the highest tier of the Network Equipment Building System framework. This guarantees maximum operability under environmental stresses including electrostatic discharge, seismic events, and temperature extremes — making it the right choice for carrier-grade and mission-critical deployments.
Extended Operating Temperature
With an extended temperature range of -5°C to 85°C, the SFP-GE-T operates reliably in environments that fall outside the comfort zone of commercial-rated transceivers. Deploy it in central offices, outdoor enclosures, or industrial settings where temperature fluctuations are a fact of life.
1000BASE-T Copper Gigabit Ethernet
Delivering full-duplex Gigabit Ethernet over standard Category 5e/6 UTP copper cabling, the SFP-GE-T reaches up to 100 meters (328 ft). It supports 10/100/1000 auto-negotiation and Auto MDI/MDIX, eliminating the need for crossover cables and simplifying integration into existing copper infrastructure.
Hot-Swappable SFP Form Factor
The standard SFP (mini-GBIC) form factor allows the SFP-GE-T to be inserted or removed from a live device without powering down. This minimizes maintenance windows and keeps your network running during upgrades or replacements.
Original Cisco Quality
As a genuine Cisco transceiver, the SFP-GE-T is factory-programmed with Cisco-specific coding, ensuring full compatibility and zero interoperability warnings on Cisco switches and routers. No third-party workarounds or service unsupported-transceiver commands required.
Deployment Scenarios
Service Provider Central Office
Telecom and service provider environments often mandate NEBS Level 3 compliance for all installed equipment. The SFP-GE-T meets GR-63-CORE and GR-1089 requirements, making it the appropriate copper SFP for management interfaces, out-of-band connectivity, or low-density GbE uplinks in central office racks.
Enterprise Campus Access Layer
Use the SFP-GE-T to connect access-layer switches to endpoints, IP phones, or wireless access points over existing copper runs. Its 10/100/1000 auto-negotiation ensures backward compatibility with legacy devices while delivering full Gigabit speeds to modern hardware.
Industrial or Non-Climate-Controlled Environments
Warehouses, manufacturing floors, and outdoor enclosures experience temperature swings that exceed commercial SFP ratings. The SFP-GE-T's extended temperature range of -5°C to 85°C ensures stable operation where standard transceivers would be at risk of failure.
Mission-Critical Network Infrastructure
For networks where uptime is non-negotiable — healthcare, financial services, emergency services — the NEBS 3 ESD rating provides an extra layer of assurance against electrostatic discharge and environmental stress, reducing the risk of transceiver-related outages.

Compatibility Notes
The Cisco SFP-GE-T is compatible with a wide range of Cisco platforms that support 1000BASE-T SFP modules, including various Catalyst, Nexus, and ASR series devices. Always verify compatibility for your specific platform and IOS/IOS-XE/NX-OS version using the Cisco Transceiver Compatibility Matrix.
Note: The Cisco SFP-GE-T reached End-of-Sale on June 1, 2017 and has been replaced by the GLC-TE for new Cisco orders. The SFP-GE-T remains fully functional and supported in existing deployments. Refurbished and secondary-market units are widely available.
