Cisco SFP-10G-T-80 Compatible 10GBASE-T SFP+ Copper RJ-45 80m Transceiver Module

Overview

Upgrade your network connectivity with the SFP-10G-T-80 Compatible transceiver, a high-performance solution designed to overcome the traditional distance limitations of copper SFP+ modules. While standard 10GBASE-T transceivers typically max out at 30 meters, this Extended Reach module utilizes advanced PHY technology to drive 10 Gigabit Ethernet signals up to 80 meters over shielded Cat6a or Cat7 cabling.

Equipped with a standard RJ45 interface, this module allows for seamless integration into existing copper infrastructures. It is an ideal solution for connecting servers, storage arrays, and switches within data centers or enterprise wiring closets where fiber runs are not feasible, yet distances exceed the standard 30-meter limit.

Key Features

• Extended Reach: Supports 10Gbps data transmission up to 80 meters (approx. 262 ft) over Cat6a/Cat7 cable.
• Interface: Standard RJ45 connector.
• Multi-Rate Support: Often backward compatible with 100M/1G/2.5G/5G networks (switch dependent).
• Cabling: Optimized for usage with Twisted Pair Cat 6a or Cat 7 cables.
• Cost-Effective: Eliminates the need for expensive media converters or new fiber runs for mid-range distances.
• Compliance: Fully compliant with SFP+ MSA, IEEE 802.3an, and IEEE 802.3az standards.

Applications

The SFP-10G-T-80 is designed for high-speed connectivity in environments relying on copper infrastructure:

• Data Center Top-of-Rack: Connecting switches to servers located in adjacent rows or further down the row than standard DAC cables can reach.
• Enterprise LAN: Linking distribution switches to access switches across different rooms within the 80m limit.
• Storage Area Networks (SAN): High-speed NAS and iSCSI connections over copper.

Specifications

Cross-Platform Compatibility

This 10GBASE-T 80m module is programmed to be compatible with a wide range of networking equipment. It functions as a drop-in replacement for the following OEM parts (note: OEM parts are often limited to 30m; this module offers superior reach while maintaining compatibility):

Advantages

The primary advantage of the SFP-10G-T-80 is flexibility. By more than doubling the standard range of copper SFP+ modules (from 30m to 80m), it fills a critical gap in network design. It allows network administrators to utilize existing copper cabling for 10G uplinks without resorting to fiber optics, significantly reducing installation time and material costs.

FAQ (Technical & Product Questions)

1. Why choose the 80m version over the standard 30m version?

If your cable run exceeds 30 meters, the standard module will experience signal degradation or link failure. The 80m version uses a more powerful PHY chipset to push the signal further, ensuring stability for runs between 30m and 80m.

2. Does this module get hot?

Yes. 10GBASE-T conversion requires significant power (typically 2.5W to 3W). This is physically warmer than fiber optic SFPs or DAC cables. Ensure your switch has adequate airflow and cooling. Do not fill a switch entirely with these modules without verifying the switch’s thermal and power budget.

3. Can I use Cat5e or Cat6 cable?

For the full 80m reach at 10Gbps, you strictly need Cat6a or Cat7 shielded cabling. While Cat6 might work for very short distances (e.g., under 30m), it is not reliable for 80m at 10G speeds. Cat5e is not recommended for 10G.

4. Will this work in a 1G SFP port?

Generally, no. SFP+ modules are designed for SFP+ slots. However, some SFP+ slots can negotiate down to 1G speeds depending on the switch software, but the module physically requires an SFP+ cage.

5. Is it compatible with Cisco equipment?

Yes, the module is coded with Cisco-compatible firmware (or other brands as requested) and will be recognized as a valid transceiver, allowing the port to come up seamlessly.
