Cisco SFP-10G-T-X Compatible 10GBASE-T SFP+ Copper RJ-45 30m Transceiver Module

Overview

The SFP-10G-T-X Compatible transceiver offers a cost-effective and flexible way to connect 10 Gigabit Ethernet devices using standard copper cabling. While most SFP+ slots are designed for fiber optics or DAC cables, this module converts the port to a standard RJ45 interface, allowing you to use familiar Cat6a or Cat7 patch cables.

Designed for short-reach connectivity within racks or between adjacent equipment, this module supports link lengths up to 30 meters (100 feet) at full 10Gbps speeds. It is an excellent solution for connecting servers, storage arrays, and switches where running fiber optic cabling is impractical or where existing copper infrastructure is preferred.

Key Features

• Interface: Standard RJ45 connector.
• Cabling Support: Requires Cat6a or Cat7 shielded cabling for 10G performance.
• Reach: Up to 30 meters at 10Gbps.
• Auto-Negotiation: Often supports backward compatibility with 100Mbps and 1000Mbps (1Gbps) networks (depending on host switch capabilities).
• Power Efficiency: Optimized power consumption (typically < 2.5W) to fit within SFP+ MSA power envelopes.
• Simplicity: Plug-and-play installation with no specialized fiber cleaning tools required.

Applications

The SFP-10G-T-X is widely used in data centers and enterprise wiring closets for:

• Server Connectivity: Connecting servers with onboard 10GBASE-T (RJ45) NICs to fiber-based Top-of-Rack (ToR) switches.
• Edge Switches: Uplinking copper-based edge switches to a fiber aggregation switch.
• Storage Arrays: connecting NAS or SAN units utilizing copper 10G interfaces.
• Temporary Links: Creating quick, reliable 10G links using readily available patch cords.

Specifications

Cross-Platform Compatibility

Our 10GBASE-T copper modules are coded to communicate effectively with major networking equipment manufacturers. They are compatible with systems that support high-power SFP+ modules, including:

Advantages of 10G Copper SFP+

While fiber optics offer longer distances, the SFP-10G-T-X offers convenience. Copper patch cables are durable, inexpensive, and easy to terminate or replace. This module bridges the gap between fiber-optic infrastructure and copper-based endpoints without requiring a separate media converter.

FAQ (Technical & Product Questions)

1. Why does this module get hot?

10GBASE-T conversion requires significantly more power than fiber conversion. These modules typically consume around 2.5W, which generates heat. This is normal operation. Ensure your switch has adequate airflow and do not install these in every single port of a fully loaded 48-port switch if the switch lacks sufficient cooling capacity.

2. Can I use Cat5e or Cat6 cable?

For reliable 10Gbps speeds, you must use Cat6a or Cat7 cabling. While Cat6 might work for very short distances (e.g., under 10-15 meters) with potential crosstalk issues, Cat5e will not support 10G speeds reliably.

3. Does this support 80 meters like some other modules?

No. This is the standard reach model, limited to 30 meters. The 80-meter versions are specialized “ultra-long reach” copper modules that consume even more power. For most rack-level connections, 30 meters is sufficient.

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

Generally, no. SFP+ modules physically fit in SFP ports, but a 10GBASE-T module usually requires a 10G host interface. However, if plugged into a 10G SFP+ port, the module can often auto-negotiate the link speed down to 1G to talk to a legacy device on the other end of the copper cable.

5. Can I connect this to a standard PC network card?

Yes, as long as the PC has a 10GBASE-T network card and you use a Cat6a patch cable, this module will allow your fiber switch to communicate directly with the PC.
