Issue
Can Sigma devices be connected to an Ethernet Cat7 network?

Cause
There is uncertainty regarding the compatibility of Sigma devices with newer Ethernet cabling standards, particularly Cat7.
Resolution
Yes, Sigma devices can be connected to a Cat7 Ethernet network, provided that the network switches support 100 Mbps (100Base-T) communication.
Sigma devices typically operate at 100 Mbps, which is well within the capabilities of Cat5e, Cat6, and Cat7 cabling. The key factor is not the cable category itself, but whether the network infrastructure (especially switches) supports the required communication speed.
Cable Category Overview
| Cable Type | Frequency | Max Speed | Shielding | Notes |
|---|---|---|---|---|
| Cat5/5e | 100 MHz | Up to 100 Mbps | Unshielded | Common in older installations |
| Cat6 | 250 MHz | Up to 1 Gbps | Improved insulation | Suitable for Gigabit Ethernet; max 55m for 10 Gbps |
| Cat7 | 1000 MHz | Up to 10 Gbps | Shielded (per pair and overall) | Enhanced protection from interference and crosstalk |
Key Considerations
- Ensure network switches are configured to support 100 Mbps communication.
- Cat7 cables offer superior shielding and higher frequency handling, but do not inherently improve Sigma device performance beyond their 100 Mbps capability.
- Using Cat7 may be beneficial in environments with high electromagnetic interference (EMI), but it is not a requirement for Sigma devices.
