Technology Concept
Gigabit Ethernet (GigE)
Universal connectivity for high-bandwidth industrial data.
Key Advantage
"Long-distance transmission (100m+) using standard, low-cost cabling."
Industrial Connectivity
Gigabit Ethernet (GigE) is the backbone of modern industrial communication. For vision systems, the GigE Vision standard allows for high-speed image transfer (up to 1 Gbps) over standard Cat5e/Cat6 cables.
Data Packet Structure
Unlike simple analog signals, Ethernet transmits data in packets. A typical frame includes the preamble, destination/source MAC addresses, the payload (image data), and a Frame Check Sequence (CRC) to ensure data integrity.

Why GigE for Vision?
- Distance: Supports cable lengths up to 100 meters without repeaters, compared to ~3m for USB 3.0.
- Standardization: Works with standard network switches and cards.
- Power over Ethernet (PoE): Can power the camera and transmit data over a single cable, simplifying installation.
