Kramer's FM4/FM4 cables are high performance cables with 4−pin FireWire® connectors at both ends. They are used primarily for data transfer (IEEE 1394) at speeds up to 400Mbps between multimedia devices such as digital cameras, VCRs, CD drives, hard disks, scanners, graphic cards and editing systems.

- Quality Construction - Constructed using two separately double−shielded data cables, in an overall double−shielded outer jacket.
- High Quality Connectors - Molded 4−pin connectors on both ends. The 4−pin connector is popular on cameras and other small devices due to its compact size, but does not support power transmission.
