Kramer's FM4/FM4 cables are high performance cables with 4pin 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 doubleshielded data cables, in an overall doubleshielded outer jacket.
- High Quality Connectors - Molded 4pin connectors on both ends. The 4pin connector is popular on cameras and other small devices due to its compact size, but does not support power transmission.
