Cable Reference Guide
|Ethernet Cables||Maximum Speed||Solid / Stranded|
|Cat6||10Gb/s (50m or less)||Solid for longer lengths|
|Cat6A||10Gb/s (max 80m*)||Solid for longer lengths|
*Depends on cable specification
Stranded vs. Solid Cable
Solid Ethernet cables have a single core of copper. This offers better transmission, allowing the maximum allowable distances to be reached, but are not as flexible as stranded cables.
Stranded Ethernet cables have multiple strands of copper, allowing greater flexibility but shorter maximum distances. Stranded cables are more suitable for touring uses.
Shielded vs. Unshielded
By their design, Ethernet cables have been designed to reject noise. However in certain applications, more protection is required to ensure fault-free operation. Datasafe Cat5e cable provides an overall braid shield.
- 300m maximum length
- All DMX cables should be terminated
- RDM uses the same pair as DMX
- 2nd pair is generally used for proprietary protocols
- Ethernet cable can be used for DMX512-A, but shorter cable limits apply
- DMX and microphone cables are different and have been designed for different tasks
The problem with cable adaptors
Metal cable adaptors, such as 3 to 5 pin, can cause serious damage to a product if plugged directly into the panel-mounted XLR connector. A short cable should be used between the adaptor and panel mounted XLR connector.
Using Power Cables
- Cable diameter (cross sectional diameter) dictates how much current the cable can safely cope with
- Always uncoil cables under load
- Use appropriately heat rated cables (silicone based) when laying cables close to heat sources
- IP rated connectors should still be mounted appropriately, i.e. off the floor and bagged
- Male to male power cables are ALWAYS a bad idea. You would be surprised how many people use them
