Appendix A. Cable Recommendations - Black Box MT160A Manual

MicroCSU/DSU Cards and MicroRacks
The MicroCSU/DSU has been tested using twisted-pair cable with the following
characteristics:
Wire Gauge
19 AWG
22 AWG
24 AWG
For optimum performance from your MicroCSU/DSU, keep the following
guidelines in mind:
• Always use twisted-pair wire—this is not an option.
• Use twisted-pair wire with a capacitance of 20 pf/ft. or less.
• Avoid twisted-pair wire thinner than 26 AWG (in other words, avoid higher
AWG numbers than 26).
• Use of twisted pair with a resistance greater than the above specifications may
cause a reduction in maximum distance obtainable. Functionality should not
be affected.
• Many different environmental factors can affect the maximum distances
obtainable at a particular site
