Cabling & Power tools
Physical layer planning: PoE class budgets, copper reach limits, conductor sizing, voltage drop, rack units and UPS runtime.
DC Voltage Drop Calculator
Calculate DC voltage drop over a cable run for remote radios, cameras and injectors, and check the equipment still receives a usable voltage.
Ethernet Cable & Standards Reference
Copper category ratings, Ethernet standards with real reach limits, and the T568B pinout - the physical-layer facts you need on site.
PoE Budget Calculator
Size a PoE switch budget properly: per-device class draw, cable loss over distance, total switch load and the headroom left for growth.
Rack Power & UPS Runtime Calculator
Calculate rack load, current per phase, UPS runtime and the heat you have to remove - the numbers a colocation order actually needs.
