Network and Fiber Calculators

Network planning has its own set of small calculations that are trivial individually and expensive in aggregate: off-by-two errors in host counts, links that do not close because nobody counted the patch panels, transfer estimates that ignore the difference between bits and bytes. These tools handle the arithmetic so the judgement is left to you.

• Subnet CalculatorCalculate network address, broadcast, usable host range, wildcard mask and host count from any IPv4 address and CIDR prefix.
• Fiber Loss Budget CalculatorCalculate total optical link loss from distance, connectors and splices, and compare it against your transceiver's power budget.
• Data Transfer Time CalculatorWork out how long moving a given volume of data takes at a given link speed, including real-world efficiency overhead.
• Cable Label GeneratorGenerate sequential structured cabling labels from a naming pattern for patch panels, racks and ports.
