Cable network engineering, in one calculator.
DataOverCable Engineering sizes DOCSIS 3.0, 3.1 and 4.0 networks: capacity, splits and spectrum, OFDM bit loading, noise, growth, latency and distributed access. It runs offline, and your inputs never leave your device.

Traffic engineering
Serving group and MAC domain capacity for DOCSIS 3.0, 3.1 and 4.0, with Erlang B voice, Cloonan sizing and service tiers.
Plant and spectrum
Low, Euro, mid and high split, ESD to 684 MHz and FDX, an automatic downstream lineup and total composite power.
OFDM and OFDMA
Channel calculator with pilots, PLC, NCP and LDPC, adaptive bit loading with spec CNR thresholds and profiles A–D.
RF analysis
Symbol, codeword and packet error rates versus SNR, exact SER for square and AMPM QAM, throughput and RF budgets.
Planning
Growth forecasts and years to exhaust, node splits, latency and Low Latency DOCSIS, saved scenarios side by side.
Distributed access
Remote PHY versus Remote MACPHY: digital optics gain, CIN latency, DEPI/UEPI backhaul and nodes per uplink.
