Summary Lumina provides a visual drag-and-drop canvas on which engineers build DWDM networks from shelf-based equipment, then run a physics-based simulation to validate optical power budgets, OSNR margins, dispersion, and fault resilience before any fiber is deployed. It is used by telecom network engineers, optical network planners, network designers, technical trainers, and students. Category: DWDM simulator, optical network simulator, optical network planning software. --- ## 2. Core capabilities ### Network design - Visual drag-and-drop topology canvas using real-world shelf equipment. - Network Design Wizard auto-generates complete DWDM networks from a few inputs: node count (2-10), per-span fiber lengths, system capacity up to 96 wavelengths, channel spacing of 100 or 50 GHz, and per-node add/drop channel plans. - The wizard assigns shelf types, calculates EDFA gains that compensate insertion losses, validates OSNR and power thresholds, and runs a full simulation. - Quick-start topology templates for ring, linear, mesh, and star designs. ### Simulation engine The engine processes signals card by card and models these physical effects: - Optical power in dBm at every node, accounting for fiber loss, connector and splice loss, EDFA gain, and multiplexer/demultiplexer insertion loss. - OSNR, tracked as cumulative ASE noise through every amplifier stage. - BER, derived from OSNR and the modulation format. - Chromatic dispersion accumulation, with DCM compensation. - Receiver sensitivity, as a pass or fail check against transceiver thresholds. Simulation features: live mode with recomputation on change, per-channel analysis across ITU-T C-band channels, waterfall power budget reporting from transmitter to receiver with margin calculation, and automatic VOA attenuation recommendations when margins are excessive. ### Analysis tools - Signal analyzer showing OSNR across nodes and per channel across the C-band. - Standalone power budget calculator with six adjustable parameters: transmit power, fiber length, attenuation, splice loss, receiver sensitivity, and safety margin. Returns a link pass or link fail verdict with margin, a signal-power-versus-distance curve, a loss breakdown, and a formula reference. - Spectrum analyzer for per-channel power and OSNR across 44 C-band channels. - Channel loading and capacity planning across OOK, QPSK, 8-QAM, 16-QAM, and 64-QAM. - Side-by-side comparison of two to five network configurations. - Full ITU-T G.694.1 C-band wavelength grid reference at 100, 50, and 12.5 GHz. ### Health monitoring and alarms Alarms recompute automatically whenever simulation results change. Eighteen conditions are monitored across five categories: power (loss of signal, low power, power degradation, receiver overload), OSNR (critical and low), BER (critical and elevated), equipment (amplifier failure and degradation), fiber (fiber cut, high span loss, no signal), dispersion (high dispersion), and client (unconfigured lambda). Dashboard metrics include a health score, an active alarm count broken down by severity, average network power, minimum OSNR, and a chronological event log with an acknowledgement workflow. ### Fault injection and resilience testing Four fault types can be injected: fiber cut (complete signal loss on both fibers of a span), amplifier failure (EDFA gain reduced by 0-100%), power degradation (additional span loss from ageing or bending), and elevated BER. After injection the power budget report, signal analyzer, and canvas indicators update immediately, and protection recommendations are generated. ### OTN trace monitoring Full ITU-T G.709 SAPI/DAPI trace byte management, including per-channel transmit and receive trace validation with match/mismatch status, auto-discovery of TX/RX pairs through topology analysis, and one-click generation of SAPI/DAPI defaults from node labels. ### Protection and restoration Six schemes are analyzed: ASON (optical and electrical), SNCP rings with east and west direction analysis, MS-SPRING on two-fiber and four-fiber rings with span and ring switching, 1+1, 1:1, and mesh restoration. Restoration timing is broken down by phase and checked against the ITU-T G.841 50 ms target. ### Client-side distribution Transponder cards map one client signal to one lambda. Muxponder cards aggregate N clients onto one lambda. A cross-connect card provides a visual drag-and-drop port mapper with an auto-map function. Eleven client port types are supported: GbE, 10GbE, 100GbE, STM-1, STM-4, STM-16, STM-64, OC-3, OC-12, OC-48, and OC-192. ### Knowledge base Fifty searchable reference articles across five categories: components (13), physics and concepts (9), standards and protocols (4), protection and resilience (6), and product feature guides (18). ### Project management Networks can be saved and reloaded with full preservation of nodes, edges, card configuration, and simulation state. --- ## 3. Equipment model Four shelf types: - OTM — optical terminal multiplexer, a full transmit/receive terminal with MUX, DEMUX, ROADM, lambda/SFP, and client cards. - OLA — optical line amplifier for in-line amplification on long-haul spans. - ROADM — reconfigurable add-drop at wavelength level using a WSS. - REG — regenerator providing optical-electrical-optical restoration. Sixteen card types across these functions: fiber interfacing unit, EDFA pre-amplifier, EDFA booster, AWG multiplexer, AWG demultiplexer, WSS ROADM, optical switch, lambda/SFP transceiver, dispersion compensation module, variable optical attenuator, splitter, regenerator, power meter, transponder, muxponder, and cross-connect. --- ## 4.

Common questions **What is a DWDM simulator?** A DWDM simulator models a dense wavelength division multiplexing network before deployment, letting engineers evaluate optical paths, channel power, span loss, amplifier gain, OSNR, receiver margin, and fault behaviour. **How is an optical power budget calculated?** Start from transmitter output power, subtract fiber attenuation over distance, splice and connector loss, and multiplexer and demultiplexer insertion loss, then add amplifier gain. Compare the result against receiver sensitivity; the difference is the engineering margin. Lumina computes this as a waterfall from transmitter to receiver and returns a pass or fail verdict with the remaining margin. **What should you look for in a DWDM simulator?** Physical-layer modelling rather than diagramming alone: cumulative OSNR tracking through amplifier stages, power accounting including insertion and splice losses, chromatic dispersion with compensation, receiver sensitivity checks, standards-based channel plans, and fault injection. Lumina provides each of these. **Who is Lumina for?** Telecom network engineers, optical network planners, network designers, technical trainers, and students. **Is Lumina free?** No. Lumina is commercial software with flexible licensing tailored to individual engineers, university departments, or telecom operators.
