Everything you need to design a complete Laser Wire® installation — system limits, component selection, module wiring, controller options, and power planning. Written for architects, contractors, and experienced DIY builders planning their first or next Laser Wire® system.
Laser Wire® is a side-emitting plastic optical fiber (POF) lighting system. Unlike EL wire, which is electroluminescent, or LED strip, which uses individual emitter chips, Laser Wire® uses a laser or high-brightness LED source at one end of a fiber strand to transmit light along the fiber length. The fiber jacket is engineered to scatter a controlled percentage of that light outward along the full run, creating a continuous, uniform glow from any angle.
The result is physically different from any other linear lighting technology:
When to specify Laser Wire® over EL wire or LED strip: When any of the following are required — no visible dot structure at close viewing distance, color consistency across long runs (10m+), very thin wire profile (sub-2mm), embedded-in-material applications requiring zero heat, or dynamic RGB color with smooth dimming.
A complete Laser Wire® system consists of four component types:
| Component | Function | Notes |
|---|---|---|
| Source Module | Laser or high-brightness LED that injects light into the fiber end | Capsule Module (single fiber), DMX Module (RGB + dimming), OpalDrive (multi-fiber) |
| Fiber Strand | Side-emitting plastic optical fiber — the visible light element of the system | Multiple diameters; standard and Prism variants; sold by the meter |
| Patch Cables | Pre-terminated fiber segments with connectors at both ends | Used for module-to-fiber connection and for systems requiring field connector joints |
| Power Supply | DC power to the source module; voltage is module-dependent | 12V or 24V DC depending on module type; see power planning section |
The standard fiber profile is a single-layer construction: side-emitting PMMA core with a UV-stabilized outer jacket. Available diameters: 0.75mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm. The 1.5mm diameter is the most commonly specified for general architectural and display applications — it provides sufficient emission output for most environments while routing through tight channels and bends.
The Prism variant uses a dual-layer construction with a prismatic outer jacket that increases side emission output by approximately 40% over standard fiber at the same diameter. Prism fiber is specified for applications where the viewing distance is greater than 3 meters, or where the installation environment has competing ambient light that standard fiber emission doesn't overcome.
Prism is available in the same diameter range as standard fiber but at a higher cost per meter. For most indoor architectural applications, standard fiber is sufficient; Prism is typically specified for large-scale installations, high-ceiling environments, and any application where brightness is the primary driver. See our Prism vs Standard comparison for a full application-by-application guide.
| Parameter | Standard Fiber | Prism Fiber | Notes |
|---|---|---|---|
| Max single-source run | 15m | 12m | Beyond this, brightness falloff at far end becomes visible. Inject from both ends for longer runs. |
| Min bend radius (1.5mm) | 25mm | 30mm | Tighter bends create a bright spot at the bend point and risk fracturing the core. |
| Min bend radius (3.0mm) | 50mm | 60mm | Larger diameter = larger minimum bend radius. Plan channel routing accordingly. |
| Operating temperature | −20°C to +60°C | −20°C to +55°C | Sustained operation above 55°C (Prism) or 60°C (standard) will accelerate jacket degradation. |
| Fibers per DMX module | 1 (standard output) or up to 4 (split with fiber splitter accessory) | Splitting reduces output per fiber proportionally. Use for short runs at close viewing distance. | |
| Fibers per OpalDrive | Up to 6 (dedicated output per fiber) | Each output is independently dimmable. OpalDrive is the correct choice for multi-zone installations. | |
Dual-injection for long runs: For runs longer than 12–15m, inject from both ends using two synchronized source modules. Use a Y-splitter cable to synchronize both modules to the same control signal. Brightness uniformity is substantially better with dual injection than with a single source on an overly-long run.
The Capsule Module is a fixed-color, fixed-brightness source. It accepts a single fiber strand, and the output color is determined at manufacturing time by the laser wavelength or LED emitter color specified at order. No controller is required — connect DC power and the module is on.
Specify the Capsule when: the installation is fixed single-color and dimming or color change is not required. The Capsule is smaller, lower-cost, and simpler than the DMX module for static applications. Full specs: Capsule Module Spec Sheet.
The DMX Module provides full RGB color mixing and dimming control over DMX-512. Each module occupies 3 DMX channels (R, G, B) and can be addressed independently. Use the DMX module when any of the following apply: color must be changeable after installation, dynamic color effects are required, or the installation is part of a larger DMX-controlled system.
The DMX module requires a DMX controller and a DMX data line (XLR cable or DMX-over-Cat5 adapter) in addition to DC power. The module self-terminates if it is the last device in the DMX chain. Full specs: DMX RGB Module Spec Sheet.
OpalDrive is a multi-channel source driver for installations requiring multiple fiber zones from a single controller point. Each OpalDrive unit drives up to 6 independent fiber outputs, each independently dimmable and color-controllable. OpalDrive uses its own control protocol (not DMX) and ships with a dedicated app for setup and programming.
OpalDrive is the correct specification for larger installations — hospitality environments, permanent architectural installations with multiple zones, or any installation where individual zone control is required without per-zone DMX addressing overhead. Details: OpalDrive Product Guide.
| Module | Input Voltage | Current Draw | Max Load per Supply |
|---|---|---|---|
| Capsule Module | 12V DC | 280mA max | Up to 12 modules on a 5A 12V supply (with 20% headroom) |
| DMX RGB Module | 24V DC | 480mA max (full white) | Up to 8 modules on a 5A 24V supply (with 20% headroom) |
| OpalDrive (per unit) | 24V DC | Up to 3.2A (6 outputs at full) | One 5A 24V supply per OpalDrive unit (with 20% headroom) |
Design rule: Always size power supplies to 80% of rated capacity. A 5A supply should carry no more than 4A of load. This provides thermal headroom and accounts for inrush current at startup.
Cable run limitations: 12V systems require larger wire gauge for long supply cable runs than 24V systems for the same load. For supply runs longer than 10m, use 24V modules if available, or upsize supply cable to 14AWG minimum for 12V systems.
Laser Wire® fiber must be cut with a sharp, flat-edged tool — a dedicated fiber cleaver or a fresh single-edge razor blade. A clean perpendicular cut is required for maximum light injection at the source module end. An angled or ragged cut reduces the effective aperture and produces a bright spot at the cut end rather than uniform emission from the source module injection point.
After cutting, lightly sand the cut face with 400-grit then 800-grit sandpaper and wipe clean before inserting into the module. The polished cut face maximizes light coupling efficiency. Our detailed cutting procedure: How to Cut & Connect Laser Wire®.
Laser Wire® fiber can be routed through virtually any channel that maintains the minimum bend radius — aluminum extrusion channels, routed grooves in wood or MDF, silicone tubing, or woven into textile backing. Key routing guidelines:
For upholstery, seating, and soft-goods applications, Laser Wire® is available pre-installed in a welted profile — a fabric-covered piping that can be sewn into seams, tufts, or edges using standard upholstery techniques. The welt integrates the fiber and provides a clean, professional finish without exposed fiber. Details: Welted Profile Guide.
