Butterfly-shaped optical cables, commonly used in FTTH networks, are available in both indoor and self-supporting outdoor variants. Indoor cables are often supplied in spools of 100 meters or 500 meters, suitable for routing through walls, conduits, or ceilings, while self-supporting outdoor cables can be delivered in longer reels, sometimes up to 2 km or more, to span from distribution points to subscriber buildings . The exact length depends on the installation scenario, fiber core count, and whether the cable is pre-connectorized.
In practice, indoor butterfly cables are usually 100–500 meters per reel, while outdoor self-supporting variants can range from 500 meters to 2 km or more, depending on network design and deployment needs. The choice of length should consider fiber type, bend radius, and installation environment to ensure optimal performance and minimal signal loss .
