Flat butterfly drop — indoor, self-supporting & duct versions. Factory-terminated and 100% tested before shipment.
The bow-type (butterfly) drop cable is the last hundred meters of every FTTH network: bend-insensitive G.657 fiber between two FRP or steel strength members in a flat LSZH profile that staples, bends and terminates with field-installable connectors.
Four constructions cover the whole drop route — click the version options to preview each: standard indoor 1–2F (3.0×2.0 mm), 4-fiber indoor (4.0×2.0 mm), self-supporting aerial with steel messenger for pole-to-wall spans, and the round waterproof duct version with AL-plastic moisture barrier.
All versions splice or terminate identically at the subscriber end, so installers stock one accessory kit across the plant.

Indoor flat versions run inside buildings and along walls; the messengered version flies from pole to building unsupported up to ~50 m; the round waterproof version handles buried or ducted approaches. Many drops chain versions — duct to the wall, flat up the riser.
Every assembly undergoes 100% optical inspection plus insertion- and return-loss testing to IEC, TIA/EIA and Telcordia standards. Test reports are available on request.
Yes — length, jacket color and material (PVC / LSZH / OFNP / OFNR), cable diameter (0.9 / 2.0 / 3.0 mm) and any connector combination are OEM/ODM customizable.
