The FTTH Drop Fiber Cable is also called butterfly optical cable because it looks like a butterfly in cross section. Whether in data centers, home entertainment systems, or industrial machinery, these cables prove their worth. They feature advantages such as small outer diameter, light weight, low cost, reliable performance, and easy installation, making them the dominant product for fiber-to-the-home (FTTH) optical cable. For self-supporting access network, the butterfly introduction of indoor optical cable positions the communication unit in the center, with two parallel non-metallic strength members (FRP) placed on both sides. Additionally, an outer steel wire strength member is attached, and finally, it is.
