The fiber termination box is an interface between the fiber cable from the line side and the pigtails to be passed to the fiber distribution frame. A fiber pigtail is a specific hardware connection used for cable termination. A typical PON topology (GPON, XGS-PON, or 25G PON) flows OLT → fiber distribution hub → passive splitters → distribution/drop fibers → premises. Its function is primarily to splice, secure, and protect the optical fibers. FTTP or fiber To The Premises applications have reinforced the importance of reliable and stable fiber optic terminations. It provides a secure environment for splicing, connecting, and managing fibers, ensuring efficient and reliable network. To address these issues, the fiber termination box (FTB) — also known as the optical termination box or fiber distribution box — plays a crucial role in ensuring safe, structured, and efficient fiber connectivity at the network edge.
