Strip the coating around 15~20mm, keep the length according to actual bare fiber adapter, then wipe the fiber. Check the fiber endface, adjust the fiber. Hi guys,In this video we demonstrate how to splice transparent fiber optic cables with precision and clarity. Watch step-by-step as we prepare, align, and fuse the fibers for a flawless optical connection. In this tutorial. Fiber optic adapters play a critical role in ensuring stable and low-loss fiber connections. Bare fiber adapters are mainly used to connect the fiber jumper, pigtail which without polished with bare fiber to test the link. By following these steps and precautions, you can ensure a reliable and high-quality connection with LC fiber connectors, enhancing the stability and performance of your network. A fiber optic coupler works by precisely.
