New optical fiber connection method using solid refractive index matching material

Faults and Novel Countermeasures for Optical Fiber Connections in Fiber-To-The-Home Networks

“…Therefore, it is important to prevent the gap between fiber ends from becoming wider in joints that employ refractive index matching material. A novel optical fiber connection method that uses a solid resin as refractive index matching material has been proposed [21]. The new connection method provides a high insertion loss that exceeds the loss budget between network devices when there is a wide gap between fiber ends (defective connection) and a suitable low insertion loss when the gap is less than a par-Current Developments in Optical Fiber Technology ticular width (normal connection).…”
