Average insertion losses as low as _________ have been obtained with multimode graded index and single-mode fibers using ceramic capillaries.

Average insertion losses as low as _________ have been obtained with multimode graded index and single-mode fibers using ceramic capillaries. Correct Answer 0.1 dB

Mechanical techniques for splicing involve the use of an accurately produced rigid tube in which fiber ends are permanently bonded. It utilizes a ceramic capillary in which an epoxy resin is injected through a transverse bore to provide mechanical sealing and index matching. This technique which uses ceramic capillaries provides insertion losses as low as 0.1dB.
