Title: Thinned optical unit
Inventor: MOGI AKIO
IPC: G02B6/44
Filed: 1989-07-26
Abstract: PURPOSE:To allow leading without damaging the coating layers of optical fibers by coating the assembly of optical fibers with non-crystalline nylon 12 and coating the outer periphery thereof with a PEF resin. CONSTITUTION:The optical fibers 2 are disposed in contact with each other around a central TM 1 and a thin layer 3 of the non-crystalline nylon 12 is applied and formed around the fibers. A coating 4 consisting of foamed polyethylene (PEF) is applied on the outer side thereof. This non-crystalline nylon 12 has excellent tensile strength, tear strength or elongation, etc., but expands and embrittles rapidly when the nylon 12 is brought into contact with ethyl alcohol. The secondary coating layer 4 of the PEF resin on the outer side is, therefore, removed by a cutter and, thereafter, the end part of the unit is immersed into the ethyl alcohol and the swollen thin layer 3 of the nylon can be easily stripped away. The leading operation is thus executed without damaging the coating layers of the optical fibers.
