Title: Optical fiber connection part
Inventor: MATSUMOTO MICHITO
IPC: G02B6/24
Filed: 1982-06-23
Abstract: PURPOSE:To prevent a connecting part from causing damage even when water entering an optical fiber core connecting part freezes by providing an external pressure protector around the optical fiber core connection part installed in an optical fiber connection part. CONSTITUTION:The external pressure protector is formed by covering a bare reinforcing container 2 with an airtight cover 4 and filling the airtight cover 4 with a fluid or viscous material 3.
