JPS5830703A - Fiber having silicone resin clad for optical communication - Google Patents

Abstract

PURPOSE:To obtain an optical fiber with stable transmitting characteristics and high workability by coating the surface of an optical glass fiber as a core with specified silicone resin to form a clad having >=65 hardness. CONSTITUTION:Quartz glass rod is melted and spun to form a glass core 2 for optical communication. The surface of the core 2 is coated with a silicone resin composition having >=65 hardness (Shore A) as a clad layer 3, and a protective coat layer 4 of polyamide or the like is formed on the layer 3 to obtain an optical fiber core line 1. The composition forming the clad layer 3 consists of dimethylpolysiloxane blocked by vinyl groups at both terminals, organohydrogenpolysiloxane and alcohol modified chloroplatinic acid, and >=65 hardness is given to the composition by hardening. The core line 1 is put in the core 6 of a connector and stuck to the core 6 with an epoxy adhesive 5. Thus, an optical fiber with high transmitting characteristics provided with a connector is obtd.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called 7-eye communication system which has stable transmission characteristics and is easy to install.

As a 7-eye glass for optical communication, the quartz glass cover is made of an optical mesh O fiber-like body with a bore, and various polymeric material layers are provided on the Jsllll to make it 1. There is a plastic Kutsud 7 Aipa.

Compared to the 7-eye aid whose studded part is made of quartz, it has a larger refractive index difference, a larger numerical aperture, and a simpler #4F efficiency with an over-reliable light source. The rounded structure and manufacturing of this soft fishing rod is easy. 0 tour #k is a big flower (can be taken, etc.), and it is very hot when it is put into practical use.
A stone that has points.

The polymer material used in the hard layer is wax, which has a small refractive index, but it also contains fluorine. Resin and obi novo 9-S/μ quinane are suitable, and the latter has properties suitable for use in 4HIlo, such as an excellent 9% m as a fiber for optical transmission. It is easily manufactured by Kjll and is widely used from 11 to 4.

However, although Kei 61 has such advantages, 9 Sirigo 7 shoes 7 Eye AK4h has some drawbacks), 41 to 7 Eye Pa Shinso Ok -) Nikle), the core / cladding layer is O protective coating on it Relatively protruding from the layer, ζ07 Aipa core wire with Rin nectar, Marubasha, due to aging) 7 Aipa comes out from the tip of Zunetatar to the center, Go nectar! The tip of the IIR dovecote is 7, and the tip of the 7 eyelids is out of place, resulting in a very large defect.

In order to solve the above problem, we have conducted various studies and found that this 6e drawback is the conventional system 9:
