Abstract

The invention discloses a high density anti-compression optical fiber bundle optical cable for a data center. The optical fiber herein includes a micro-beam optical fiber, an aramid fiber layer whichcoats outside the micro-beam optical fiber, and a sheath layer which coats outside the aramid fiber layer. The sheath layer is embedded with three non-metal reinforcing members therein. The three non-metal reinforcing members constitute a triangle. The material of the sheath layer is composed of the following components by weight: polyurethane of 20-40 parts, polyvinyl choride of 25-45 parts, polyoxyalkylene modified polymethyl siloxane of 5-15 parts, chemigum of 20-30 parts, dibutoxyethyl adipate of 0.5-2 parts, trioctyl phosphate of 0.4-1 parts, modified filling material of 0.5-2 parts, a fire retardant of 2-4 parts, an activator of 0.2-0.6 parts, and a promoter of 0.5-1 parts. According to the invention, the optical fiber uses a center tubular structure, can ensure the moulding processof the optical fiber free from impact, and can also meet higher mechanical and environmental performances of the optical fiber.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a high-density compression-resistant optical fiber bundle optical cable for data centers. Background technique [0002] High-density compression fiber optic cable for data centers is a new concept product specially proposed for data center wiring. Traditional MPO cables are roughly divided into two categories: combined micro-bundle tube cables and bare fiber bundle cables. Traditional MPO cables have poor tensile and compressive mechanical properties, and some outer sheaths have poor cold resistance, so they cannot be applied to high-density switch backplanes or fiber optic cabling solutions in data center computer rooms. Contents of the invention [0003] The technical problem to be solved by the present invention is how to make the optical cable meet certain performances of lateral pressure resistance and bending resistance, and adopt a low-smoke and halogen-free sheath, and at...
