OPTICAL CABLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18455712 titled 'OPTICAL CABLE
Simplified Explanation
The optical cable described in the patent application is designed for installation in a microduct and consists of one or more optical-fiber core wires covered by a sheath layer. The sheath layer has a low density and contains an olefin-based resin, silicone, and a non-halogen flame retardant in specific ratios. The olefin-based resin includes polyethylene and an ethylene-vinyl acetate copolymer or an ethylene-ethyl acrylate copolymer, while the silicone has a specific weight-average molecular weight range.
- The optical cable is specifically designed for installation in a microduct.
- The sheath layer of the cable has a density of 2.0 g/cm or less.
- The sheath layer contains an olefin-based resin, silicone, and a non-halogen flame retardant.
- The ratios of non-halogen flame retardant to olefin-based resin and silicone to olefin-based resin are specified.
- The olefin-based resin includes polyethylene and a specific type of copolymer.
- The silicone used in the sheath layer has a weight-average molecular weight within a certain range.

Original Abstract Submitted
An optical cable according to an embodiment of the present disclosure is an optical cable for installation in a microduct, the optical cable including one or more optical-fiber core wires, and a sheath layer covering an outer peripheral side of the one or more optical-fiber core wires. The sheath layer has a density of 2.0 g/cmor less. The sheath layer contains an olefin-based resin, a silicone, and a non-halogen flame retardant. A mass ratio of the non-halogen flame retardant to the olefin-based resin is 0.90 to 2.00. A mass ratio of the silicone to the olefin-based resin is 0.005 to 0.100. The olefin-based resin contains a polyethylene, and an ethylene-vinyl acetate copolymer or an ethylene-ethyl acrylate copolymer. The silicone has a weight-average molecular weight of 50,000 to 1,000,000.
