Loose layer twisted reinforced armored optical cable（GYTA53）_汕头高新区奥星光通信设备有限公司

Product Standard

Product Features

The stable surplus length control and cabling process enable the optical cable to have excellent optical, mechanical, and environmental performance.
The cable core is fully filled with grease to ensure the waterproof performance of the optical cable.
The double sheath structure has excellent compressive and moisture-proof properties
The loose tube material itself has good hydrolysis resistance and high strength
The tube is filled with special grease to provide critical protection for the optical fiber
Good compression resistance and flexibility

Laying methods: direct burial, tunnel, and overhead
