GYTC8A: Obrázok 8 Kábel Samonosný optický kábel Až 60 jadier z vlákien

JET (miniatúrny centrálny trubicový nekovový optický kábel) je navrhnutý so špecifickou štruktúrou. Zahŕňa umiestnenie 250μm jednovidových alebo viacvidových optických vlákien do voľnej trubice vyrobenej z materiálu s vysokým modulom. Táto voľná trubica sa potom naplní vodotesnou zmesou. Okrem toho je okolo vonkajšej strany voľnej rúrky navlečený nekovový výstužný člen, konkrétne vyrobený z aramidu. Nakoniec je kábel pretlačený plášťom vyrobeným z čierneho alebo farebného polyetylénu s vysokou hustotou (HDPE), výsledkom čoho je kompletný a funkčný kábel.

Hlavné vlastnosti

To ensure the waterproof performance of the optical cable, the following measures are implemented:

• Single Steel Wire/FRP Central Strengthening Core: The central part of the cable is reinforced with either a single steel wire or FRP (Fiber Reinforced Plastic) to enhance the structural strength and stability.
• Filling of Loose Tube with Special Waterproof Compound: The loose tube of the optical cable is filled with a specialized waterproof compound. This compound effectively prevents moisture ingress, ensuring that water cannot penetrate the interior of the cable.
• Complete Core Filling: The core of the cable, which consists of optical fiber and cladding material, is completely filled to prevent moisture from entering. The filling process is carried out meticulously to ensure high-quality and uniform filling, thereby improving the overall waterproof performance.
• Plastic-Coated Aluminum Tape (APL) Moisture Barrier: A layer of plastic-coated aluminum tape (APL) is applied to the external covering of the fiber optic cable. This protective coating acts as a moisture barrier, effectively preventing the intrusion of moisture and humidity into the cable.

By implementing these measures, the optical cable can have excellent waterproof performance, significantly enhancing its service life and reliability.

Here are some additional features:

The steel wire strand has an exceptionally high tensile strength, making it convenient for self-supporting overhead laying. This characteristic reduces installation costs by eliminating the need for additional support structures.

The optical cable exhibits superior mechanical properties, ensuring its resilience and durability in various installation scenarios. Additionally, it possesses excellent temperature properties, allowing it to maintain its performance even in extreme temperature conditions.

The loose tube material itself is designed with excellent hydrolysis resistance and high strength. This ensures long-term reliability and protection for the optical fibers within the cable, even in humid or wet environments.

To provide critical protection to the delicate optical fibers, the loose tube is filled with a specially formulated ointment. This ointment acts as a barrier, safeguarding the fibers against moisture, physical damage, and other environmental factors, thus ensuring their optimal performance and longevity.

By incorporating these improvements, the optical cable demonstrates enhanced tensile strength, mechanical durability, temperature resistance, and moisture protection. These qualities contribute to its cost-effectiveness, reliability, and suitability for various installation scenarios.
