4-core optical fiber cable Gyta

A 4-core optical fiber cable contains four individual optical fibers, designed for high-speed data transmission in both indoor and outdoor environments.

Overview

A 4-core optical fiber cable consists of four separate optical fibers enclosed within a protective jacket. These cables are commonly used for FTTH (Fiber to the Home), GPON networks, and industrial or outdoor installations. They provide reliable, high-speed data transmission, often supporting bandwidths up to 100 Gbps depending on the fiber type and installation environment.

Construction

Typical 4-core fiber optic cables include the following components: Optical fibers: Single-mode (OS2) or multi-mode fibers for light transmission. Loose tube or PBT tube: Encases the fibers with a jelly compound to protect against moisture and mechanical stress. Strength members: Multi-strand aramid yarn or fiberglass rods to provide tensile strength.

Outer jacket: PE or TPU material for protection against abrasion, UV, water, and temperature extremes. Optional armor: Metal steel or stainless steel mesh for enhanced durability in harsh outdoor environments.

Types

Armored 4-core cables: Designed for outdoor use, resistant to rodents, mechanical damage, and extreme weather conditions. Unarmored 4-core cables: Suitable for indoor or conduit installations where physical protection is less critical. Drop cables: Round, flexible cables used to connect the end user to the network, often in FTTH applications.

ApplicationsFTTH and GPON networks: Connecting homes and businesses to high-speed fiber networks. Industrial and outdoor installations: Roads, construction sites, and harsh environments requiring robust cables. Data centers and LANs: Short-distance high-speed connections within buildings or campuses.

Installation and Testing4-core fiber cables are designed for easy installation with LC connectors for plug-and-play connectivity. They can be installed overhead, direct burial, or in conduits. Testing is typically performed using OTDR (Optical Time Domain Reflectometer) to verify splice loss, measure length, and detect faults.

Pricing and Suppliers

In India, 4-core fiber optic cables are available from multiple suppliers, with prices starting around ₹20 per meter for standard cables, while armored or industrial-grade cables may cost more. Leading manufacturers include Finolex, Jera Line, and various IndiaMART suppliers. Key AdvantagesHigh-speed, low-loss data transmission.
