Underground 48 96 Core Fiber Optic Cable

High-Performance Underground 48-Core Fiber Optic Cable for Long-Distance Communication

This robust and versatile underground fiber optic cable is engineered for high-capacity data transmission across diverse environments. Designed with a focus on durability, reliability, and performance, it supports both single-mode and multimode fiber configurations—ideal for modern telecom infrastructure, enterprise networks, and broadband deployments. With a core count of exactly 48, this GYTS-type cable offers an optimal balance between capacity and manageability, making it a preferred choice for outdoor fiber installations where strength and environmental resistance are critical.

Key Features:

• 48-core fiber configuration – suitable for metropolitan area networks (MANs), FTTH, and backhaul systems
• Steel wire reinforcement + steel tape armor – enhances tensile strength and mechanical protection
• UV-resistant polyethylene (PE) outer sheath – ensures long-term stability in direct sunlight exposure
• Moisture-blocking filler and gel-filled tubes – prevents water ingress and maintains signal integrity
• Compliant with international standards for outdoor fiber deployment (IEC, ITU-T, TIA/EIA)
• Operates reliably under extreme temperatures (-40°C to +70°C) and humidity levels up to 95%

The construction of this 48-core fiber cable follows the GYTS design standard—an industry-recognized model for armored, moisture-resistant cables used in underground ducts, direct burial, or pipeline installations. Each fiber strand is individually buffered and housed within a central tube filled with water-blocking gel, ensuring minimal attenuation even under harsh conditions. The inclusion of steel wire reinforcement allows for safe pulling through conduits without compromising structural integrity, while the steel tape armor provides excellent crush resistance against heavy loads or excavation activities. This makes the cable ideal for utility corridors, urban fiber rollouts, and rural broadband expansion projects.

Whether deployed via aerial methods using messenger wires or installed directly in underground vaults, this fiber solution excels in delivering consistent bandwidth over extended distances. Its compatibility with both single-mode (SMF) and multimode (MMF) fibers means it can support applications ranging from high-speed internet delivery to video surveillance, cloud computing, and smart city infrastructure. The modular design also simplifies splicing, termination, and testing processes during installation and maintenance phases.

Customers worldwide have praised its resilience in challenging climates—from desert regions with intense UV radiation to coastal areas with high salinity and humidity. Many network engineers highlight its ease of handling compared to bulkier alternatives, as well as its ability to reduce downtime due to weather-related damage. For service providers seeking a future-proofed medium for scalable communication networks, this 48-core fiber optic cable represents a reliable investment.

Frequently Asked Questions:

What is the difference between single-mode and multimode fiber in a 48-core cable? Single-mode fiber supports longer distances (up to 80 km) with lower signal loss, ideal for telecom backbone links. Multimode fiber offers higher bandwidth over shorter runs (up to 2 km), commonly used in LANs and data centers.

Can this cable be used indoors as well? While primarily designed for outdoor use, some variants can be adapted for indoor trunking if properly protected from physical stress and fire hazards.

How does the steel tape armor improve performance? It adds mechanical protection against rodent bites, crushing forces, and soil pressure—critical for underground installations where cable integrity must be maintained over decades.

Is this cable compliant with global safety regulations? Yes, it meets IEC 60794, ITU-T G.652/G.655 standards, and other regional certifications for optical fiber performance and environmental resilience.
