Complete Guide to Optical Fiber Cables: Solutions for Indoor, Outdoor, and High-Density Networks
Optical fiber cables are the backbone of modern communication networks, enabling high-speed data transmission across telecom, data center, enterprise, and smart city infrastructures. Jiangsu South Communication Technology Co., Ltd., known as Nanfang Communication, is a subsidiary of South Communication Holdings Limited (Stock Code: 1617.HK) and has been manufacturing optical fiber cables and related passive components since 1992. This guide provides a detailed overview of optical fiber cable types, their applications, and how Nanfang Communication’s products address the demands of indoor, outdoor, and high-density network deployments.

What Is an Optical Fiber Cable?
An optical fiber cable is a physical-layer transmission and distribution infrastructure that provides signal transmission, fiber distribution, and patching/access functions. It consists of one or more optical fibers (silica glass cores) enclosed in protective sheathing and strength members. Nanfang Communication’s GYTA53 model is a typical outdoor armored optical cable designed for telecommunications, ISP, data center, FTTx, enterprise, industrial, smart city, 5G backhaul, and metropolitan backbone network scenarios. Its core material is silica glass, strength members are made of FRP, and armoring includes galvanized steel wire or steel tape. Sheath options are PE (polyethylene) or LSZH (low smoke zero halogen). Common fiber types include G.652 and G.657, with attenuation and tensile strength specified per model datasheet.
Industry Background: Why Optical Fiber Cables Matter
The global demand for bandwidth continues to rise, driven by 5G backhaul, FTTH/broadband access, data center interconnects, and industrial IoT. Optical fiber cables serve as the passive foundation of these networks, requiring low attenuation, high tensile strength, and protection against environmental factors such as moisture, rodents, and temperature extremes. According to industry standards, cables used outdoors must be waterproof, crush‑resistant, and weatherproof, while indoor cables often require flame‑retardant or LSZH sheaths. Nanfang Communication’s product portfolio covers both indoor and outdoor cables, ribbon cables, loose‑tube cables, bow‑type drop cables, and specialty cables for custom applications.

Step‑by‑Step Guide to Choosing the Right Optical Fiber Cable
- Determine the deployment environment: Indoor (riser, plenum) vs. outdoor (aerial, duct, direct burial). Indoor cables typically use LSZH or PVC jacket; outdoor cables require PE sheath, water‑blocking, and armor.
- Select fiber type and core count: Single‑mode (G.652, G.657) for long‑haul, multimode (OM3/OM4/OM5) for short‑reach data centers. Core count ranges from 2 to 144+ depending on network capacity.
- Consider mechanical requirements: Tensile strength, crush resistance, minimum bend radius. GYTA53 uses steel tape armor for rodent protection.
- Evaluate connectorization: Pre‑terminated assemblies (e.g., MTP/MPO fan‑out cables) reduce installation time and improve performance. Nanfang Communication’s fan‑out cables support 40G/100G/400G SR4/PSM4 module connections.
- Verify compliance and certifications: Nanfang Communication holds ISO9001, TL9000, ISO14001, OHSAS18001, ISO50001, and the Integration of Informatization and Industrialization Management System. It is recognized as a High‑tech Enterprise and National‑level Green Factory.
