Optical Fiber Cable: Types, Applications & Procurement Guide

Optical Fiber Cable: Types, Applications & Procurement Guide

Jiangsu South Communication Technology Co., Ltd. (brand: Nanfang Communication) is a subsidiary of South Communication Holdings Limited (Stock Code: 1617.HK), established in 1992. The company specializes in the R&D, production, and sales of communication optical cables, fiber optic cables, and related accessories. This guide provides an overview of optical fiber cable types, their applications, and procurement considerations based on verified product and company data.

What Is an Optical Fiber Cable?

An optical fiber cable is a physical-layer transmission medium that uses silica glass fibers to carry light signals. According to Nanfang Communication's product documentation, these cables serve as the transmission and distribution infrastructure for telecommunications, providing signal transmission, fiber distribution, and patching/access functions. Typical components include a core of silica glass, strength members made of FRP, armoring materials such as galvanized steel wire or steel tape, and sheath options of PE or LSZH.

Industry Background

Optical fiber cables are deployed globally in telecom operators, ISPs, data centers, FTTH/broadband access networks, enterprise and campus networks, industrial IoT, smart city projects, and 5G backhaul. They are installed under various conditions: indoor cabling, duct/ducting, aerial/self-supporting, direct burial, and outdoor harsh environments requiring weatherproofing, waterproofing, rodent protection, and temperature resistance. Supporting equipment includes optical modules, PLC splitters, cable splice closures, FTTH distribution boxes, MPO patch panels, fiber optic connectors, fiber assemblies, and WDM units.

Nanfang Communication's Fiber Optic Cable Solutions

Nanfang Communication produces a comprehensive portfolio that includes indoor/outdoor optical cables (e.g., model GYTA53), ribbon optical cables, loose-tube optical cables, bow-type drop optical cables, single-mode and multimode optical fibers, MPO high-density patch panels, PLC optical splitters, fiber optic connectors, and more. The company also offers custom specialty fibers/cables and system integration services. With an annual production capacity of 3,000,000 core kilometers, the company can support large-scale deployments for operators and enterprises.

Step-by-Step Procurement Breakdown

1. Identify your deployment environment – Determine whether the cable will be used indoors, outdoors, aerial, or direct burial. Sheath material (PE for outdoor, LSZH for indoor) and armoring type affect selection.
2. Choose fiber type – Single-mode fibers (G.652, G.657) for long-distance/high-bandwidth; multimode for short-reach data center links. Core count and diameter must match application requirements.
3. Select connector and assembly – For high-density data centers, MPO/MTP pre-terminated cables and fan-out assemblies reduce installation time. For FTTH, bow-type drop cables with pre-connectorized ends simplify last-mile deployment.
4. Verify performance specifications – Key parameters include attenuation (dB/km), insertion loss, return loss, tensile strength, and minimum bend radius. Nanfang Communication provides detailed datasheets per model.
5. Evaluate supplier certifications and reliability – Look for ISO9001, TL9000, environmental management certifications, and a CNAS-accredited laboratory for quality assurance.
6. Request samples or datasheets – Contact the supplier to validate real-world performance and compatibility with existing network equipment.

Use Cases

• FTTH/Broadband Access – Bow-type drop cables and loose-tube cables with PLC splitters are used for connecting homes and buildings to the optical distribution network.
• Data Center Interconnect – Pre-terminated MPO trunks and fan-out cables enable 40G/100G/400G SR4/PSM4 module connections with low insertion loss (typical 0.35 dB).
• 5G Backhaul & Metropolitan Networks – GYTA53 and ribbon cables provide high-fiber-count trunk lines with robust protection against environmental stresses.
• Industrial IoT & Smart City – Outdoor armored cables with waterproofing and rodent protection are deployed in harsh environments.
