Optical fiber vs. optical cable: Understand the essential difference of core communication technologies in 3 minutes --AOPTKE FIBER explains the "highway" cornerstone of modern communication

[Changsha, January 27] As the global digital transformation accelerates, optical fiber and optical cable are frequently reported in the newspapers as the "golden partners" of information transmission. Experts from the China Institute of Communications pointed out that 70% of corporate buyers still confuse these two key technical concepts. This article will use the most concise interpretation to help you master the core knowledge of communication infrastructure.
1. Essential Difference: Technology Hierarchy from Micro to System

Fiber Optic

Material Composition: Ultra-pure glass/plastic fiber (diameter ≈ 1/10 of human hair)

Core Function: Ultra-high-speed data transmission through optical pulses (theoretical speed reaches 70% of the speed of light)

Technical Indicators: Single-mode/multi-mode classification determines the transmission distance (2km~100+km)
Optical Cable

Structural Design: Integrated multiple optical fibers + protective layer (common 4~144 core configuration).

Engineering Characteristics: Triple protection system of tensile steel core/water-blocking gel/metal armor.

Environmental Adaptation: 20+ international certification specifications such as indoor/outdoor/undersea.

2. Application Scenario Comparison Table
Scenario Fiber Selection Optical cable type
Data center short distance transmission Multimode OM4 fiber Light branch jumper cable
5G base station long-distance connection Single-mode G.652.D optical fiber Rodent-resistant armored fiber optic cable
Transoceanic Communications Ultra-low loss optical fiber Double-layer steel wire deep-sea optical cable
3. Guide to avoid pitfalls in purchase
Common misunderstandings about optical fiber:
▶ "The more cores, the better" → The actual number of switch ports must be matched
▶ "The loss value is only based on the theoretical value" → The fusion process affects the actual attenuation by more than 30%
4.Highlights of AOPTKE FIBER solutions

Technical tips
When the device displays "optical signal loss":

Check the cleanliness of the optical cable connector (90% of faults are caused by dust pollution).

Do not bend <30mm radius (will cause micron-level optical fiber breakage).
