Armored optical cable is an optical cable with a protective "armor" (stainless steel armor tube) wrapped around the fiber core. This stainless steel armor tube can effectively protect the fiber core from animal bites, moisture erosion or other damage. Simply put, armored optical cables not only have the characteristics of ordinary optical cables, but also provide additional protection for optical fibers, making them stronger, more reliable and durable. Today, armored optical cables are the best choice for campus networks, data centers and industrial applications.
The structure of armored optical cable
1. Fiber Core: The core fiber is the part that transmits data signals. It usually consists of one or more optical fibers, each of which consists of a core and a cladding. Core fiber is used to transmit optical signals from one end to the other.
2. Filler (Buffer Material): The filler is located between the core fiber and the metal armor, filling the gap and providing protection and support. It can be a loose polymer material or a gel-like substance that coats the fiber.
3. Metal Armor: Metal armor is a key part of armored optical cables, which provides mechanical strength and protective performance. Metal armor is usually made from spiral or corrugated metal wire, such as steel or aluminum wire. It can resist stresses such as pressure, tension and impact in the external environment, and protect the internal optical fiber from damage.
4. Outer Jacket: The outer jacket is the outermost protective layer of the armored optical cable. It is usually made of materials with good wear-resistant, insulating and waterproof properties, such as PVC (polyvinyl chloride) or LSZH (low smoke halogen-free). The outer jacket protects the fiber optic cable from damage from the external environment and provides an additional layer of protection.
Characteristics of armored optical cable:
1. Mechanical protection: Armored optical cable has high mechanical strength and durability, and can withstand external pressure, tension and impact stress. This allows armored cables to provide better protection against fiber damage in harsh environmental conditions, such as outdoors, underground or industrial environments.
2. Anti-external interference: The metal armor layer of the armored optical cable can effectively resist electromagnetic interference and radio frequency interference. This means that even in environments with a large number of power lines, high-voltage cables or other sources of interference, armored optical cables can still maintain high signal integrity and data transmission quality.
3. Adapt to long-distance transmission: Because armored optical cables have high mechanical strength and protective properties, they are usually used in situations where long-distance optical fiber transmission is required. Armored optical cable can effectively reduce the attenuation and loss of optical signals, thereby ensuring the stability and reliability of signals during long-distance transmission.
4. Cope with special environments: In certain application scenarios, such as undersea communications, oil fields, mines, or other harsh environments, the use of armored optical cables can provide better protection for optical fibers and enable them to adapt to extreme temperatures, humidity, and chemicals. and other special conditions.
