Optical cables play a vital role in modern communication networks, but during use, optical cables may encounter various faults. Understanding the causes of these faults and mastering the corresponding solutions are of great significance for maintaining and ensuring the normal operation of communication networks. This article will introduce the common faults of optical cables and their solutions in detail.
Fiber breakage is one of the common faults of optical cables, usually caused by mechanical stress, external force damage or improper operation during installation. Broken optical fiber will cause the signal to be completely interrupted, affecting the quality of communication.
Solution:
Fiber cable splicing: Use a fusion splicer to reconnect the broken optical fiber to ensure the connection quality of the optical fiber.
Protection measures: Strengthen the protection of optical cables to avoid mechanical stress and external force damage. During the laying and maintenance of optical cables, pay attention to operating specifications to reduce the possibility of optical fiber breakage.
Fiber bending loss refers to the attenuation of the optical signal at the bend when the bending radius of the optical fiber is too small, resulting in a decrease in signal quality.
Solution:
Reasonably design the laying path: During the laying of optical cables, try to avoid excessive bending and ensure that the bending radius of the optical fiber meets the technical standards.
Use anti-bending optical fiber: Selecting optical fiber with anti-bending performance can effectively reduce bending loss.
The optical cable sheath is the outer protective material of the optical cable, which is used to protect the optical fiber from the influence of the external environment. Damage to the sheath will cause the optical fiber to be exposed to the outside, increasing the risk of optical fiber damage.
Solution:
Regular inspection: Regularly check the integrity of the optical cable sheath, and repair or replace it in time if damage is found.
Add protective facilities: During the laying of optical cables, protective facilities such as optical cable protection tubes or optical cable bridges can be added to enhance the protection of optical cables.
OTDR is a commonly used optical cable fault detection equipment. It can send optical pulse signals to measure the reflection and scattering of optical signals in optical fibers, thereby determining the fault location and type of optical cables.
The optical power meter is used to measure the optical power value of the optical fiber port. By comparing the changes in the optical power value, it can be determined whether the optical cable has a fault.
The optical fiber microscope is used to observe the cleanliness and end face damage of the optical fiber end face, helping to identify the fault of the optical fiber end face.
During the laying of optical cables, the operation should be strictly in accordance with the specifications to avoid excessive bending, stretching or mechanical damage.
During the laying and maintenance of optical cables, the protection measures of optical cables should be strengthened to reduce the damage to the optical cables by external factors.
Maintain and inspect the optical cables regularly to detect and deal with potential faults in time to ensure the long-term and reliable operation of the optical cables.
