Telecommunications Cable Information

This SAES-T-920 standard prescribes mandatory requirements governing copper conductor telecommunication cable to be used for voice and carrier frequency facilities in outside plant construction.

Important Design Requirements

Based on the information provided, here are some important design requirements for outside plant cable as outlined in the SAES-T-920 standard:

a. Cables with polyethylene sheath and conductor insulation should not be used within buildings or as terminating cable on distributing frames. This requirement is in accordance with Paragraph 3.08 of NFPA 70, the National Electric Code. This is likely to ensure compliance with electrical safety regulations and to prevent potential fire hazards associated with the use of such cables indoors.

b. Filled cables should be specified for all outside plant buried and underground cable uses. This requirement suggests the use of cables that have filling materials within their construction. Filled cables are typically used for enhanced protection against moisture and environmental elements when installed in buried or underground applications.

c. Table 1 (as amended) should be used in selecting cables for inclusion in design documentation. This indicates the use of a specific table, likely provided within the SAES-T-920 standard or its referenced documents, to guide the selection of appropriate cables based on their specifications and characteristics.

Additionally, Section 5.1 of the standard provides a general overview and guidance for the selection of the proper type of cable to be used in normal outside plant construction. It covers different cable types, prevalent issues, and significant considerations to take into account when choosing the appropriate cable for aerial, underground, buried, and submarine applications.

Section 5.1.1.3 specifically refers to Plastic Insulated-Conductor (PIC) cable and directs readers to refer to Section 5.2 for further information on this type of cable. This suggests that additional details and guidelines for PIC cable can be found in Section 5.2 of the SAES-T-920 standard.

For comprehensive and up-to-date information, it is recommended to refer directly to the SAES-T-920 standard documentation provided by Saudi Aramco or consult with the relevant departments or authorities responsible for telecommunication standards and compliance within the organization.

FAQs about SAES-T-920 PDF Download

Q1: What are outside plant cables?

A: Outside plant cables are specially designed cables used in telecommunications and utility networks for outdoor applications. They are used for transmitting data, voice, and power signals between different locations, including aerial, underground, buried, and submarine environments.

Q2: What are the common types of outside plant cables?

A: Common types of outside plant cables include fiber optic cables, copper cables, coaxial cables, and power cables. Fiber optic cables are widely used for high-speed data transmission, while copper cables are used for voice and lower-speed data transmission. Coaxial cables are often used for cable television (CATV) and broadband applications, and power cables are utilized for transmitting electrical power in outdoor environments.

Q3: What is the difference between aerial, underground, and buried outside plant cables?

A: Aerial cables are designed to be installed above ground, typically on utility poles or other support structures. Underground cables are installed beneath the ground surface, either in conduit systems or direct burial. Buried cables are specifically designed for direct burial without the use of conduits.

Q4: What factors should be considered when selecting outside plant cables?

A: Several factors should be considered, including the application requirements, environmental conditions (such as temperature, moisture, and UV exposure), distance and signal transmission requirements, cable capacity, mechanical strength, and future scalability. Compliance with industry standards and regulations is also essential.

Q5: Can outside plant cables be used indoors?

A: In general, outside plant cables are not recommended for indoor use. They are specifically designed to withstand harsh outdoor conditions and may not comply with the fire safety and electrical regulations required for indoor installations. It is important to use cables specifically designed for indoor applications when routing cables within buildings.

Q6: How are outside plant cables protected from environmental factors?

A: Outside plant cables are designed with protective features such as durable outer sheaths, moisture barriers, armor or shielding, and filling compounds to resist water, chemicals, moisture ingress, UV radiation, and physical damage. These protective elements ensure the long-term reliability and performance of the cables in various outdoor conditions.

Q7: Are outside plant cables compatible with existing infrastructure?

A: Yes, outside plant cables are designed to be compatible with existing infrastructure and can be integrated into telecommunications and utility networks. They often have standardized connectors, interfaces, and installation methods to ensure interoperability with existing systems and equipment.

Q8: How are outside plant cables installed and maintained?

A: The installation and maintenance of outside plant cables involve various techniques such as aerial cable stringing, underground conduit installation, direct burial, and submarine cable laying. Installation and maintenance processes require specialized tools, equipment, and trained personnel to ensure proper cable routing, termination, splicing, and testing.
