Your AISG RET Control Cable Supplier

AISG interconnects are circular connectors and cables used in telecommunications to connect antennas, amplifiers, and sensors to controllers, usually base stations, such as in 5G networks and various cell tower equipment. AISG interconnects are named for the Europe-based Antenna Interface Standard Group, which develops the standards that define the physical and electrical characteristics of the AISG connector for RS-485 (AISG C485) (based on IEC 60130-9). The standards also define the communication protocol for the exchange of data between devices.

AISG interconnects are generally used in outdoor applications, thus requiring them to be waterproof (IP67 or better) and able to withstand harsh environmental conditions. The control infrastructure of subunits of antennas and antenna line devices (ALDs), such as RET units (remote electrical tilt), TMAs (tower mounted amplifiers), and various monitoring devices and sensors generally require a different connector layout/cable assembly. Products built using interconnects certified or compliant to the AISG standards ensure the interoperability of equipment from different manufacturers.

Frequency Range
Determine the frequency range required for your specific application. Different cable assemblies are designed to handle different frequency ranges, so it’s important to choose one that meets your needs. Consider both the upper and lower frequency limits to ensure compatibility.

Cable Type
There are various types of RF cables available, such as coaxial cables, triaxial cables, and waveguide cables. Each type has its own characteristics and is suitable for different applications. Consider factors such as signal loss, power handling capability, and flexibility when selecting the cable type.

Connector Type
Choose the appropriate connector type for your application. Common connector types include SMA, N-type, BNC, and TNC. Ensure that the connector type matches the connectors on your equipment or devices to ensure proper compatibility and signal integrity.

Cable Length
Determine the required cable length based on the distance between the equipment or devices that need to be connected. It’s important to choose a cable length that is sufficient for your application without excessive signal loss.

Signal Loss
Consider the signal loss characteristics of the cable assembly. Signal loss, also known as insertion loss, is the reduction in signal strength as it travels through the cable. Lower signal loss is generally preferred, especially for high-frequency applications where signal integrity is critical.

Environmental Considerations
Consider the environmental conditions in which the cable assembly will be used. Factors such as temperature, moisture, and exposure to chemicals or UV radiation can affect the performance and durability of the cable. Choose a cable assembly that is designed to withstand the specific environmental conditions of your application.

Quality and Reliability
Ensure that the cable assembly is of high quality and manufactured by a reputable supplier. Look for cables that meet industry standards and certifications to ensure reliable performance and durability.

Cost
Consider your budget when selecting a cable assembly. While it’s important to choose a high-quality cable, it’s also important to find a balance between cost and performance. Compare prices from different suppliers and consider the overall value provided by the cable assembly.

AISG 1.1: This is the original version of the AISG standard. It defines the electrical and mechanical specifications for connectors, cables, and communication protocols used in controlling and monitoring antenna systems. AISG 1.1 connectors typically have 8 pins and use a circular connector design.

AISG 2.0: This is an updated version of the AISG standard that introduced new features and improvements. AISG 2.0 connectors also have 8 pins and use a circular connector design, but they have enhanced capabilities compared to AISG 1.1. AISG 2.0 connectors are backward compatible with AISG 1.1 connectors.

AISG 3.0: This is the latest version of the AISG standard. AISG 3.0 connectors have 9 pins and use a rectangular connector design. AISG 3.0 introduces additional features and improvements over previous versions, including higher data transfer rates and enhanced functionality.

It is important to ensure compatibility between the AISG connectors and the equipment they are being used with. Different versions of the AISG standard may have different pin configurations, communication protocols, and electrical specifications. It is recommended to consult the documentation and specifications provided by the manufacturer of the AISG connectors and the associated equipment to ensure proper compatibility and functionality.

The maximum cable length for AISG (Antenna Interface Standards Group) connectors depends on several factors, including the specific version of the AISG standard being used and the type of cable being used.
In general, the maximum cable length for AISG connectors is typically specified to be around 100 meters (328 feet). This length is based on the electrical characteristics and signal integrity requirements of the AISG communication protocol.

However, it is important to note that the actual maximum cable length can vary depending on factors such as the cable quality, signal attenuation, and environmental conditions. In some cases, signal repeaters or amplifiers may be required to extend the cable length beyond the standard limit.
