Phuc Gia® – Guidance on Testing Amplifiers in Cable Television Distribution Systems According to QCVN 132:2022/BTTTT

QCVN 132:2022/BTTTT is the Technical Regulation on electrical safety for telecommunications and information technology equipment, including: DECT wireless phones, Desktop computers, Set Top Boxes, Televisions (iDTV), Laptops, and Tablets.

Phuc Gia® – On November 30, 2022, the Ministry of Information and Communications issued Circular No. 24/2022/TT-BTTTT together with QCVN 132:2022/BTTTT, the National Technical Regulation on electrical safety for telecommunications and information technology terminal equipment. Within this regulation, Amplifiers in cable television distribution systems are also included in the list of equipment that must comply with and undergo testing according to this standard.

The electrical safety regulation for telecommunications and information technology terminal equipment, QCVN 132:2022/BTTTT, was compiled based on the IEC 62368-1:2018 standard, covering core electrical safety requirements (fire and explosion protection, electric shock resistance, etc.) and has been in effect since January 1, 2024.

I. SITUATION OF USING AMPLIFIERS IN CABLE TELEVISION DISTRIBUTION SYSTEMS IN VIETNAM

In cable television distribution systems in Vietnam, signal Amplifiers play an important role in improving image and sound quality for users. Cable television signal Amplifiers help enhance signals and minimize attenuation that causes blurring or interference. Simultaneously, they ensure that signals transmitted to terminal devices, such as TVs, remain stable and clear.

In the current context, the role of cable television signal Amplifiers has become extremely important. When put into use, these devices must meet energy efficiency and electrical safety standards, ensuring trust and peace of mind for consumers. This requires importing and manufacturing enterprises to comply with QCVN 132:2022/BTTTT regarding electrical safety for these devices before they are circulated on the market.

II. GUIDELINES FOR TESTING AMPLIFIERS IN CABLE TELEVISION DISTRIBUTION SYSTEMS ACCORDING TO QCVN 132:2022/BTTTT

1. When are enterprises mandatory required to conduct electrical safety testing for these Amplifiers according to QCVN 132:2022/BTTTT?

Pursuant to Circular No. 02/2024/TT-BTTTT, which stipulates the List of Potentially Unsafe Products and Goods under the management responsibility of the Ministry of Information and Communications (Category 2 list), issued on March 29, 2024:

• In Appendix II, it is stipulated that Amplifiers in cable television distribution systems belong to the group of specialized information and communication technology products and goods that must mandatorily perform a declaration of conformity according to QCVN 132:2022/BTTTT.
• The Circular also requires enterprises to mandatorily perform electrical safety testing for this product according to QCVN 132:2022/BTTTT starting from January 1, 2024.

2. Does the Ministry of Information and Communications provide standards for performing electrical safety testing for this equipment?

The Ministry of Information and Communications issued the National Technical Regulation QCVN 132:2022/BTTTT “On Electrical Safety for Telecommunications and Information Technology Terminal Equipment.” The regulation includes General Provisions, Technical Provisions, Management Provisions, Responsibilities of Organizations and Individuals, and Appendices to provide detailed guidance for testing Amplifiers in cable television distribution systems.

3. Which types of cable television signal Amplifiers must undergo testing and declaration of conformity according to this regulation?

According to Circular 02/2024/TT-BTTTT and QCVN 132:2022/BTTTT, Amplifiers in cable television distribution systems within the mandatory scope are: “Equipment with a signal amplification function used in cable television networks (digital wired systems),” having the HS code 8517.62.49.

4. Technical requirements for television signal Amplifiers?

All technical requirements for this equipment are detailed in QCVN 132:2022/BTTTT, including the following provisions:

• General requirements (Classification and safeguards against energy sources; explosion phenomena; Fixation of conductive materials; equipment intended for direct insertion into mains socket-outlets; Likelihood of fire or electric shock due to entry of conductive objects; Component requirements such as disconnect devices, Switches, and relays);
• Protection requirements against electricity for persons;
• Protection requirements against electrically-caused fire.

In addition, this product must also perform testing and certification/declaration of conformity procedures according to other current regulations detailed in Circular No. 02/2024/TT-BTTTT.

5. Where to perform electrical safety testing according to QCVN 132:2022/BTTTT?

According to Circular No. 02/2024/TT-BTTTT, Appendix II clearly states: “Test results from domestic or foreign laboratories that have not been designated or recognized, or test results from manufacturers, shall not be used to assess conformity with this technical regulation.”

=> The testing procedures for Amplifiers in cable television distribution systems according to QCVN 132:2022/BTTTT must be performed by a Designated or Recognized testing organization (under Mutual Recognition Agreements – MRA – of the Ministry of Information and Communications).

The Ministry of Information and Communications has designated Phuc Gia Testing Center to perform electrical safety testing for television signal Amplifiers according to QCVN 132:2022/BTTTT (See details here).

6. Electrical safety testing costs according to QCVN 132:2022/BTTTT?

Depending on the listed prices of each laboratory, the testing costs for television signal Amplifiers according to QCVN 132:2022/BTTTT at Phuc Gia have been listed at: Phuc Gia Lab Testing Quotation.

7. Electrical safety testing time for Amplifiers in cable television distribution systems

The testing time will depend on the specific unit where you wish to conduct the tests.

However, Phuc Gia always provides customers with the best support regarding testing time; therefore, the estimated testing duration for this equipment according to QCVN 132:2022/BTTTT is approximately 15-17 days per model (including weekends and holidays, as Phuc Gia arranges additional personnel and overtime to maximize testing capacity).
