FAQs 6

What does a 42 volt power supply mean?

42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected. It can be seen that when the length more than 120m in the 4G system and the length more than 70m in the 5G system, the ICT equipment will be off because the low voltage protection of the power supply system.

What voltage does a DSL power system supply?

The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).

What is a preferred power supply architecture for DSL applications?

A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
