What is the expected DC voltage for most Hybrid fiber/coax network equipment?

The expected DC voltage for most Hybrid Fiber/Coax (HFC) network equipment is +24 VDC, ±0.5 V. This voltage level is commonly used to ensure compatibility and efficiency across various HFC devices, including those involved in signal processing and amplification.

The choice of +24 VDC balances the need for adequate power supply while maintaining safety and minimizing energy loss in cable runs. This voltage level is sufficient to drive typical components within HFC networks effectively, such as amplifiers, splitters, and network interfaces.

Additionally, the ±0.5 V range provides a small tolerance that allows for minor fluctuations in voltage during operation, contributing to the reliability and stability of the system. The use of 24 volts also aligns with industry standards, which helps in maintaining uniformity across different manufacturers and products involved in HFC deployments.
