What is the standard frequency range for DOCSIS technology used in broadband services?

The standard frequency range for DOCSIS (Data Over Cable Service Interface Specification) technology used in broadband services spans from 5 MHz to 1 GHz. This range allows for the transmission of both upstream and downstream data over coaxial cable networks.

In this range, the lower portion (5 MHz to around 42 or 65 MHz) is typically used for upstream communications, where data is transmitted from the customer to the service provider. The upper portion of the range (from approximately 50 MHz up to 1 GHz) is utilized for downstream communications, where data is sent from the service provider to the customer. This specification allows for efficient use of bandwidth and supports multiple channels, which can enhance data transfer speeds and overall network performance.

The other options listed do not accurately reflect the established standards for DOCSIS technology. The specified ranges in those options do not encompass the complete and standardized frequency usage required for reliable broadband service delivery as defined by DOCSIS specifications. Thus, the correct choice effectively captures the essential frequency parameters expected in DOCSIS technology implementations.
