How wide is the ODFM?

• A. 48 Mhz
• B. 56 Mhz
• C. 96 Mhz
• D. 128 Mhz

Answer: (C)

The ODFM (Orthogonal Frequency-Division Multiplexing) typically operates with a bandwidth of 96 MHz. This technology allows for the efficient transmission of large amounts of data over a limited bandwidth by dividing the spectrum into multiple narrowband channels. Each channel can carry its own data, and the orthogonal nature of the signal minimizes interference between them.

In many modern digital communication systems, such as those used in cable TV and internet services, 96 MHz is used as a standard bandwidth for downstream data channels. This capacity is sufficient to support high-speed data transmission, enabling a seamless experience for users engaging in activities like streaming video or online gaming. Understanding the correct bandwidth is essential for field technicians, as it directly impacts service delivery and quality assurance.
