Which of the following is a characteristic of GPON technology?

GPON, or Gigabit Passive Optical Network, is recognized for its efficient data transmission capabilities, particularly in a fiber optic network. A defining characteristic of GPON technology is that it utilizes a single downstream channel to deliver high-bandwidth services from the optical line terminal (OLT) to multiple optical network units (ONUs) within a designated area.

Option B suggests multiple downstream channels, which is not accurate for GPON. In fact, GPON employs a point-to-multipoint architecture using a single downstream channel that transmits data to all users. This single-channel provision allows for a more organized and bandwidth-efficient distribution of data to multiple endpoints.

The correct characteristic of GPON technology lies in how it efficiently provides high-speed internet, voice, and video services over its single downstream channel, accommodating a large number of simultaneous users while maintaining quality and performance. Moreover, GPON supports advanced features like dynamic bandwidth allocation and offers high bandwidth efficiency, contrary to the claim that it has low bandwidth efficiency. Additionally, it typically has good compatibility with various systems, rather than being limited in its compatibility with legacy systems.

Understanding the structure of GPON, including its channel utilization and system capabilities, helps clarify its advantages in providing service to multiple end-users efficiently.
