GPON Network: Transmission Equipment

BEG.

GPON stands for Gigabit Passive Optical Network, which is a fiber optic access network that uses passive splitters to divide an optical signal among multiple users. The GPON network consists of several pieces of transmission equipment, including:

1. OLT (Optical Line Terminal): The OLT is the central component of the GPON network that connects the service provider's network to the subscriber's premises. It converts electrical signals from the service provider's network into optical signals that are transmitted over the fiber optic network. The OLT is responsible for managing the transmission of data to and from the ONTs.

2. Splitter: A splitter is a passive optical device that divides a single optical signal into multiple signals, allowing a single fiber to serve multiple subscribers. Splitters are used to connect the OLT to multiple ONTs, typically serving 32 or 64 subscribers per splitter.

3. ONT (Optical Network Terminal): The ONT is the device that is installed at the subscriber's premises and is responsible for converting the optical signal back into an electrical signal that can be used by the subscriber's devices. The ONT typically includes one or more Ethernet ports for connecting to the subscriber's router or other network devices.

Therefore, the correct answers to this question are B (splitter), E (OLT), and G (ONT). The other options listed (A, C, D, and F) are not components of the GPON network. ROADM stands for Reconfigurable Optical Add-Drop Multiplexer and is used in Wavelength Division Multiplexing (WDM) networks. OA and OADM are not standard components of a GPON network, and repeaters are not used in passive optical networks like GPON.
