Optical fiber is a thin, flexible, transparent fiber made of glass or plastic that can transmit light signals over long distances.

• Optical fiber is used for high-speed data transmission and telecommunications.

• It works by transmitting light signals through the fiber, which bounce off the walls of the fiber and travel to the other end.

• Optical fiber is more efficient than traditional copper wire because it can transmit data over longer distances without losing signal strength.

• It ...read more

Major types of OLT include GPON OLT, EPON OLT, XG-PON OLT, and 10G-EPON OLT.

• GPON OLT (Gigabit Passive Optical Network OLT)

• EPON OLT (Ethernet Passive Optical Network OLT)

• XG-PON OLT (10 Gigabit-capable Passive Optical Network OLT)

• 10G-EPON OLT (10 Gigabit Ethernet Passive Optical Network OLT)

GPON stands for Gigabit Passive Optical Network, a technology used in telecommunications for delivering high-speed internet access.

• GPON is a type of fiber optic communication technology that uses passive splitters to allow a single optical fiber to serve multiple premises.

• It provides higher bandwidth and efficiency compared to traditional copper-based networks.

• GPON is commonly used by telecommunications companies to deliver internet, TV, and phone services to residential and ...read more

STP stands for Spanning Tree Protocol. It is a network protocol used to prevent loops in Ethernet networks.

• STP is used to create a loop-free logical topology in a network.

• It works by selecting a root bridge and calculating the shortest path to reach each network segment.

• STP uses Bridge Protocol Data Units (BPDU) to exchange information between switches.

• It identifies and blocks redundant paths to avoid broadcast storms and network congestion.

• STP operates at the Data Link Layer...read more

Fiber losses for fiber splitter are insertion loss, excess loss, and polarization dependent loss.

• Insertion loss is the loss of signal power when light passes through the splitter.

• Excess loss is the additional loss due to imperfections in the splitter.

• Polarization dependent loss is the loss that varies with the polarization state of the light.

• Example: Insertion loss of a 1x2 splitter is typically around 3.5 dB.

VRRP (Virtual Router Redundancy Protocol) is a network protocol that provides automatic failover for routers in a network.

• VRRP allows multiple routers to work together as a virtual router, providing redundancy and high availability.

• It uses a virtual IP address that can be shared among the routers, with one router acting as the master and others as backups.

• If the master router fails, one of the backup routers takes over the virtual IP address and becomes the new master.

• VRRP op...read more

• GPON stands for Gigabit Passive Optical Network

• Download speed of GPON is typically around 2.488 Gbps

• Upload speed of GPON is typically around 1.244 Gbps

• GPON technology uses optical fiber to deliver high-speed internet access

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven layers.

• The OSI model is used to understand and describe how different network protocols and technologies interact with each other.

• Each layer in the OSI model has a specific function and communicates with the layers above and below it.

• The seven layers of the OSI model are: Physical, Data Link, Network, Transport, Session, Presentation, and...read more
