OFC stands for Optical Fiber Cable, which is a type of cable made of glass or plastic fibers that transmit data using light.

• OFC is used for high-speed data transmission over long distances.

• It is commonly used in telecommunications, internet, and cable TV networks.

• OFC is more reliable and has higher bandwidth than traditional copper cables.

• Examples of OFC include single-mode fiber and multi-mode fiber.

• OFC requires speci...read more

Multiplexer is a device that combines multiple signals into one signal. Demultiplexer is a device that separates one signal into multiple signals.

• Multiplexer is also known as MUX.

• It is used to increase the capacity of a communication channel.

• Demultiplexer is also known as DEMUX.

• It is used to route a single input signal to multiple output signals.

• Multiplexer and demultiplexer are commonly used in digital communication s...read more

OTDR stands for Optical Time Domain Reflectometer. It is a device used to test and troubleshoot fiber optic networks.

• OTDR sends a pulse of light into the fiber and measures the time and strength of the reflected signal.

• It can detect faults such as breaks, bends, and splices in the fiber.

• OTDR can also measure the length of the fiber and the attenuation of the signal.

• It is an essential tool for maintaining and repairing ...read more

BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different autonomous systems.

• BGP is an exterior gateway protocol used in large-scale networks.

• It allows routers in different autonomous systems to communicate and exchange routing information.

• BGP uses path vector routing, which takes into account multiple factors to determine the best path for data transmission.

• BGP assigns ...read more

OSPF (Open Shortest Path First) is a routing protocol used in computer networks to determine the best path for data packets to travel.

• OSPF is an interior gateway protocol (IGP) used within a single autonomous system (AS).

• It uses the link-state routing algorithm to calculate the shortest path between routers.

• OSPF divides the network into areas to improve scalability and reduce routing overhead.

• Each area has its own link...read more
