SFP stands for Small Form-factor Pluggable, a compact transceiver used in networking devices. Losses in optical fiber refer to the reduction in signal strength as light travels through the fiber.

• SFP is a hot-swappable transceiver used in networking equipment to transmit and receive data over optical fiber or copper cables.

• Losses in optical fiber can occur due to factors like bending, splicing, and impurities in the fib...read more

Optical Time Domain Reflectometer

• OTDR stands for Optical Time Domain Reflectometer

• It is a device used to test the integrity of fiber optic cables

• OTDR sends a pulse of light down the fiber and measures the reflections to determine the quality of the cable

• It is commonly used in network field engineering for troubleshooting and maintenance

The colour code of twisted pair cables is used to identify the different pairs of wires within the cable.

• The most common colour code for twisted pair cables is the TIA/EIA 568 standard, which uses the following colours: white/blue, blue, white/orange, orange, white/green, green, white/brown, brown.

• The colour code helps technicians easily identify and match the correct pairs of wires when terminating the cable.

• Using the...read more

Virtual memory is a memory management technique that allows a computer to compensate for physical memory shortages by temporarily transferring data from RAM to disk storage.

• Virtual memory allows a computer to run programs that require more memory than physically available

• It creates an illusion of a larger memory space by using disk space as an extension of RAM

• Data is swapped between RAM and disk storage based on usage ...read more
