Jio Network Planning Engineer Interview Questions, Process, and Tips

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 dat...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.

Operating fiber power of OLT refers to the power level at which the Optical Line Terminal is transmitting signals through the fiber optic network.

• The operating fiber power of OLT is typically measured in dBm (decibels referenced to 1 milliwatt).

• It is important to ensure that the fiber power level is within the acceptable range to maintain optimal network performance.

• Monitoring and adjusting the fiber power of OLT may b...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 de...read more

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

Network architecture refers to the layout of the network, including the physical and logical components and their interconnections.

• Network architecture includes components such as routers, switches, firewalls, and servers.

• It also involves the design of protocols, addressing schemes, and security measures.

• Common network architectures include client-server, peer-to-peer, and cloud-based.

• Network architecture can be centra...read more
