Alpha AI Interview Questions and Answers

Gpon technology uses a specific frequency for data transmission.

• Gpon technology uses a downstream frequency of 1490 nm and an upstream frequency of 1310 nm.

• This frequency is used because it allows for high-speed data transmission over long distances.

• The downstream frequency is used for data transmission from the service provider to the customer, while the upstream frequency is used for data transmission from the customer to the service provider.

• The use of these specific freq...read more

Single mode is preferred for its higher bandwidth and longer transmission distance.

• Single mode fibers have a smaller core diameter, allowing for higher bandwidth and longer transmission distances.

• Single mode fibers also have lower attenuation, resulting in less signal loss over long distances.

• Single mode fibers are commonly used in long-haul telecommunications and data center applications.

• Multimode fibers, on the other hand, have a larger core diameter and are better suited f...read more

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

• GPON stands for Gigabit Passive Optical Network

• It is a point-to-multipoint access network

• It uses optical splitters to divide a single fiber optic cable into multiple connections

• It provides high-speed internet, TV, and telephone services

• It is widely used in residential and business areas

• GPON is a cost-effective solution for delivering high-bandw...read more

Single mode fiber has a smaller core diameter and allows for higher bandwidth and longer distances than multimode fiber.

• Single mode fiber has a core diameter of 9 microns, while multimode fiber has a core diameter of 50 or 62.5 microns.

• Single mode fiber allows for higher bandwidth and longer distances due to its smaller core diameter and lack of modal dispersion.

• Multimode fiber is less expensive and easier to work with than single mode fiber.

• Single mode fiber is commonly used...read more

Fiber is a type of carbohydrate that cannot be digested by the body.

• Fiber is found in plant-based foods such as fruits, vegetables, whole grains, and legumes.

• There are two types of fiber: soluble and insoluble.

• Soluble fiber dissolves in water and can help lower cholesterol and regulate blood sugar levels.

• Insoluble fiber does not dissolve in water and helps promote regular bowel movements.

• A high fiber diet can help prevent constipation, heart disease, and certain types of canc...read more

The question is comparing ILL (Integrated Local Loop) and Broadband technologies.

• ILL refers to a telecommunications service that provides both voice and data transmission over a single copper wire.

• Broadband refers to a high-speed internet connection that can transmit large amounts of data simultaneously.

• ILL is typically used in areas where broadband infrastructure is limited or unavailable.

• Broadband offers faster speeds and greater bandwidth compared to ILL.

• Examples of broadb...read more
