Question 1

In telecommunications, what is 'dark fiber' and why might an enterprise choose to lease it?

Accepted Answer

Installed fiber optic cable that carries no active signal, leased to customers who provide their own optical equipment for full control over capacity and protocols

Answer

Dark fiber gives enterprises or carriers raw fiber they can light with their own DWDM or Ethernet equipment, offering unlimited bandwidth scalability and protocol flexibility.

Question 2

What is 'managed services' in the telecom context and how does it differ from purchasing equipment outright?

Accepted Answer

Managed services means the provider operates and maintains the telecom infrastructure (WAN, UC, security) on the customer's behalf, typically under an OPEX subscription model

Answer

Managed services transfer operational responsibility (monitoring, maintenance, upgrades) to the provider, freeing enterprise customers from managing complex telecom infrastructure while converting CAPEX to predictable OPEX.

Question 3

What is an 'interconnection agreement' between two telecommunications carriers?

Accepted Answer

A contract governing how two carriers exchange traffic, including technical arrangements, routing rules, and financial settlement terms

Answer

Interconnection agreements define how carriers connect their networks, how they route each other's traffic, and how they settle financially for the traffic exchanged (e.g., reciprocal compensation).

Question 4

What is 'universal service' in US telecommunications policy, and which fund supports it?

Accepted Answer

The policy goal of making affordable basic telecommunications services available to all Americans, supported by the FCC's Universal Service Fund (USF)

Answer

Universal service ensures access to telecommunications for rural, low-income, and high-cost areas; the USF collects fees from carriers and distributes subsidies through programs like E-Rate, Lifeline, and Connect America.

Question 5

In project management for telecom deployments, what is a 'critical path'?

Accepted Answer

The sequence of dependent tasks that determines the minimum possible project duration; any delay on the critical path delays the entire project

Answer

The critical path method (CPM) identifies the longest chain of dependent tasks; delaying any critical path task directly extends the project completion date.
