Path to Field Tech I and II (to advance to FT III)

Heat shrink tubing is installed over the fusion-splice to strengthen and protect it. When should the heat shrink be installed on the fiber?

Before stripping the plastic coating from the fiber.

How are optical splitters used in the forward path?

In the forward path, optical splitters are used as passive branching devices that divide an optical signal across multiple output fibers.

What is it about radio frequency over glass (RFoG) that made broadband cable operators envision using it to make a seamless transition from the legacy hybrid fiber/coax (HFC) architecture over to a gigabit-capable passive optical network (GPON) or Ethernet passive optical network (EPON)?

RFoG can operate in parallel with GPON or EPON, which eliminates the need for any downtime during the transition.

What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies?

An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises.

What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once?

Changing the infrastructure all at once would cause too many service disruptions.

Which type of star topology used in a passive optical network (PON) places the PON splitters into fiber access terminal (FAT) located deep in the network and closer to the customer premises than the centralized split?

Distributed star

Which of the following describes a fiber pigtail?

Fiber-optic cable with pre-connectorized ends.

Which element of a passive optical network (PON) uses patch panels?

Optical distribution network (ODN)

Which element of a passive optical network (PON) uses a Bragg grating filter?

Optical line terminal (OLT)

Which of these components is used in a passive optical network (PON)?

Optical splitters
