Fttx basics conventional
The National Electrical Safety Code requires drop cables to be placed at what minimum depth?
18"
What should be used to cut the fiber drops buffer tube?
A tube cutter
What should be used to remove the protective gel from exposed fibers in drop cable?
An approved alcohol swab
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.
The job of the drop fiber transceiver is to
Convert light to RF and RF to light
What is the best approach to repairing an aerial fiber optic drop cable for fiber to the user (FTTX) applications?
Replace the drop cable
When a pew connectorized fiber is not attached to equipment, what should be attached to help keep it clean?
A dust cap
When should you take the RF reading out of the RF out port of a fiber optic drop transceiver?
After power supplies are connected and powered for the optic transceiver
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.
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
What is one reason why broadband cable operators install a 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 element (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?
Optical splitters
A wavelength optical power meter is most commonly used in
Point to multipoint FTTX installations
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
Once fiber is spliced, the proper way to handle it is by
The heat shrink sleeve that has a steel bar inside it
