CC2 to CC3 Master Set Question and
answer verified to pass
The NESC National Electrical Safety Code requires drop cables to be placed
at what minimum depth?
6 inches.
12 inches.
22 inches.
18 inches. - correct answers 18 inches.
When troubleshooting RFoGRadio frequency over glass and PONPassive
optical network FTTx systems that use longer wavelengths, what is the
common cause of higher losses that should be addressed?
Intermixing multimode and single-mode jumpers.
The reflectivity of optical attenuators.
Transmitter fiber allocations.
Macrobends and microbends are caused by improper bending and pinching of
cables and patch cords. - correct answers Macrobends and microbends are
caused by improper bending and pinching of cables and patch cords.
Who is responsible for compiling the physical document of the restoration
plan?
External contractors hired for restoration work.
An identifiable position or group within an organization.
Any available employee in the organization.
,Customers or users of the network. - correct answers An identifiable position
or group within an organization.
What can happen inside fiber-optic equipment room facilities?
Failures can typically arise at patch panels, in optoelectronic systems, and
due to installation practices.
Card failure and too much or too little optical power are rarely the causes of
total or intermittent failure.
Excessive failure rates on all transmitter and receiver cards should be ignored
and only addressed by a field technician.
Installation-related failure occurs exclusively in electronics shelves and nodes
and has little to do with craftsmanship issues. - correct answers Failures can
typically arise at patch panels, in optoelectronic systems, and due to
installation practices.
How is a restoration posture for a fiber network developed?
All personnel must complete industry-accepted fiber-optic training before any
restoration planning can begin.
First, developing an emergency restoration plan and then having each
organization review its resources.
Creating fiber assignments where all are identified generically and can be
restored in the most accessible order rather than by any prioritizing scheme.
Including the resources required to respond to a significant system outage,
such as documentation, technical skills, and essential troubleshooting and
repair equipment and materials. - correct answers Including the resources
required to respond to a significant system outage, such as documentation,
technical skills, and essential troubleshooting and repair equipment and
materials.
,What is the best way to structure a flowchart of basic restoration activities?
Ensure the permanent repair always precedes the troubleshooting step.
Allow each organization to create a flow diagram to be included in the
restoration plan.
Make a detailed list of all the equipment and required materials.
Diagram the events following an actual fiber interruption. - correct answers
Diagram the events following an actual fiber interruption.
What is true when establishing a timing sequence or communication flow for a
restoration flow chart?
The purpose of sequence time planning is to increase the overall restoration
time.
Restoration sequence time charts are initially based on a vast amount of data.
One person from one department should expand on some essential activity
blocks or groups of blocks.
As experience in emergency restoration deployment is gained through actual
deployments or rehearsals, the sequence time chart becomes more detailed
and realistic. - correct answers As experience in emergency restoration
deployment is gained through actual deployments or rehearsals, the
sequence time chart becomes more detailed and realistic.
After identifying the basic restoration activities, what is the next helpful
restoration planning component?
Describing one best-case scenario that would cause a failure.
Asking how many cables can be repaired simultaneously.
Asking what the time allowance for service restoration is from notification of
the problem to restored service.
, Preparing a planning questionnaire to help provide details of what must
happen to restore a failed fiber-optic network. - correct answers Preparing a
planning questionnaire to help provide details of what must happen to restore
a failed fiber-optic network.
When assigning responsibilities for activities resulting from a fiber interruption,
how should the responsibility within an organization be defined?
Create a separate organization for each activity.
Assign responsibilities to positions within the organization.
The technician is responsible for the restoration crew and splicer readiness
training.
Assign responsibilities to specific individuals. - correct answers Assign
responsibilities to positions within the organization.
What is the best way to plan proficiency training for fiber restoration?
It must be separate from inventory and routine maintenance of restoration
materials and equipment.
Using industry-accepted training courses, which are only required for on-call
technicians.
It should be scheduled no more than once every 18 months, with only some
critical personnel required to attend.
It is often best accomplished by simulating a fiber-optic cable failure. - correct
answers It is often best accomplished by simulating a fiber-optic cable failure.
What visually represents the optical fiber's attenuation characteristics and the
OTDROptical time domain reflectometer setup?
A Fresnel reflection.
