The particular values depend mainly on the physical configuration and the type of material used in the transmission line.

Travel time depends on the values of the four fundamental properties of the transmission line.

The property of a circuit that causes a counter voltage to be induced in the circuit by a change of current in the circuit.

Resistance increases as the diameter of the wire decreases and as the frequency of the transmitted wave increases.

A mismatch in impedance between equipment and line.

Maximum, instantaneous deviations from the average phase of the signal.

They must be injected at angles that fall within the acceptance cone.

(1) PIN diodes.

(2) APD.

The cable has a central core with one or more glass or plastic fibers. The core is surrounded by a glass or plastic coating called the cladding. A jacket made of plastic or some other hard material is then used to protect the cable.

(1) Multimode step-index.

(2) Multimode graded-index.

(3) Single mode.

Absorption loss is caused by the presence in the fiber of impurities such as iron, copper, nickel, and cobalt.

To accurately add, remove or fault isolate circuits.

(1) Jumper rings.

(2) Fanning strips.

(1) Electrical.

(2) Mechanical.
(3) Hand wrap.

With an unwrapping tool, longnose pliers, or by hand.

(1) They require less space.

(2) Easy access to connector blocks.

(3) The ease at which wires can be terminated.

(1) Looping termination.

(2) Ending termination.

Four conductors colored blue, orange, green, or brown, are the "ring" conductors. Four are colore white, which are the "tip" conductors. Each tip coductor is marked with either a hand of its ring-mate's color at regular intervals, or has a stripe of its ring-mate's color running its length.

(1) A straight-through.

(2) Crossover.

(3) Rollover cable.

This is the standard two- or four-conductor telephone connector used to connect telephone handsets to telephone outlets.

Thisis the standard TP connector used for data networking.

(1) EIA/TIA 568A.

(2) 568B.

(1) Strip away about 1.25-inches of outer jacket.

(2) Untwist wire pairs; avoid untwisting at end.

(3) Arrange wires in flat row in order that matches pinout pattern for cable purpose.

(4) Use wire-cutters; trim length of wires to 0.5in.

(5) Insert into RJ-45 plug; ensure remain in pattern.

(6) Use RJ-45 crimping tool.

(1) Crimp-on.

(2) Screw-on.

(1) Cut the cable to exactly the length you want the cable to be.

(2) Put the crimp-on sleeve on the cable jacket on the end of the cable you are going to connectorize.

(3) Using your cable stripper, strip about 5/8" of the jacket from the end of the cable.

(4) Trim the braided shielding so that 7/32" of braid is showing.

(5) Strip the inner protective plastic insulation around the center conductor so that 7/16" of plastic is showing.

(6)  Insert the center conductor into the center pin of the connector.

(7) Push the connector unil the center pin clicks into the connector.

(8) Slide the ferule along the sleeve down the cable so that it pushes the braided shielding around the barrel of the connector.

(9) Check to see that the connector is securely attached to the end of the cable-you should not be able to move it.

The cable is single mode or multimode and the diameters of the core are cladding.

(1) Cut and strip the cable.

(2) Trim the aramid yarn.

(3) Strip the optical-fiber buffer.

(4) Prepare the epoxy.

(5) Epoxy the connector.

(6) Insert the fiber in the connector.

(7) Dry the epoxy.

(8) Scribe and remove extra fiber.

(9) Polish the tip.

(10) Perform a visual inspection.

(11) Finish.

(1) Number of contacts.

(2) Current per contact.

(3) Voltage.

To handle large contacts needed for high currents and large air gaps needed for high voltage.

(1) Temperature.

(2) Altitude.

(3) Moisture.

(4) Vibration.

Conductor resistance increases with a temperature increase.

The higher the altitude, the less insulation efficiency.

Resilient materials such as polychloroprene or silicone rubber.

Amount of resistance offered to voltages on adjacent contacts.

Prevents mismatching or cross-plugging.

Provides a moisture seal between connector and equipment, and between the insulator and shell.

Protection against moisture.

Under what conditions would you require the use of nonremovable contacts?

(1) Solder.

(2) Crimping.

Place the wire in a crimp pot on the end of a contact and compress the pot with a special tool.

Great flexibility and a wider range of guage settings.

Wire insertion easy to inspect, no temperature or cleanliness problems, and more portable.

State the purpose of a multimeter.

It allows measurement of voltage, current, and resistance.

The one with the lowest resistance to ground unless you can get lower circuit distortion and system noise on the other ground.

Compare your readings with the readings that were recorded in the cable installation test and acceptance data found in the cable records.

Physically inspect the suspected part of the wire path until you locate the impairment.
