Consolidation Points- Location where disparate consignments are collected to be shipped together to their final destination. 9. Crimpers- To press or pinch into small regular folds or ridges 10. Fish Tape- is a tool used by electricians to route new wiring through walls and electrical conduit. 11.
Andrey Borsch NT1310 Unit 4 Exercise 1 4-18-14 Cabling - Definitions Horizontal Cable - The cabling between and including the telecommunications outlet and the horizontal cross-connect. Horizontal cabling is considered the permanent portion of a link; may also be called horizontal wiring. Backbone Cable - The physical/electrical interconnections between telecommunications rooms and equipment rooms Patch Cord - Any flexible piece of cable that connects one network device to the main cable run or to a patch panel that in turn connects to the main cable run. Used for interconnecting circuits on a patch panel or cross-connect. Patch cables are short distance, usually have connectors preinstalled on both ends, are used to connect equipment, and are generally between 3 and 6 meters long.
Which of the following is the most likely reason why EMI from one wire does not affect the electrical behavior of another wire inside the same cable? b 7. Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10BASE-T and 100BASE-T? (Choose two answers.) a,b 8.
NT1310 Unit 6 Assignment 1: Cable Tester The three cable testers I would choose would be the optical loss test set and test kit, the Time-Domain Reflectometers (TDR), and the tone generators. The Optical Loss Test Sets and Test Kits is a useful tool in a lab or for testing patch cables, two separate devices would be needed to test a permanently installed link because you have to connect the light source to one end of the cable and the power meter to the other. You need both an optical power meter and a light source in order to properly install and troubleshoot a fiber-optic network, and you can usually save a good deal of money and effort by purchasing the two together. You will thus be sure to purchase units that both support the wavelengths and power levels you need and that are calibrated for use together. You can purchase the devices together as a single combination unit called an optical loss test set (OLTS) or as separate units in a fiber-optic test kit.
If they don't line up, pull them out and line up. Do this carefully, as it's the last step before crimping on the connector. Step 8: Carefully insert the connector and cable into the crimping tool, which has two dies that will press into the connector, and push the pins in the connector into the conductors inside the connector. Now the installation is done. After the whole installation, you should check to ensure all conductors are making contact and that all pins have been crimped into their respective conductors.
Master It – The customer wants to ensure capability to operate 10Gbase-T What cable would you recommend to offer the best shielding performance? I would recommend the screened shielded twisted pair (f/FTP and S/FTP) Determine the uses of pleum-and-riser-rate cabling. Plenum cable – Cable whose flammable and smoke characteristics allow it to be routed in in air handling space between the wall, under structured floors, and above drop ceilings, without being enclosed in a concuit. Riser Cable- A type of cable to be used in vertical building shafts Such as telecommunications and utility
The optical time-domain reflectometer is the fiber-optic equivalent of the TDR. This tester transmits a calibrated signal pulse over the cable to be tested and monitors the signal that returns back to the unit. Unlike TDR however OTDR measures the signal returned by backscatter, phenomenon that affects all fiber-optic cable. Due to splicing and attaching connectors to fiber-optic cables the best way to inspect cleaved fiber ends and polished connection ferrules is with a microscope. The microscope is designed to hold cables and connectors in precisely the correct position for examination enabling you to detect dirty, scratched, or cracked connectors and ensure that cables are cleaved properly in preparation for splicing.
3) Engineering and isolating controls - The provision or mechanical aides, barriers, machine guarding, ventilation or insulation to isolate a hazard from workers. For example: Using antiglare screens on computers. 4) Establishing policies, procedures and work practices - Designed to reduce a workers exposure to a risk can also include the provision of specific training & supervision. For example: Increasing job variety and introducing job rotation. 5) Personal Protective Equipment (PPE) - PPE must be provided and maintained by the employer and the employer must also provide training for workers required to use it.
Landline phones is a phone that uses a solid medium telephone line such as metal wire or fiber optic cable for transmission. Modern lines may run underground, and may carry analog or digital signals to the exchange, or may have a device that converts the analog signal to digital for transmission on a carrier system. SMS/Text Messaging (Short Message Service) an electronic message between two or more mobile phones, or fixed or portable device over a phone network. A service component of phone, Web, or mobile communications systems. Data application.
Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol. R1 and R2 can ping the directly connected serial interface of their neighbor, but they cannot form an EIGRP neighbor adjacency. What action should be taken to solve this problem? Configure both routers with the same EIGRP process
