Q

Straight Through Cable (Patch cable)

A

Contains the exact same pinout on both ends of the cable
Ex: 568A -> 568A or 568B -> 568B

  • Used to connect DTE to DCE
  • Connecting unlike devices
  • DTE - “endpoint” devices that connect to a piece of data communications equipment or DCE
  • DCE - includes things like switch, modem, hub, bridge

Q

Crossover Cable

Study These Flashcards
A

Used to connect like/same devices

Swaps the send and receive pin outs
- 568A on 1 end and 568B on the other end

24
Q

For the exam, what cable should be used in connecting switch to switch?

Study These Flashcards
A

Crossover cable

Not unless the switch has MDIX (Medium Dependent Interface Crossover) feature wherein it simulates a crossover cable even if youre using a straight through patch cable

*If a switch doesn’t support MDIX, use crossover cable

25
Color Pin Outs on 568A
Green white, green Orange white, blue Blue white, orange Brown white, brown
26
Plenum Cable
Special Coating used on UTP or STP cable to prevent released of chemicals if there's a fire - Used in ceilings, walls, raised floors, or air ducts - Used in a place where no one can see
27
What is fiber optic cable
Uses light to transmit data through a glass - Immune to EMI since no electricity involved in data transmission - Signal goes in extremely long distance because were using light not unlike copper cables where there's limitation
28
Disadvantage of using fiber
Expensive Difficult to work with since it requires special tools and training - Most businesses only use fiber to connect to their edge switches
29
What is SMF
Small core size Data travels in a single direction Covers longer distances More expensive
30
What is MMF
Used for shorter distance Larger core size Allows multiple modes of travel Covers shorter distance - Up to 2kms or less Less expensive
31
Connectors used on Fiber media
SC ST LC MTRJ
32
SC
33
SC
Subscriber Connector - Stick and Click
34
ST
Straight Tip Connector - Stick and Twist - Commonly used in fiber optic connections in LAN networking applications.
35
LC
Lucent Connector - Love Connector - 2 Cables side to side
36
MTRJ
Mechanical Transfer Register Jack - Small form factor, commonly used
37
What is APC and what uses APC
SC - If the connector is green then it's APC
38
What is UPC and what uses UPC
MTRJ - If connector is blue, it's UPC
39
What is WDM
Combines multiple signals into one signal and sends over a single fiber optic strand using differemt wavelengths of the laser light source
40
What is CWDM
Coarse WDM - up to 18 channels - channel distance is 20nm - speed is up to 10gbps (ethernet), up to 16gbps (Fiber) - used in shorter dostance
41
What is DWDM
Dense WDM - Up to 80 channels - 0.8nm - Up to 8 tbps (100gbps/channel)
42
What really is the difference between a copper and a fiber
Copper has limited distance, usually 100 meters but it's less expensive. Fiber on the other hand is expensive but can cover up to longer distance, immune to emi, more secure.
43
What is a media converter/transceiver
Converts media from one format to another They conduct layer 1 to layer 1 conversion Ex: Fiber to copper, copper to fiber, fiber to coaxial, coaxial to fiber Media converter is a layer 1 device
44
What is half duplex/bidirectional
Can communicate but not at the same time, have to wait for their turn
45
What is full duplex
Devices can communicate both at the same time
46
Types of Transceivers
1. GBIC - standard hot pluggable gigabit ethernet transceiver that can take copper or fiber in as its connector. 2. SFP - Small form-factor pluggable - Smaller module, compact - Up to 4.2GBPS 3. SFP+ - faster version of SFP, up to 16GBPS 4. QSFP - Quad Small form-factor pluggable - Up to 40GBPS 5. QSFP+ - Up to 41.2GBPS **This are all just different type of transceivers that converts light signal from fiber cable to electrical 1 and 0s **This are all used in routers and switches **if you need to change the physical format of your network, you can do that by using media converter/transceiver
47
What is a demarcation point
48
What is a backbone switch
Connects to everything on the network 1 main switch where multiple switches are connected to this main switch (used in large orgs) and this becomes your backbone switch *All the other switches connected to the backbone switch is called edge switches *An edge switch is closer to end users
49
Where is a backbone switch located
On the main distribution frame
50
What is an MDF
Main Distrib Frame - main starting point for your all interior cabling - This is like the trunk of a tree - All the other branches are IDFs (smaller distribution frame)
51
What is an IDF
Contains edge switches, patch panels, edge router, and other associated equipment. - Designed to support the floor and offices nearest to it
52
Types of Punchdown Blocks
66 - older technology, use in old telephone systems and cat3 networks 110 - used for voice and data applications, supports high speed data network for cat5 and above - 110 block is the most common Krone - European alternative to 110 block, only difference is the angles Bix - another proprietary punch down block
53
What is a patch panel
Keeps data center or server room organized by making it easy to move, add, change a cable distrubution - Has 2 side, 1 side is for Rj45 and other side is like a punchdown block **We use patch panel in order to make sure we prevent damaging a switch port which is expensive to replace **We make changes directly on the Patch panel instead of the switch
54
Fiber distribution patch panel
Convert fiber connection from one type to another
55
What is a toner probe
Used to find which port is tied to the patch panel - Used to find breaks in a wire
