Q

What is a crossover cable?

A

You start with 568B on one end and then switch out pins 12 and three and six on the other end. so you have your transmit and receive pins in a different place When you create that crossover cable, essentially your orange pair and green pair swaps places aka 568A

Q

Multi-Mode Fiber(MMF)

A

Tailored for shorter distances because it has a larger fiber core size that ranges from 50 to 100 µm(microns)

23
Q

What color of cable would a Single-Mode Fiber (SMF)

A

Yellow Sheath

24
Q

What color would a Multi-Mode Fiber (MMF) be

A

Aqua blue or orange sheath

25
Subscriber Connector(SC)
Known for its square shape and push pool design that offers a secure and simple connection mechanism
26
Lucent Connector (LC)
Distinguished by a compact size that utilizes a push pull mechanism similar to the SC but in a much smaller form factor
27
Straight Tip Connector(ST)
Recognizable by its round shape and twist-lock mechanism that offers a robust and reliable connector type for use in networks
28
Mechanical Transfer Register Jack (MTRJ)
It is a small, rectangular design in houses, both the transmit and receive fibers in a single connector
29
Multi Fiber Push On connector(MPO)
Designed to accommodate multiple fibers in a single connector to significantly increase the capacity and flexibility of the fiber networks
30
Back Reflection
Back reflection in fiber optics occurs when light reflects off connectors and returns to the source, degrading the signal by interfering with the outgoing light.
31
Physical Contact
Provide the least effect of reduction in back reflection
32
Ultra Physical Contact (UPC)
Ultra Physical Contact(UPC) is an updated in better version of the older Physical Contact(PC) style polish
33
Angled Physical Contact (APC)
Angled polished connectors are often used in long haul fiber installations
34
Transceiver
Generalized term for any device that can both transmit and receive data
35
Fiber Channel (FC)
High speed network technology primarily used to connect computer data storage to servers in storage area networks
36
Small Form Factor Pluggable (SFP)
It’s hot pluggable and it’s a transceiver that supports up to 4.25 GB per second speed
37
Small Form Factor Pluggable Plus (SFP+)
It’s four times faster than a Small Form Factor Pluggable and is still a transceiver and hot pluggable w/ 16 Gbps of speed
38
Quad Small Form Factor Pluggable (QSFP)
Just like the SFP in the SFP plus, 10 times faster than an SFP and 2 1/2 times faster than SFP plus
39
Quad Small Form Factor Pluggable Plus(QSFP+)
Slightly faster than the QSFP
40
Quad Small Form Factor Pluggable 28(QSFP28)
Similar to the rest just transmits 100 Gbps
41
Quad Small Form Factor Pluggable 56 (QSFP56)
Same as the QSFP28 just w times faster at 200 Gbps
42
Cable Distribution Systems
Structured layout and organization of the network media to insured efficient, reliable data communication
43
Demarcation point
Location at which the Internet service providers connections, and the network infrastructure and cabling begin
44
Main distribution frame(MDF)
Serves as the main starting point for all interior cabling that will be distributed throughout the facility
45
Backbone switch is where…
The network connects
46
Cable tray
Unit or assembly of units that form a rigid structural system to secure the cables and raceways used by the cables as they go across the building
47
Racks
Designed to hold various devices, like switches, routers, patch panels, and servers to facilitate efficient space management and easy access for ongoing network maintenance
48
Two – post rack
Designed with two vertical posts and is used for lighter equipment or for patch panels and network cabling telecommunications setups
49
Four – post rack
Design with four vertical posts and offers enhanced stability and support that makes it ideal for heavier equipment
50
Wall – mounted rack
Space – saving solution used for smaller network equipment and is the four environments with limited floor space or for housing peripheral network components
51
Four counter rack/rack enclosure
Fully enclosed rack with size, doors, and a top that offers a secure and protected environment for high value equipment
52
Patch panel
Device or unit featuring a number of jacks for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient in flexible manner
53
110 block
Type of punch down block for both Voice and data applications that rely on cat five or newer copper based networks
54
Fiber distribution panel
Uses fiber connectors, like SC, LC, ST, or MTRJ to make connections
