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
Q

Subscriber Connector(SC)

A

Known for its square shape and push pool design that offers a secure and simple connection mechanism

26
Q

Lucent Connector (LC)

A

Distinguished by a compact size that utilizes a push pull mechanism similar to the SC but in a much smaller form factor

27
Q

Straight Tip Connector(ST)

A

Recognizable by its round shape and twist-lock mechanism that offers a robust and reliable connector type for use in networks

28
Q

Mechanical Transfer Register Jack (MTRJ)

A

It is a small, rectangular design in houses, both the transmit and receive fibers in a single connector

29
Q

Multi Fiber Push On connector(MPO)

A

Designed to accommodate multiple fibers in a single connector to significantly increase the capacity and flexibility of the fiber networks

30
Q

Back Reflection

A

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
Q

Physical Contact

A

Provide the least effect of reduction in back reflection

32
Q

Ultra Physical Contact (UPC)

A

Ultra Physical Contact(UPC) is an updated in better version of the older Physical Contact(PC) style polish

33
Q

Angled Physical Contact (APC)

A

Angled polished connectors are often used in long haul fiber installations

34
Q

Transceiver

A

Generalized term for any device that can both transmit and receive data

35
Q

Fiber Channel (FC)

A

High speed network technology primarily used to connect computer data storage to servers in storage area networks

36
Q

Small Form Factor Pluggable (SFP)

A

It’s hot pluggable and it’s a transceiver that supports up to 4.25 GB per second speed

37
Q

Small Form Factor Pluggable Plus (SFP+)

A

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
Q

Quad Small Form Factor Pluggable (QSFP)

A

Just like the SFP in the SFP plus, 10 times faster than an SFP and 2 1/2 times faster than SFP plus

39
Q

Quad Small Form Factor Pluggable Plus(QSFP+)

A

Slightly faster than the QSFP

40
Q

Quad Small Form Factor Pluggable 28(QSFP28)

A

Similar to the rest just transmits 100 Gbps

41
Q

Quad Small Form Factor Pluggable 56 (QSFP56)

A

Same as the QSFP28 just w times faster at 200 Gbps

42
Q

Cable Distribution Systems

A

Structured layout and organization of the network media to insured efficient, reliable data communication

43
Q

Demarcation point

A

Location at which the Internet service providers connections, and the network infrastructure and cabling begin

44
Q

Main distribution frame(MDF)

A

Serves as the main starting point for all interior cabling that will be distributed throughout the facility

45
Q

Backbone switch is where…

A

The network connects

46
Q

Cable tray

A

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
Q

Racks

A

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
Q

Two – post rack

A

Designed with two vertical posts and is used for lighter equipment or for patch panels and network cabling telecommunications setups

49
Q

Four – post rack

A

Design with four vertical posts and offers enhanced stability and support that makes it ideal for heavier equipment

50
Q

Wall – mounted rack

A

Space – saving solution used for smaller network equipment and is the four environments with limited floor space or for housing peripheral network components

51
Q

Four counter rack/rack enclosure

A

Fully enclosed rack with size, doors, and a top that offers a secure and protected environment for high value equipment

52
Q

Patch panel

A

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
Q

110 block

A

Type of punch down block for both Voice and data applications that rely on cat five or newer copper based networks

54
Q

Fiber distribution panel

A

Uses fiber connectors, like SC, LC, ST, or MTRJ to make connections
