mode fiber. Maximum cable length up to 10 km.

17
Q

define 10GBASE-SR/10GBASE-SW

A

10 GbE standard using 850-nm
multimode fiber. Maximum cable length up to 300 m.

18
Q

define 10GBASE-T

A

A 10 GbE standard designed to run on Cat 6a UTP cabling.
Maximum cable length of 100 m.

19
Q

Define 40 Gigabit Ethernet (40 GbE).
Which types of optical cable does it use?
What do the transceivers use?

A

runs at 40 Gbps, primarily used in switch-to-switch trunks and data center servers. 40 GbE
can use either single-mode fiber or OM3 (or greater) multimode fiber.
Transceivers use the quad small form-factor pluggable plus (QSFP+) port.

20
Q

what is 66 block

A

Patch panel used in telephone networks; displaced by 110 blocks
in networking.

21
Q

define 100BASE-FX:
what type of signaling does it use?
what is maximum cable length?
What kind of cable does it use?

A

designed to run on fiber-optic cabling.
Runs at 100 Mbps and uses baseband signaling.
Maximum cable length is 400 m for half-duplex and 2 km for full-duplex.

22
Q

100BASE-T:
what cable does it run on and how many does it require to run?
What speeds?
What signaling?

A

An Ethernet LAN designed to run on UTP cabling
Runs at 100 Mbps
uses baseband signaling
uses two pairs of wires on Cat 5 or better cabling.

23
Q

What is 100BASE-TX?

A

The technically accurate but little-used name for 100BASE-
T.

24
Q

Define 100 Gigabit Ethernet (100 GbE):
What speed does it run at and what is it primarily used for?
What type of modes can it employ?
What is the typical connector and what are the channels?

A

Ethernet designation that runs at 100Gbps
primarily implemented in backbones and machine-to-machine connections.
Employs both MMF and SMF with various connectors. A
typical connector, the QSFP28, has four 25 Gb channels.
