Q

Four out of the five copper standards have a distance limit of 100 meters. (True/False)

A

True

22
Q

What copper standard has a distance limit much shorter than 100 meters?

A

40GBASE-T

23
Q

What is 40GBASE-T’s distance limit?

A

30 meters

24
Q

RJ-45s are not used for connectors in all copper standards. (True/False)

A

False; All five copper standards use RJ-45 connectors

25
Q

What is the first and earliest fiber optic standard you need to know?

A

100BASE-FX

26
Q

What is 100BASE-FX’s distance limit?

A

2 kilometers

27
Q

What is 100BASE-FX’s node limit?

A

1,024 nodes

28
Q

What cabling does 100BASE-FX use?

A

MMF (generally OM1)

29
Q

What two connectors does 100BASE-FX use?

A

ST or SC connectors

30
Q

What standard is the short-distance LED alternative to 100BASE-FX?

A

100BASE-SX

31
Q

What has a longer distance range, 100BASE-FX or 100BASE-SX?

A

100BASE-FX

32
Q

What three connectors can 100BASE-SX use?

A

ST, SC, or LC

33
Q

What cabling and wavelength measurements pertain to 100BASE-SX?

A

OM1/OM2 @ 850 nm

34
Q

The third fiber optic standard has the same name as the second except it is running at a 1 Gbps speed. (True/False)

A

True; It is 1000BASE-SX instead of 100BASE-SX

35
Q

What is the wavelength measurement of 1000BASE-SX?

A

850 nm

36
Q

What cabling does the 1000BASE-SX use?

A

OM2 or better MMF (OM1 works for short distances)

37
Q
A
38
Q

What connectors does the 1000BASE-SX use?

A

Mostly LC but can vary

39
Q

What’s the 1000BASE-SX’s distance range?

A

220-500 meters

40
Q

If the first GB fiber optic standard is 1000BASE-SX (short wavelength, hence the “S”), what is the other GB fiber standard?

A

1000BASE-LX

41
Q

What connectors does the 1000BASE-LX use?

A

Varies, but commonly LC or SC

42
Q

What is the 1000BASE-LX’s cabling and wavelength measurement?

A

OS1 or OS2 SMF; 1300 nm

43
Q

What is the 1000BASE-LX’s distance range?

A

5 kilometers

44
Q

Having an “L” in a standard such as “…BASE-L_” means SMF is used as cabling.

A

True; Remember “L” means long wavelength, which is SMF because it shoots long-distance lasers

45
Q

What do “R” and “W” each stand for in the underscore’s place in something such as “…BASE-L_”?

A

R = LAN; W = WAN

46
Q

What are the two 10 Gb fiber optic standards you need to know?

A

10GBASE-SR & 10GBASE-LR

47
Q

What is a good rule of thumb for remembering what “S” and “L” mean in standard names?

A

If it is “S”, it should not correlate to another “S”, so it is MMF. “L” means long, so it is SMF because SMF shoots long-distance lasers

48
Q

What is the wavelength measurement and distance range of 10GBASE-SR?

A

850 nm; 33-400 meters

49
Q

What is the fiber type and physical layer signaling of 10GBASE-SR? (Hint: it’s all in the name)

A

MMF; LAN

50
Q

What is the fiber type and physical layer signaling of 10GBASE-LR?

A

SMF; LAN

51
Q

What is the wavelength measurement and distance range of 10GBASE-LR?

A

1310 nm; 10 kilometers
