Ethernet standards Flashcards
(39 cards)
What is the ethernet standard for “Fast Ethernet”
100BaseTX
Generally, what is the distance range for MMF
33-400m
What is the range and cabling used in 100BASEFX?
2km (with repeaters), Fiber OM1
What cabling does 100BaseSX use
OM1, 2
True or false: 1000baseT and later nics could handle full duplex
True
Does full duplex add speed or bandwidth to a network?
Bandwidth. With duplexing, one road of cars going 60mph becomes two roads going 60mph
What are SFF connectors
A new series of connectors made after Snap Twist and Snap Connect because they were too big. The new connectors are LC and MTRJ.
What do UPC and APC fiber mean.
These refer to how the fiber connectors touch one another inside the device it’s plugged into. Different versions have different benefits.
Ultra physical contact - Rounded
Angles physical contact- Angled, predominant
You see a fiber connector called “SC/APC” what does it mean
Snap Connector, Angled Physical Contact
What are the three 1000base versions
T, SX and LX
When it comes to 100 and 1000 base standards, what does the T and X mean in the names?
T implies UTP, X implies fiber is used.
What is the fiber type used for 1000BaseSX and the distance it can reach
MMF, 500m
What is the length of 1000BaseLX cabling and what type is it
Single mode OS1 or 2 fiber at 5km (5000m)
True or false: The faster the connection must be, the shorter the range of your cabling will become
True, because the speed drops off
What is a media converter?
It changes the method of data travel when leaving your network, allowing it to connect to other types. For example, UTP to fiber.
When referring to fiber nm, what does it mean?
Nano meters is a measurement used to measure the length of a single wave traveling through a fiber cable. Longer waves go further.
What is a GBIC transceiver?
A gigabit interface converter transceiver will convert the signal going into a device from one type to another. MMF>SMF, UTP>Fiber, etc. In other words, it enables communication between device and cable.
What is a SFP
A small formfactor pluggable is a small version of a transceiver.
What’s the difference between a media converter and a SFP/Transceiver?
A media converter converts an outgoing connection on your network
A transceiver allows a cable and specific device to communicate by converting the signal.
What is a BiDi transceiver?
A Bidirectional transceiver removes the need for two fiber cables (one to send and one to receive) by sending both signals over the same piece of fiber.
What is a QSFP+
An SFP that can do 40gbps
When it comes to 10G networks, what do the xR and xW nomenclature imply?
R is for LAN purposes, W is for WAN purposes.
What are the three types of 10G standards?
S, L and E. Short, Long and Extra.
What is the cable length, type and nm width of 10GBaseSR and SW
33-500m over MMF with 850nm wavelengths
