the TIA/EIA standard for planning, deploying, and managing the wiring of a large network
568 Commercial Building Telecommunication Cabling
where the central backbone of the network connects to the external provider, such as a local exchange carrier
entrance facility
this provides the main cross-connection point where horizontal cross-connects for a facility are terminated. this connects to the telco closets via the backbone wiring
equipment room
this copper cable standard is rated at 10 Mbps and 16 MHz and was used in the original 10 Mbps Ethernet networks. It is sometimes still used for telephone cabling.
CAT 3
this copper cable standard is rated up to 100 Mbps and 100 MHz, and is used for Ethernet cabling
CAT 5
this copper cable standard is rated UP TO 1 Gbps, and is used for Gigabit Ethernet networks
CAT 5e
this copper cable standard is rated AT 1 Gbps and operates a frequency of up to 250 MHz. it is used for true gigabit ethernet networks
CAT 6
this copper cable standard is rated at 10 Gbps but operates at a frequency of up to 500 MHz

a cable used to connect devices to hubs and switches in which all the wires run straight through
straight-through cable
a cable used to connect devices to hubs and switches in which wires 1 and 3, and 2 and 6 are crossed
crossover cable
this coax connector locks by a half twist
BNC
this connector screws in with a nut (TV connector)
F-type
this fiber connector uses a half-twist bayonet type of lock
ST
this is a fiber push-pull connector
SC
this fiber connector has a flange on the top like a RJ45
LC
this is a popular connector for two fiber in a very small form factor
MT-RJ
this type of fiber-optic cable transmits many beams of light through the cable, thus weakening the signal and reducing the distance and speed at which it travels
multimode fiber
this type of fiber-optic cable transmits a single beam of light, allowing for greater distances and transmission speed
single-mode fiber
What are three common size-types of fiber optic cable?
- 62.5-micron core / 125-micron cladding multimode
- 50-micron core / 125-micron cladding multimode
- 8.3-micron core / 125-micron cladding single-mode
What four types of media converters are there?
a) Single-mode fiber —> ethernet
b) Multi-mode fiber —> ethernet
c) Fiber —> coaxial
d) Single-mode —> multimode
What is a BSS?
(basic service set) all the client devices that connect to a WLAN using a particular AP
a BSS is identified by its BSSID
What is an ESS?
the full group of participants in a large WLAN that includes multiple AP’s with the same SSID. it includes clients that connect to the same WLAN using different AP’s.
What is a SSID?
a unique name used to identify one WLAN from another in the same area.
