Bidirectional Converter
Connects networks using both SMF and MMF
Also connects copper to fiber based parts of a network
RJ-11
Telephone jack
Connects phone line to modem
4 wires
Used for dialup
RJ-45
Ethernet Jack
Used to connect LANS
8 wires
BNC
Bayonet Neil Concelman (British Naval connector)
Male adapter uses with 10BaseT Ethernet
Used with RG-58A/U cabling scenarios
And a lock you twist cable to seat in.
DB-9 Connector
9 pin D type
Serial interfaces
Common for keyboards, mice and joysticks
1 bit per cycle
DB-25
Analog 25 pin D sub connector Parallel connections Originally used to connect printers 8bits per cycle Data always arrives at the same time
F-Type connector
Coax threaded connector
Common in TVs and Cable modems
It’s screws on and is a stable connection
LC Fiber connection
A push/pull connector
Used in data comms and high density patch panels
Has a high density and is const effective
UPC fiber connector
Ultra Physical Contact
Done shaped
optimises connections between 2 jacketed fiber cables
Reflex’s light back to the source called return loss that causes interference
APC fiber connector
End is angled at 8 degree to reduce light reflection between two connected fibers
Reflected light hits cladding to reduced interface and return loss
Is more expensive than UPC
MT-RJ fiber connector
Mechanical Transfer Jack
Used in small form factor devices
Fiber to desktop or fiber modems
Fiber transceiver
Adaptor allowing interconnection of different network devices the use different physical media for data transferring
SFP Transceiver
Small form factor pluggable
Plugs into a SFP port on a switch to provide a modular interface
Enables different networking standards
SFP+
Small form factor pluggable +
Enchanted version
Handles 10gbps
Requires addition circuitry
Found in plug in cards for servers or switches
GBIC
Gigabit Interface Converter
Converts electrical current to optical signals and back
1gbps or more transfer speed
Was replace by SFP
QSFP
Quad small form factor pluggable
Used for data communication applications
Handles four different channel configurations
Bidirectional
BiDi
Uses wavelength division multiplexing (WDM)
Simultaneous transmission on a single fiber in birth directions
Used only for fiber
Different frequencies used
BiDi SFP and SFP+
Rescued infrastructure costs
Less cabling, tray space and fewer latch panel ports needed
Duplex Tranceiver
Inter connects devices using different Dulles configurations
2 fibers, 1 sends and 1 to root
Half Duplex = send and receives both directions one at a time
Full Duplex = send and receive both at the same time
Termination points
Centralised device connection
66 Block (Punchdown block)
Commonly used as telephone systems cross connect
50 wire pairs
Wires connect to terminals using punchdown tool
Connects phones to offices by using extension numbers
110 Block
Punchdown media type used in data networks
25 to 500 wire pairs
Metal jumpers used to bridge connections
Patch panel
Ethernet connectors
Connects switches ect using Ethernet (RJ-45)
Can use a patch panel for fiber and as a fiber distribution panel where a multi fiber backs can split into multiple individual cables
Easy to re configure and improves cosmetic appearance in cabling rooms.
Cat 3
Copper cabling
UTP
telephone wire
Up to 10mbps
Cat 5
High performance multiple pair
8 wires
Twisted pair
10 to 100mbps
Cat 5e
Supports full duplex fast and Gigabit Ethernet
Used in networks
100mbps to 1 gbps
Cat 6
Higher performance Reduced cross talk and system noise Backward compatible with 5e, 5, 3 cabling devices Carey high speeds for longer distance 1 to 10gbps
Cat 6a
10gb Ethernet
Twisted pair
Bandwidth 500MHz
Requires matching components to be 6a compatible
Has shielding as default where 6 didn’t
Reduced cross talk and increased distance
Cat 7
Frequency of 1 to 600MHz
Over 100mbps reliable 10gbps distance
Used in 10gb Ethernet
RG-6
Common for TV, Satellite, TV antenna and broadband Internet large conductor core provides better signal quality
Harder to implement
RG-59
Common TV cable
Smaller than RG-6 which affects signal quality
Good for low signals under 50MHz
10BaseT
Fast Ethernet IEEE 802.3
Up to 100mbps
10= Speed Base= uses 100% or 0% of available bandwidth T= Twisted Pair
Broadband
Uses variation in frequency where you have to tune correct channel.
It’s shared bandwidth
100BaseTX
Uses 2 pairs
10BaseT4
Uses 4pairs (all 8 wires)
100BaseFX
Is Fiber
1000BaseT
Gigabit Ethernet over copper wire
IEEE 802.3 Specs
Supports 1gbps up to 100mbps before signal needs boosting
Easy to implement
Backward compatibility
You can use 10BaseT and 1000BaseT at the same time but will only get 1gbps over network sections that support 1000BaseT
1000BaseLX
Gigabit Ethernet
LX = long distance fiber cabling
Used to cable between companies or building
1000BaseSX
Short
