Data Rate: 1Gbps
reduced crosstalk compared to cat 5
Cat 6e
Network: 10G Base-T
Data Rate: 10Gbps
augmented, supports twice as many frequencies as cat 6
MMF: Multimode Fiber
- shorter distance limitations
* multimode delay distortion:
SMF: Single Mode Fiber
- only one mode of propagation, core diameter is smaller to only permit one mode of propagation
- longer distance limitations
- higher cost
RJ45 Connector
- twisted pair connector
* 8pin connector
RJ11 Connector
Twister Pair Connector
- up to 6 pin connector, most have only 2 or 4
- found in most home telephone networks
DB9 (RS232) Connector
Twisted Pair Connector
- 9 pin
- older connector used for low speed asynchronus serial communications - PC to a serial printer, PC to a console port of a router/switch, PC to external modem
Straight Tip (ST)
Fiber Optic Connector
- “bayonette connector”
- used in MMF
- Connects a terminating device by pushing the connector into the terminating equipment and then twisting the connector housing to lock into place
Subscriber Connector (SC)
Fiber Optic Connector
- “standard/square” connector
- Connected by pushing the connector into the terminating device, can be removed by pulling the connector from the terminating device
Lucent Connector (LC)
Fiber Optic Connector
* Connects to a terminating device by pushing the connector into the terminating device, can be removed by pressing the tab on the outer connector and pulling it out
Mechanical Transfer Registered Jack (MTRJ)
Fiber Optic Connector
- two fiber stands included in a single connector (transmit and receive)
- Connected by pushing the connector into the terminating device, can be removed by pulling the connector from the terminating device
