All frame relay networks are packet-switched networks.

All frame relay networks are packet-switched networks.

CAT3

 

·         Unshielded twisted pair capable of speeds up to 10Mbit/s. Used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet.

 

CAT4

 

·         Unshielded twisted pair capable of speeds up to 20Mbit/s. Not widely used. Used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet.

 

CAT5

 

·         Unshielded twisted pair capable of speeds up to 100Mbit/s. May be used with 10Base-T, 100Base-T4, 100Base-T2, and 100Base-TX Ethernet.

 

CAT5e

 

·         Enhanced Cat 5 is similar to CAT5, but exceeds its performance. Improved distance over previous categories from 100m to 350m. May be used for 10Base-T, 100Base-T4, 100Base-T2, 100BaseTX and 1000Base-T Ethernet.

 

CAT6

 

·         Can transmit data up to 220m at gigabit speeds. It has improved specifications for NEXT (Near End Cross Talk), PSELFEXT (Power Sum Equal Level Far End Cross Talk), and Attenuation. Cat 6 is backward compatible with lower Category grades and supports the same Ethernet standards as Cat 5e.

 

Multimode Fiber

 

·         Multimode fibers have large cores. They are able to carry more data than single mode fibers though they are best for shorter distances because of their higher attenuation levels.

 

Single Mode Fiber

 

·         Single Mode fibers have a small glass core. Single Mode fibers are used for high speed data transmission over long distances. They are less susceptible to attenuation than multimode fibers.

 

RG59 and RG6

 

·         These are both shielded coaxial cables used for broadband networking, cable television, and other uses.

 

Serial

 

·         A serial cable is a cable that can be used to transfer information between two devices using serial communication, often using the RS-232 standard. Typically use D-subminiature connectors with 9 or 25 pins. Cables are often unshielded, although shielding cables may reduce electrical noise radiated by the cable.

 

STP

 

·         differs from UTP in that it has a foil jacket that helps prevent cross talk. Cross talk is signal overflow from an adjacent wire.

 

Plenum grade cabling

 

·         is required if the cabling will be run between the ceiling and the next floor (this is called the plenum).

 

Simplex

 

·         Signals can be passed in one direction only.

 

ST

 

·         is a fiber optic connector which uses a plug and socket which is locked in place with a half-twist bayonet lock. The ST connector was the first standard for fiber optic cabling. ST Connectors are half-duplex.

.

SC

 

·         is a fiber optic connector with a push-pull latching mechanism which provides quick insertion and removal while also ensuring a positive connection. SC Connectors are half-duplex.

 

LC

 

·         just like a SC connector only it is half the size. Like SC connectors, LC connectors are half-duplex.

 

10Base-T

 

·         Category 3 or better UTP cable, 10 mbps

 

100Base-TX

 

·         Cat 5 twisted pair, 100 mbps

 

100Base-FX

 

·         Fiber Optic, ST, SC, 100 mbps

 

1000Base-T

 

·         CAT5e or higher, 1 gbps

 

1000Base-LX

 

·         Laser over fiber, SC, 1 gbps

 

1000Base-SX

 

·         laser over fiber, SC, 1 gbps

 

1000Base-CX

 

·         Twinax or short haul copper,1 gbps

 

single-mdoe, and, multi-mode, LC, SC, 10 Gbps

 

·         10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 10GBASE-SW, 10GBASE-LW, 10GBASE-EW

 

10GBASE-T

 

·         Cat 5e (or higher), 10 Gbps

·         155 mbs

 

OC-12

 

·         622 Mbs

 

OC-48

 

·         2.5 GB
