Q

STP Shielded twisted pair & Direct Burial STP

A

Additional shielding protects against interference– Shield each pair and/or the overall cable– Requires the cable to be ground.

Overhead cable isn’t always a good option– Put the cable in the ground
* Provides protection from the elements– Designed to be waterproof– Often filled with gel to repel water– Conduit may not be needed.
* Shielded twisted pair– Provides grounding, adds strength– Protects against signal interference.

Q

T568A and T568B termination

A

Pin assignments from T568-B standard– Eight conductor 100-ohm balanced twisted-pair cabling. T568A and T568B are different pin assignments for 8P8C connectors– Assigns the T568A pin-out to horizontal cabling. Many organizations traditionally use 568B. Difficult to change mid stream. You can’t terminate one side of the cable with 568A and the other with 568B– This has never been the definition of a
Gigabit Ethernet crossover cable.

17
Q

Digital Visual Interface (DVI)

A

Single and dual link. Single link; 3.7 Gbps (HDTV at 60 fps). Dual link; 7.4 Gbps (HDTV at 85 fps). No audio support.

18
Q

Video Graphics Array (VGA)

A

DB-15 connector– More accurately called DE-15. Blue color– PC System Design Guide. Analog signal– No digital– Image degrades after 5 to 10 meters.

19
Q

Serial Advanced Technology
Attachment (SATA)

A

One power cable and data cable per device. One to one.

20
Q

Small Computer System
Interface (SCSI)

A

Small computer systems interface. Originally designed to string many peripherals together onto a single cable/controller, Many different formats– Fast SCSI, Ultra SCSI, Ultra Wide SCSI, Ultra2 SCSI, – Ultra3 SCSI, Ultra-320 SCSI, Ultra-640 SCSI, – iSCSI (SCSI over IP). Parallel and serial options.

21
Q

External SATA (eSATA)

A

External device connections. Uses the SATA standard. Similar in size to SAT. Connectors are physically different.

22
Q

Integrated Drive Electronics
(IDE)

A

The PATA standard. A Western Digital invention. 2nd generation called EIDE (Enhanced IDE). The evolution– Promised faster speeds– From 16 MB/s through 133 MB/s– Additional devices.

23
Q

RJ11

A

6 position, 2 conductor (6P2C)– Some cables will wire additional conductors– Telephone or DSL connection.
