Given A Scenario, Deploy The Appropriate Cabling Solution
- contains four pairs of wires surrounded by a plastic
jacket that can transmit and receive data. - Unprotected by EMI
UTP(Unshielded twisted Pair
- consists of twisted pairs of wires surrounded by shielding to protect them from EMI
- six types
- cost more
STP(Shielded Twisted Pair)
- central conductor wire (usually copper) surrounded
by an insulating material, which, in turn, is surrounded by a braided metal shield. The cable is referred to as coaxial (coax for short) because the center
wire and the braided metal shield share a common axis or centerline
Coaxial
Type of 8 Wire connector
RJ-45
Telephones used RJ-11 connectors, designed to support up to two pairs of UTP wires
RJ-11
Back in the day, the most popular cable used special bayonet-style connectors (RG58)
BNC
The most common serial port at the end of the technology was a 9-pin, male D-subminiature
DB-9
Parallel was also limited to point-to-point topology, meaning directly connecting two devices with a single cable. They used a 25-pin female
DB-25
- used to connect televisions to cable boxes or to satellite receivers
- screws on
F-type
- connectors are always duplex, meaning both the send and receive cables are attached.
LC connector
Fiber-optic connector used primarily with 2.5-mm, singlemode fiber. It uses a push on, then twist-to-lock mechanical connection commonly called stick-and-twist although ST actually stands for straight
tip.
ST connector
Fiber-optic connector used to terminate single-mode and multimode fiber. It is characterized by its push-pull, snap mechanical coupling, known as “stick and click.” Commonly referred to as subscriber connector, standard connector, and sometimes, square connector.
SC connector
Three subtypes
- APC 8-degree angle to the curved end, lowering signal loss further
- UPC polished extensively for a superior finish. These reduce signal loss significantly over PC connectors
- MTRJ The first type of small form factor (SFF) fiber connector, still in common use
Cisco module that enables you to add additional features to its routers
small form-factor pluggable (SFP)
Modular port that supports a standardized, wide variety of gigabit interface modules.
GBIC
enhanced small form-factor pluggable used in 10 GbE networks
(SFP+),
BiDi fiber-optic
connector used in 40GBase networks.
