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.
quad small form-factor pluggable (QSFP)
have only a single optical port designed inside to send on one wavelength, such as 1310 nm, and receive on a different wavelength, such as 1550 nm. A corresponding BiDi transceiver must be installed on the other end of the fiber for this to work.
BiDi transceiver
- punchdown blocks common in telecommunication
- one or more 25-pair UTP cables
66 block
- Introduces less crosstalk than 66 blocks, so most high-speed network installations use the former for both telephone service and LANs
- used to link UTP and STP cables behind an RJ-45 patch panel
110 block
- a box with a row of female ports in the front and
permanent connections in the back, to which you connect the horizontal cables - come with Cat ratings
Patch panel
- 10BaseT
- can operate at up to 16 Mbps
Cat 3
- Standard for UTP wiring that can operate at up to 100 Mbps/100m
- 100mhz
Cat 5
- 100-1000mb/s at 100 meters
Cat 5e
- 1gb/s at 100 meters or 10gb/s at 10 meters
- 250mhz
Cat 6
