Cable length: Some basic requirements are twisted-pair
cable should not be more than 100 meters from a switch.
Also to prevent fire spreading from Ethernet cables
installed between ceiling and floor and prevent spreading
of spread toxic gases Special plenum type cables should
Device types/requirements: Some devices required
for SOHO networks are desktops, laptops, routers, switches,
printers, faxes machines.
Environment limitations: Routers and switches should
be saved from flooding or high humidity and optimum
operating temperature should be maintained. In wireless
networks absorption or refection of radio waves should
Equipment limitations: SOHO net works are generally
a scaled-down version of the same type of device you
would use for an enterprise network, should use SOHO
equipment for SOHO environment, but you should generally
not use it for a larger enterprise environment
Compatibility requirements: A compatible media, client
or service, and protocol must be used.
Multimode fiber: It carry multiple rays of light
concurrently and different reflection angle. These can
carry short distances as strength weakens over distance.
Single mode fiber: It can carry single direct ray
of light. It can travell longer distance as distortion
is less as compared to multimode fiber.
UTP stands for Un-shielded Twisted Pair cabling.
A cable made up of 8 individual wires. 4 pairs twisted
together. f wires in a cable are not twisted or shielded,
that cable can act as an antenna, which might receive
or transmit EMI. To help prevent this type of behavior,
the wires (which are individually insulated) can be
twisted together in pairs.
STP for Shielded Twisted Pair cabling. environments
in which greater resistance to EMI and attenuation is
required. provides the extra shielding by using an insulating
material that is wrapped around the wires within the
cable. This extra protection increases the distances
that data signals can travel over STP but also increases
the cost of the cabling.
CAT3: This standard was used in 90's for homes and
offices. It can transmit data up to 10Mbps with a possible
bandwidth of 16MHz
CAT5: It uses either the 10BASE-T or 100BASE-T standard
for data transmission Using two cable pairs to signal
over copper wire. It provides a minimum of 100MHz of
CAT5e: It uses four pairs of copper wire. In addition,
the wire pairs are twisted more tightly and are sheathed
in heavy-duty shielding to eliminate crosstalk. It is
used for 1000BASE-T networks, which carry data at a
rate of 1 Gbps.
CAT6: It can transmit data up to 10Gbps, has a minimum
of 250MHz of bandwidth and specifies cable lengths up
to 100 meters with 10/100/1000Mbps transfer, along with
10Gbps over shorter distances. It is made up of four
twisted pairs of copper wire, an longitudinal separator
separates each of the four pairs of wires from each
CAT 6a: It can operate at a frequency of up to 750
MHz and is even less susceptible to interference and
crosstalk CAT6a is the preferred cable for 10GBASE-T
Straight-through: The Cable is wired the same on
both sides following the 568a or 568b wiring schematic.
Plenum cable: It is fire retardant and minimize toxic
fumes released if a networking cable catches fire.
