2. Unit –III​ Identification of​ Connectors​

3. Identify various types of cables …
❖Twisted pair cables (UTP/STP)
❖Fiber cable
❖Coaxial cables
❖Ribbon cables

4. Connector
❖A connector is a device that joins two
pieces of equipment, wire, or piping
together.​

5. Why used connectors ?
❖Connectors are used to join subsections of circuits together.
Usually, a connector is used where it may be desirable to
disconnect the subsections at some future time: power inputs,
peripheral connections, or boards which may need to be replaced.​

6. Twisted pair cables (UTP/STP)
❏Both UTP and STP are widely used in transmitting
information across distance. UTP is a cable with wires that
are twisted together to reduce noise generated by an
external source. On the other hand, STP is a twisted pair
cable with an additional mesh shield that guards the cable
against electromagnetic interference.
❏STP (Shielded Twisted Pair) cables have an extra layer of
shielding compared to UTP (Unshielded Twisted Pair) cables.
This shielding protects against electromagnetic interference
but makes STP cables more expensive, heavier, and harder to
install.

7. Fiber cable
➔A fiber-optic cable, also known as an optical-fiber cable, is
an assembly similar to an electrical cable but containing
one or more optical fibers that are used to carry light. The
optical fiber elements are typically individually coated
with plastic layers and contained in a protective tube
suitable for the environment where the cable is used.
Different types of cable are used for optical
communication in different applications, for example
long-distance telecommunication or providing a high-
speed data connection between different parts of a
building.

8. Types of Fiber cable cables
●OFC: Optical fiber
●OFN: Optical fiber
●OFCG: Optical fiber
●OFNG: Optical fiber
●OFCP: Optical fiber
●OFNP: Optical fiber
●OFCR: Optical fiber
●OFNR: Optical fiber
●OPAC: Optical attached cable
●OPGW: Optical fiber composite overhead ground wire
●ADSS: All-dielectric self-supporting
●OSP: Fiber optic cable, outside plant
●MDU: Fiber optics cable, multiple dwelling unit

9. Coaxial Cable
★Coaxial cables have concentric layers of electrical conductors and
insulating material. This construction ensures signals are enclosed within
the cable and prevents electrical noise from interfering with the signal.
The center conductor layer is a thin conducting wire, either solid or
braided copper.
★A dielectric layer made of an insulating material with well-defined
electrical characteristics surrounds the wire. A shield layer then
surrounds the dielectric layer with metal foil or braided copper mesh.
The whole assembly is wrapped in an insulating jacket. The outer metal
shield layer of the coaxial cable is typically grounded in the connectors at
both ends to shield the signals and as a place for stray interference
signals to dissipate.

10. Types of Coaxial cable
❖Rigid coaxial cable
❖BNC
❖TNC
❖DIN
❖F connectors
❖SMA
❖SMB
❖FME
❖RCA
❖RG59
❖Coaxial cable rating
❖SMC connectors
❖Formable coax

11. Ribbon Cable
★Ribbon cables are usually specified by two
numbers: the spacing or pitch of the conductors,
and the number of conductors or ways. A spacing of
0.05 inch (1.27 mm) is the most usual, allowing for
a two-row connector with a pin spacing of 0.1 inch
(2.54 mm).
★These types are used for many types of equipment,
in particular for interconnections within an
enclosure. For personal computers, this size was
used in floppy-disk-drive cables and older or
custom Parallel ATA cables.
