3. THUNDERBOLT
Thunderbolt Technology is a
transformational high speed, dual core
I/O protocol which provides excellent
performance over current I/O
technologies which are available in the
market with 10Gbps bi-directional
transfer speed.
It provides flexibility and simplicity by
supporting both data and video on a
single cable connection that can daisy-
chain up to six devices
With this Thunderbolt
technology it is now
possible to enable the
thinnest and lightest laptops
can connected over a single
cable to high performance
storage, external media
drives, multiple HD
displays, HD media.

4. KEY FEATURES

7. ADVANTAGES OF CHOOSING FIBER OVER
COPPER CABLE
1. Greater bandwidth:- Fiber provides more bandwidth than
copper. More bandwidth means fiber can carry more
information with greater fidelity than copper wire.
2. Speed and distance:- Because the fiber optic signal is made
of light, very little signal loss occurs during transmission,
and data can move at higher speeds and greater distances.
3. Security:- It doesn’t radiate signals and is extremely
difficult to tap. If the cable is tapped, it’s very easy to
monitor because the cable leaks light, causing the entire
system to fail.
4. Cost:- The cost for fiber cable, components, and hardware
has steadily decreased. Overall, fiber cable is more
expensive than copper cable in the short run, but it may be
less expensive in the long run.

8. PROTOCOL IN THUNDERBOLT
8
Each Thunderbolt port on a computer is capable of
providing the full bandwidth of the link in both the
direction.
A Thunderbolt connector is capable of providing two full
duplex channels.The main focus of Thunderbolt
comes on two layers, Physical
layer and Transport layer.

9. PROTOCOL ARCHITECTURE
Physical layer is responsible for link maintenance
including hot-plug detection, and data encoding to
provide highly efficient data transfer
The heart of the Thunderbolt protocol architecture is the
Transport layer.

10. CONTROLLER ARCHITECTURE
• A high-performance, cross-bar Thunderbolt protocol switch
• One or more Thunderbolt ports
• One or more DisplayPort protocol adapter ports
• A PCI Express switch with one or more PCI Express protocol
adapter port
A Thunderbolt controller contains:
DisplayPort and PCI Express protocols are
mapped onto the transport layer.

11. CONTROLLER ARCHITECTURE CONTINUE

12. THUNDERBOLT TECHNOLOGIES AND
POSIBILITES
• No project is too massive.
If you’re a video editor, imagine using a single port to connect
high-performance storage, a high-resolution display, and high-
bit-rate video capture devices to handle all the post-production
for a feature film.
• Changing the PC industry.
Thunderbolt technology also enables the introduction of
thinner and lighter laptops without sacrificing I/O performance,
and extends to reach other I/O technologies by using PCIe-
based adapters
• Performance and expansion made faster and smarter.
Thunderbolt I/O technology gives you two channels on the
same connector with 10 Gbps of throughput in both directions.
That makes Thunderbolt ultrafast and ultra flexible.

13. THUNDERBOLT VS EXISTING I/O INTERFACE

14. THUNDERBOLT 2
In June 2013, Intel announced that the next generation of
Thunderbolt. Thunderbolt 2 is an update to the original
thunderbolt, based on the codenamed "Falcon Ridge" is officially
named "Thunderbolt 2”.
 Intel claims Thunderbolt 2 will be able to
transfer a 4K video while simultaneously
displaying it on a discrete monitor.
 At the physical level, the bandwidth of
Thunderbolt 1 and Thunderbolt 2 are identical,
and Thunderbolt 1 cabling is thus compatible
with Thunderbolt 2 interfaces. At the logical
level, Thunderbolt 2 enables channel
aggregation, whereby the two previously
separate 10 Gbit/s channels can be combined
into a single logical 20 Gbit/s channel.

15. THUNDERBOLT 3
Thunderbolt 3 is computer port delivering two 4K displays, fast
data, and quick notebook charging, said, vice president of Intel
Corporation.
Technology Features
• 40 Gbps Thunderbolt 3 – double the speed of Thunderbolt 2
• Bi-directional, dual-protocol (PCI Express and Display Port)
• 4 lanes of PCI Express Gen 3
• 8 lanes of Display Port 1.2 (HBR2 and MST)
• Supports two 4K displays (4096 x 2160 30bpp @ 60 Hz)
• USB 3.1 (10 Gbps) – compatible with existing USB devices and
cables
• Daisy chaining (up to six devices)

16. CONCLUSION
Thunderbolt technology brings a new balance of
performance, simplicity and flexibility to end users
and product designers alike
Due to cost factor, it is out of reach for an average
product for now, USB still more popular which
practically free
At present it is running at electrical standard but it
will be at optical standard in long run
