15. MDF
• This module is for transfer of
data
• By MUX AND DEMUX
• In this module mux(4*1) the
transfer is done converting the
data in form of light signal by
convertors to pass as a single
signal through a optical fibre
• These transfer rates(speed)
increases by increasing the
module conversion number at a
time like 32*1.

16. CODE DIVISION MULTIPLE ACCESS (CDMA)
• Code Division Multiple Access (CDMA) consistently provides better
capacity for voice and data communications than other commercial
mobile technologies, allowing more subscribers to connect at any
given time, and it is the common platform on which 3G technologies
are built.
• CDMA is a spread spectrum technology, allowing many users to
occupy the same time and frequency allocations in a given
band/spaceADVANTAGES OF CDMA:
• Increased cellular communications security
• Simultaneous conversations
• Low power requirements and little cell-to-cell
coordination needed by operators.
• Extended reach-beneficial to rural users situated far
from cells.

24. BSNL BROADBAND SERVICE
• Broadband refers to a connection that has capacity to transmit large amount of
data at high speed.
• Presently a connection having download speeds of 256 kbps or more is
classified as broadband.
• When connected to the Internet broadband connection allows surfing or
downloading much faster than a dial-up or any other narrowband connections.
• BSNL offers 2 Mbps minimum download speed for its Broadband connections.
Requirement for providing Broad Band connection
1.Personal Computer
2.ADSL Modem
3.Land Line Connection

27. FTTH (FIBER TO THE HOME)
• Fibre to the Home (FTTH)
is a unique technology
being deployed by BSNL
for the first time in India.
• The fibre connectivity
having unlimited
bandwidth and state of the
art technology provides fix
access platform to deliver
the high speed broadband
from 256 Kbps to 100
Mbps.

28. • An optical fiber cable is made of glass (Quartz) and transmits
the signal in the form of light.
OPTICAL FIBER CABLE

29. • In fusion splicing a machine is
used to precisely align the two
fiber ends then the glass ends
are "fused" or "welded"
together using some type of
heat or electric arc.
• This produces a continuous
connection between the fibers
enabling very low loss light
transmission.
