Introduction

• Bharat Sanchar Nigam Limited was established in October 2000 and

its headquarters are in Delhi.

• It is fourth largest department of Tele Communication Company in

Asia and tenth in world today. Which is one of the most earning

revenue in India. Above more than 3 laces employees, officer and

engineers working in BSNL at present.

Introduction...

It provides comprehensive range of telecom services in India: Wire

line, CDMA mobile, GSM Mobile, Internet, Broadband.

BSNL cellular service, Cell One,

• 90.09 million cellular customers

• 5.06 million WLL customers,

• 24.58 million Basic Phone subscribers i.e. 71.93 per cent share

of the subscriber base.

EXISTING SYSTEM

The transmission system consists of

1.Switching Equipment

2. Main Distribution Frame

Construction of MDF is• Verticle side or line side

• Horizontal side or LEN side or exchange side

3.Switch Room

4.Power Plant

4.Battery Room

Practical Exposure1.Optical FiberTypes:

Color codes

SPLICING

Cutter that is used prior to splicing

Splicing types1.Mechanical Splicing

2.Fusion Splicing

3.Chemical Splicing

1.Mechanical splicing

Capillary Splicing

Elastomeric Splicing

Mechanical splicing...

Rotary Splicing

2.Fusion Splicing

Fusion splicing two fibers involves several steps. End preparation are Striping (cable jacket, buffer tube & coating), Cleaving, Cleaning the end surface.

FTTH(Fiber to the home)

• It is the form of fiber optic communication network in which optical signal reaches upto the end user’s office.

FTTH...

• Direct fiber:Here each fiber leaving the central office goes to exactly one customer .i.e. point to point topology. Provides excellent bandwidth because each customer have their own dedicated fiber.

2.SHARED FIBERIn this architecture, each fiber leaving the central

office is actually shared by many customers. There are two leading optical distribution networks with which we can achieve this split.

1.Active optical network (AONs)2.Passive optical network (PONs)

1.AON Architecture:

PON architecture:

OTDR

Based on Reyleigh scattering

OTDR principle

Software Packages of BSNL

• SSANeT • Dotsoft• GPMS (Group Performance Management Syst

em)• CLARITY• CRM(Customer Relationship Management )• PGMS(Performance Grievance Management

System) and many..

Software's used IN BSNL FOR MAINTANANCE

• CRM(Customer Relationship Management )• PGMS(Performance Grievance Management

System)• DOTSOFT

• Clarity and many..

Purpose of Clarity

• Manage Network and Number Inventory

• Automate service procedures, inventory management and reduce turnaround time for service requests

• Allocate appropriate work force based on the

activity to be performed for various tasks during service provisioning/ deprovisioning.

SCRIBBLE MAP AND LAT LONG MEASUREMENTSAHAKAR NAGAR EXCHANGE

Scribble maps...

•This is a feature that has got requests for and that is the

ability to create a map widget where regions can link ou

t to different websites/pages. So we are excited to anno

unce you can now do this in Scribble Maps!Creating a

clickable map is as simple as clicking the pencil (edit) i

n the layer panel for the overlay.

Lat-Long Measurement:

•For finding the position of the optical fiber laid.

Lat-Long measured

IMPACT OF INTERNSHIP

• COMPANY EXPOSURE

• REAL TIME WORK EXPOSURE

• EXPOSURE TO SPLICING TECHNOLOGY AND CLARITY SOFTWARE.

• TEAM WORK.
