TOPIC:
Objectives: At the end of the discussion, the participants must have:
a. Define OSP and its significance in telecommunications,
b. Draw the tools and materials needed in subscriber line installation; and
c. Apply safety precautions and guidelines related to OSP installation.
I. TELECOM OSP AND SUBSCRIBER LINE INSTALLATION
What is OSP?
Outside plant in telecommunications refers to all of the physical cablings
and supporting infrastructure (such as conduit, cabinets, towers, or
poles), as well as any associated hardware, placed between a
demarcation point in one switching facility and another switching center
or customer premises.
The communications equipment positioned between the main distribution
frame (MDF) and a user end equipment might be considered outside
plant. The inside plant is the section of this infrastructure contained
within a building, while the outside plant is the portion of this
infrastructure connecting buildings or institutions. The demarcation point
in a given structure is where these two plants meet.
Outside plant cabling, including copper or fiber, is typically installed as
aerial cable between poles, in an underground conduit system, or
through direct burial. Outside plant hardware must be either protected
from the elements or built with materials that can withstand exposure to
the elements. Outside plant installation commonly requires the
construction of considerable physical infrastructure, such as underground
vaults.
Outside plant cabling must also be safeguarded from electrical
disturbances such as lightning strikes or voltage surges caused by
electrical shorts or induction.
Subscriber installation, in the context of telecommunications, refers to
the process of connecting and setting up services for individual
subscribers or end-users at their premises. This installation involves
deploying the necessary equipment, cabling, and devices to establish
communication services such as internet, telephone, and television at a
residential or business location.
II. TOOLS, MATERIALS, HARDWARE, AND OTHER ACCESSORIES
Tools:
1. Fiber Optic Cable Tools:
Fusion Splicer
Cleaver
Fiber Stripper
Fiber Optic Connector Cleaner
Visual Fault Locator (VFL)
Optical Power Meter (OPM) and Light Source
Cable tester
Lineman’s handset
DSL tester
Screwdrivers
Materials:
Copper Cables (POTS- Plain Old Telephone Service)
is a group of two or more copper wires bundled together in a single
sheath or jacket. Copper wire and cable is used in power generation,
power transmission, power distribution, telecommunications,
electronics circuitry, and countless types of electrical equipment.
DSL- enable copper cables
DSL uses existing copper phone lines to transmit internet and TV
signals. A copper phone line is like a highway with four lanes.
Distribution Terminals
Insulation displacement connectors (IDCs)
An insulation-displacement contact or connectors (IDC), also known
as insulation-piercing contact (IPC), is an electrical
connector designed to be connected to the conductor(s) of an
insulated cable by a connection process which forces a selectively
sharpened blade or blades through the insulation, bypassing the need
to strip the conductors of insulation before connecting. When properly
made, the connector blade cold-welds to the conductor, making a
theoretically reliable gas-tight connection.
Cable Ties
Cable markers
Hardware:
Distribution Terminal (DP)
DSL modems
Mounting Brackets
Grounding equipment
Splice closures
Other Accessories:
Protective Gloves
Safety Goggles
Ladder
Labeling Materials
blank film, paper or other backing
In conclusion, Telecom Outside Plant (OSP) and subscriber installation
are critical components of telecommunications infrastructure deployment,
ensuring connectivity and services for end-users. OSP installation involves
the physical deployment of network elements outside of buildings,
encompassing fiber and copper cabling, conduits, distribution frames,
grounding, and other hardware. This infrastructure is essential for
establishing the backbone of telecommunications networks.
On the other hand, subscriber installation focuses on bringing
telecommunications services directly to individual end-users at their
residences or businesses. This process includes cabling, equipment
installation (such as modems and routers), network connection, testing,
and activation. Subscriber installation is vital for enabling users to access
services like internet, telephone, and television.
