CASE STUDY : Providing connectivity in a manufacturing unit

Aambernet, along with Orva Net­works, a Bangalore-based SI, deployed a fiber
optic/copper solution for connec­ting the campus of a manufacturing unit in
Bangalore.

The manufac­turing unit project was cons­tructed in three phases. The builder
wanted to inter­connect all the buil­dings in 3 phases using an optic fiber as
backbone on a mesh topology.

Orva Networks pro­vided the basic system integration like laying,
termi­nating and testing the cabling solution. Apsis Technologies trained Ovra
on the nuances of providing structured cabling solutions. Apsis prepared the
design and planning through its team and allocated the integra­tion work to Ovra
Networks.

Building architecture

The entire project was split into three phases. Phase 1 consisted of
connecting two buildings-the engineering and factory building, and the admin
building, which surrounded the customer care and central amenities buildings.

The aim of the project was to interconnect these three buil­dings without
disturbing the manufacturing unit.

Backbone Room

Apsis Technologies suggested the builder to provide a separate room called as
the Backbone Room at the ground floor level of the admin block. This block was
located 3.15mt from ground level, away from the cables of different service
providers (SP) like BSNL, Airtel, Tata Indicom, VSNL, Reliance used for
telephone land lines and leased circuits. This point is identified as Point of
Demarcation in the customer premises, thus the outside plant cables are housed
and managed at a single point.

Single mode fiber cable was used for backbone between the proposed blocks

The Backbone Room also had the Copper Incoming Circuit Design and Fiber
Incoming Circuit Design incoming copper and fiber links for both data and voice
from different service providers and DLC Provision.

Apart from the communi­cation room, a dedicated space was allocated as
Network Room where all the building backbone cables were housed and managed.
Aambernet decided to set up Voice Backbone, Data Backbone and a termination
architecture in the Networking Room.

Voice Backbone: Each block (Eng I & II, ADMN, Factory Block, Customer Care
and Central Amenities) were inter­connected through a 12 core composite fiber
cable; also Armored Copper of cable were deployed in 400 and 100 pair
configurations for voice

Data Backbone: Each block (Eng I & II, ADMN, factory, Customer Care and
Central Amenities) was interconnected through a 12 core Single Mode fiber cable;
A single mode fiber cable in 10G configuration was suggested since the distance
between the block was exceeding more than 300mtr where a MM solution was not
appropriate.

Termination architecture: As indicated above, a 12 core composite served as
the voice backbone whilst single mode served as data backbone. The later was
terminated based on a mesh topology and the earlier was done on end-to-end
straight connectivity.

Cable used

Single mode fiber cable was used for backbone between the proposed blocks.
These cables were buried at a depth of 1.65mt in a 0.3mt wide trunk made of
high-density polye­thylene (HDPE) pipe. These pipes were packed by a layer of
river sand both top and bottom on top of which a half cut concrete with brick
pack served as conceal point. Every 50mt had connecting chambers and also route
markers were deployed

Aambernet and Orva follo­wed the ANSI/TIA/EIA 568-B.1 practices while
deploying the solution.

Cost and time

The total value of the project was approximately Rs 50 lakh and the project
was rolled out in four months. Dinakaran, Country Manager, Aambernet Range of
Networking Products, Apsis Technologies said that the implementation was done in
a systematic way to ensure that at there was minimum interruption to the regular
factory schedule.
