Support

The Client is a Fiber Optical company. It
produces Passive and Active Fiber Optics
Components Coarse Wave Length Division
Multiplexer (CWDM) and Gigabit Interface
Controller (GBIC) respectively.


Business Challenges


The client launched an organization wide
initiative to achieve higher productiv
ity in
manufacturing and telcordia compliance of
above components. This project involved
analyzing the client’s need to achieve the
desired initiative. The current process and
technology adopted by client were inefficient
and were not scalable to the desir
ed limits.


Technical Challenges


There was a need to build a sophisticated Fiber
Optics Alignment Workstation for laboratory and
for industrial production. Imaging, motion and
data acquisition needed to be fully integrated.

Coarse alignment needed to be c
ontrolled by
imaging and allowing accelerated cycle times
and setup flexibility. A special Optical Power
Tracking algorithm needed to be adopted to
provide a very fast multi
-
axis alignment.



There was a need to build various other
systems and applications

to automate or semi
automate various steps of component
manufacturing and telcordia compliance for
both passive and active components.


Gap Analysis


Various technologies and platforms were
reviewed to identify the suitable tools to build
the desired syst
ems and applications. The
hardware configuration was rigorously
analyzed.


Process Utilized

The process utilized application developed
using Lab View, Lab Windows, VC++, VB,
Measurement Studio, TestStand, Sql Server,
Visual Studio.Net, NI 4882 libraries.
It utilized
communication channels such as GPIB, RS
-
232, TCP/IP, SMTP, I2C, VISA, PXI, SCXI, VXI
and remote GPIB over the LAN (NI). The
process also utilized the hardware equipments
such as PolyTek PI (6 axes alignment system),
Power Meters, Lasers, Polari
zation Controllers,
Temperature Chambers, BERT, Signal
Analyzers, OSA’s, Attenuators, Amplifiers,
Optical Switches, GPIB cards, Thermo
Couplers, Leak Detection Systems, Smart
Scopes, Camera’s etc etc..

Product Test Solutions
:

The Test Solutions used popular off
-
the
-
shelf software tools, such as, National
Instruments Test Stand to quick
ly provide
the test software, minimizing valuable
engineering resources. Data was captured in
standardized file formats, which can be
accessed using Microsoft Excel as well as
data was logged to an ODBC compliant
database (Sql Server 2000). Data was
stored

on the test system computer, as well
as, on a separate database server.


The generic interface was designed with a
product specific Interface Test Adapter
(ITA). The ITA allows the generic interface to
be quickly modified to create various test
automation

application with different
products.


The generic interface uses a combination of
COTS instrumentation employing a GPIB
bus. This platform provides an open
architecture for future upgrades and/or
expansion, yet offers a lower cost solution
than other tech
niques.




Conclusion


Confidence that systems that is utilized for
passive components, desired by client was
built. Raised awareness of Automation as
opposed to manual systems. Telcordia
compliance was achieved. The active
product automation was achieve
d.
