Stan Kubota Achieves Certified Fiber Characterization Engineering (CFCE) Status
Under the auspicies of JDSU
(www.jdsu.com/products/communications-test-
measurement/training/certifications.html ) and Optical
Technology Training (OTT, Skipton, UK) (www.fibercharacterization.com
), Stan Kubota participated in and received certification status for
fiber characterization. From the OTT course manual, “Comprehensive
fiber characterization is a complex subject that requires detailed
knowledge of many aspects of fiber optics and considerable skill and
judgement in defining test programmes, carrying out the tests,
validating the data, analyzing and interpreting the results to
provide comprehensive authoritative documentation that is often used
as a basis for making very expensive decisions.” The course was
lead by OTT’s Richard Ednay, the UK’s Principal Expert on fiber
testing participating in all major world-wide standards bodies such
as the IEC, ITU-T, ISO/IEC, TIA/EIA, etc. Mr. Ednay is also credited
with the writing of several key standards for these bodies.
Regarding the CFCE course JDSU states
“Understanding the fiber optic tests that are required to prove
that advanced fiber infrastructures can support high data rate
applications (10Gb/s, 40Gb/s) as well as extended wavelength range
operations for DWDM and CWDM systems” is an objective of this
certification. Further, students will “Apply the full power of
modern multi-purpose test platforms to carry out these tests
including bi-directional OTDR testing, chromatic dispersion,
polarization mode dispersion (PMD) and spectral attenuation.” The
course also included bi-directional insertion loss and optical return
loss testing.
Exsell is now in a unique position to
offer fiber characterization services and consulting for any fiber
optic infrastructure, new or old, that needs to verify the ability to
carry higher speed data transmission whether it be advanced Ethernet
or traditional telephony transmission such as SONET or OC-xxx
technologies (OC- 48, 192, 768, etc.). The interesting and
problematic issue is for older installed fiber optic cable that is
now required to be stitched together to reach more locations and to
carry higher data rates. What type of fiber is in my network? Will
these older fibers allow for the higher data rates? Can these fibers
or dark fibers work in conjunction with the newer fiber types that
have been developed and installed post 2000? What rates will be
achievable in these “hybrid” fiber networks? These questions and
more can be answered.
