"After I get rested up, Wavelength and I are going
to have some of these non-believers for dinner."
"Now you probably want to know what
Dog Wash really is - don't you?  Let me
explain it to you one step at a time."
• Fiber is too fragile to survive harsh conditions - Dog Wash
• Fiber’s performance capabilities are unnecessary - Dog Wash
• Fiber is more difficult to install than copper - Dog Wash
• Switching from copper to fiber is expensive – and not worth the trouble - Dog Wash
• A forklift upgrade to fiber is too costly to implement - Dog Wash
• Long-term copper users claim they don’t need fiber - Dog Wash
• Fiber is too fragile to survive harsh conditions
temperature and pressure extremes. In fact, tensile strength (resistance to pulling) of optical fiber exceeds 600,000 pounds per square inch – making it
stronger than copper or steel strands of the same diameter and easily surpassing the strength requirements of today’s communications applications. When
cabled, glass fiber is protected and further strengthened by aramid or fiberglass yarns, a fiberglass rod, and/or an outer jacket constructed of non-
conductive materials. Fiber has also demonstrated a long service life, possessing high information carrying capacity, resistance to electromagnetic
interference (EMI) and immunity to corrosion. Plus, its small size and light weight make it easier to handle in narrow duct spaces.

"Makes a smart fiber optics technician/network designer want to think
twice about all that Plenum Innerduct.  An installer once told me the only
reason he installed his one little piece of 6-fiber cable in that big ole
expensive plenum innerduct was so that it could be recognized as fiber.  
Real smart - considering that Plenum Innerduct is so expensive.  By the
way - if you know how to read an OTDR you will see that the fiber is still
not broken!"

Reliability: Fiber has proven that it can transmit information error-free over greater distances than copper and support higher data rates at the same
time. If your company’s LAN is experiencing bottlenecks, high error rates, slow throughput or downtime, an optical fiber solution supports a broader
range of bandwidth capabilities, thus improving your network performance and decreasing downtime.

Security: Optical fiber is the most secure transmission medium, because it is immune to EMI and Radio Frequency Interference (RFI). Since fiber
transmits light rather than electricity, it is not affected by the EMI from power, radio or microwave sources.  Furthermore, fiber is immune to crosstalk and
is extremely difficult to tap – qualities that cannot be claimed by copper. While information security has led to wide use of fiber by financial institutions
and the military, it is also extremely important to the average small business and factory owner. Signal interference can pose a huge problem to factory
applications and other areas with a variety of electronics if copper is their only current solution.

"Did you know that the maximum pulling
tension for indoor fiber is 200 lbs.  Maximum
pulling tension for UTP copper is 25 lbs?  
Gee - I even knew that!"
