The best way I can explain this is the Wikipedia explanation
In practical fibers, the cladding is usually coated with a tough resin
buffer layer, which may be further surrounded by a jacket layer, usually
plastic. These layers add strength to the fiber but do not contribute to its
optical wave guide properties. Rigid fiber assemblies sometimes put
light-absorbing ("dark") glass between the fibers, to prevent light that
leaks out of one fiber from entering another. This reduces cross-talk
between the fibers, or reduces flare in fiber bundle imaging applications
For indoor applications, the jacketed fiber is generally enclosed, with a
bundle of flexible fibrous polymer strength members like Aramid (e.g. Twaron
or Kevlar), in a lightweight plastic cover to form a simple cable. Each end
of the cable may be terminated with a specialized optical fiber connector to
allow it to be easily connected and disconnected from transmitting and
receiving equipment.
An optical fiber breakout cable
For use in more strenuous environments, a much more robust cable
construction is required. In loose-tube construction the fiber is laid
helically into semi-rigid tubes, allowing the cable to stretch without
stretching the fiber itself. This protects the fiber from tension during
laying and due to temperature changes. Loose-tube fiber may be "dry block"
or gel-filled. Dry block offers less protection to the fibers than
gel-filled, but costs considerably less. Instead of a loose tube, the fiber
may be embedded in a heavy polymer jacket, commonly called "tight buffer"
construction. Tight buffer cables are offered for a variety of applications,
but the two most common are "Breakout" and "Distribution". Breakout cables
normally contain a rip cord, two non-conductive dielectric strengthening
members (normally a glass rod epoxy), an aramid yarn, and 3 mm buffer tubing
with an additional layer of Kevlar surrounding each fiber. Distribution
cables have an overall Kevlar wrapping, a ripcord, and a 900 micrometer
buffer coating surrounding each fiber. These fiber units are commonly
bundled with additional steel strength members, again with a helical twist
to allow for stretching.
The fiber they had at ours was thin single layer and squirrels chew it. Even
if they don't get to it weather damages them.

Shirona,
I'm a bit confused. Is there a relation between squirrels and cheap
fiber? Do squirrels prefer cheap fiber and expensive fiber?
Cheers,
