- As pure silica glass with no impurities
is used as a core for the compound-glass-fiber-compatible
fiber, attenuation is less than half that with the compound-glass
fiber, enabling data transmission with improved system margin
and higher reliability.
- Use of pure silica glass instead of inherently
weak compound glass and reinforcement with hard polymer
cladding result in mechanically strong, reliable fiber cords
and cables.
- Highly accurate connector attachment is
possible with no cumbersome and skill-requiring polishing
process (only cleaving with the special cutter is required).

*1: |
In cases where cable length needs to be
200 m or more, or if a great tension will be applied to the
cable during laying, such as when pulling the cable with a
winch, use a multi-type optical fiber cable with center tension
member. |
*2: |
A LAP-sheathed cable must be used even for indoor use
if a cable is anticipated to be soaked or immersed in water. |
