Fiber (Multi Mode) |
 |
| |
The design of multimode fiber consists of a germanium doped core and a silica
cladding. A dual protective acrylate coating is applied over the fiber cladding
to cushion the fiber against microbending losses, provide abrasion resistance,
and preserve the mechanical strength of the glass.
Each fiber is proof tested so that it will survive installation loads and
associated longterm residual stresses, even under extreme environmental conditions.
Finally, each fiber is measured for optical and dimensional properties for
compliance with all specifications listed in the respective fiber data sheets. |
