Tyco Electronics’ High Performance In

Line Attenuators utilize a unique all fiber

construction to absorb the optical signal.

By employing a Tyco Electronics’

technology, the design minimizes

reflectance, attenuation tolerance and

PDL while maximizing reliability, envi-

ronmental stability, and power handling.

There are no filters, air gaps, or core

mismatches.
