Quick Overview

Insertion Loss and Link Loss Testing:
Paired with a TEMPO 555B or 558B optical power meter, the 266A
serves as an ideal general purpose 1550nm laser source for measuring
the insertion loss of single-mode fiber optic cables and connectors. The
266A can also be used with an optical power meter for link loss testing
of installed cable plants.

The 266A laser source is particularly useful for testing and maintaining
telecommunications systems and other long wavelength single-mode
fiber optic networks operating at 1550nm.

The 266A laser source is fitted with a precision Universal Connector
Interface (UCI), which ensures maximum accuracy and repeatability
when performing critical measurements on fiber optic systems. A compre-
hensive range of UCI adapters is available for all industry standard fiber
optic connectors.
