The fiber is of Panda type, with TE mode in the slow axis in line
with the connector key. A well defined state of polarization
ensures constant measurement conditions.

PMF Output Connector
Angled Contact Connectors
The Agilent 81663A DFB Laser Source module is equipped with
an angled contact optical output connector as standard.
Angled contact connector helps you to control return loss. With
angled fiber endfaces, reflected light tends to reflect into the
cladding, reducing the amount of light that reflects back to the
source.
If the contact connector on your instrument is angled, you can only
use cables with angled connectors with the instrument.

Angled Contact Connector Symbols
Figure 4 shows the symbol that tells you the contact connector
of your tunable laser module is angled. The angled contact
connector symbol for an optical output equipped with a PMF is
colored green.
