The optical attenuators are designed for use with FC connectors.
Attenuators ordered with option 021 have straight connector interfaces.
Attenuators ordered with option 022 have angled connector interfaces.
The option 009 single-mode fiber optical switches have angled FC/APC
connectors with narrow keying.
The tunable lasers are designed for use with FC connectors.
Lasers ordered with option 071 have straight connector interfaces.
Lasers ordered with option 072 have angled connector interfaces.
The N7751/2A power meter ports also use FC connectors but are non-
contact. They can be used with both angled and straight connectors.
The N7766A and N7768A multimode attenuators have straight
connector interfaces. The fiber option determines the dimensions of the
internal fiber core, such as 50 or 62.5µm. Best performance is achieved
by matching this to the fibers used in the setup.
The option 062 multimode switches have straight FC/PC connector
interfaces. The dimensions of the internal fiber core is 62.5 µm. The
switches may also be used with good results together with 50 µm core
fiber because the fiber path is short.
If the connectors on your attenuator or lasers are angled, you can only use cables
with angled connectors with the instrument.
If the connectors on your attenuator are straight, you can only use cables with
straight connectors with the instrument.
Figure 20 Angled and Straight Connector Symbols
The above figure shows the symbols that tell you whether the optical
connectors of your instrument are angled or straight. The angled
contact connector symbol is colored green.
