The D-shaped adapter type are held magnetically for quick adapter
change. The heads also include a removable 81624DD adapter ring for use
with the threaded type adapters. The heads are connected to the N7749C
optical head interface.
Following are the benefits of using 8162-C optical power heads:
• Low relative uncertainty reduces the impact of connectorizing and fiber
handling and leads to a robust test setup
• The 5 mm large-area detector is less susceptible for connector
misalignment and guarantees highly repeatable measurement results.
Lower power per mm² makes the optical head more suitable for high
power measurements and guarantees better linearity.
