Equipment Required

Power Meter
Power Meter Sensor Module
FC/PC Connector Interface
Optical Attenuator
Optical Cables (Qty. 2)
Safety precautions must be observed when handling the HP 37717C Optical
Modules as these generate laser signals which can cause serious injury. The
guidelines below must be followed;
• Check the connector configuration of the Fiber Optic Interfaces. If these are fitted
with a connector interface other than FC/PC then remove the existing connector
interface and fit the FC/PC connector interface.
• Check for any damage to the HP 37717C Fiber Optic Interface spring loaded
aperture covers and connectors. Do not power up the instrument if in any doubt
about the integrity of these connectors.
• Make all connections to the HP 37717C Fiber Optic Interfaces before powering
up the instrument.
