Performance Tests
STM-1/STM-4 Optical Interface (Options 130, 131)
errors in back-to-back mode at 1310 nm (and 1550 nm wavelengths if Option 131).
The Protected Monitor Point (PMP) functionality is verified by looping the HP
37717C Optical Output to the PMP input via an Optical Attenuator and Optical to
Electrical Converter, then checking for error-free operation with identical Tx and Rx
patterns selected. The specified electrical level for the PMP input is obtained by
adjusting the optical signal level to the O/E Converter using the Optical Attenuator.
Equipment Required
WARNING 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.
Procedure Option 130 and 131
1. Connect the HP 37717C 1310 nm Optical Out Port to the HP 8153A (ensure that
all connections are tight and that the cable has no twists).
