Using a fiber-optic test cable, connect output of GigE test set to 10 dBm attenuator.
24
Set GigE test set for auto negotiation. See figures
Using a fiber-optic test cable, connect attenuator connected to GigE test set to RX port
25
of first GIGE module in shelf (Device Under Test). See figures
Connect power meter to TX port of first GIGE module in shelf.
26
Measure output power from GIGE module TX port. Power reading must be within
27
specification. (Refer to table 121-A.)
Disconnect power meter from GIGE module TX port.
28
Is an attenuator required between the GIGE module TX port and the GigE test set?
29
Using a fiber-optic test cable, connect appropriate attenuator to TX port of first GIGE
30
module in shelf. See figures
needed as interconnection between test set and incoming signal of all GigE physical
layer types.
Using a fiber-optic test cable, connect attenuator connected to GIGE module TX port
31
to GigE test set input connector. See figures
typical connections.
Using a fiber-optic test cable, connect output of OCn module test set to 10 dBm or
32
15 dBm attenuator. See figures
Using a fiber-optic test cable, connect attenuator connected to OCn module test set to
33
RX port of first OCn module in shelf (Device Under Test). See figures
through 121-4.
Connect power meter to TX port of first OCn module in shelf.
34
Measure output power from OCn module TX port. Power reading must be within
35
specification. (Refer to table 121-A.)
Disconnect power meter from OCn module TX port.
36
Is an attenuator required between the OCn module TX port and the OCn module test
37
set?

If yes, go to step 30.
If no, go to step 32.
121-1 and 121-2. In most cases, 15 dB attenuator is
121-2
If yes, go to step 38.
If no, go to step 41.
