5.2 Measuring Optical Transceiver Module
This section explains how to measure 56G optical devices using the
MP1800A and MP1861A/MP1862A.
CAUTION
Check that the output level of the DUT (O/E) matches the
data input range for MP1862A. If it is out of range, adjust
the input level to MP1862A using an attenuator.
The equipment used in the following example is:
MP1800A-016: 1
MU183020A-x01/x23/x31: 1
MU183040B-x01/x20: 1
MU181000A: 1
MU181500B: 1
MP1861A-x01/x13/x30: 1
MP1862A-x01: 1
1. Place the equipment in the error-free state according to the
procedure in 5.1 “Achieving Error-Free Data Transmission”.
2. Turn off the output from MP1861A by clicking the
Output
module
function button (
) or pressing the
Output
key on the front panel
of MP1800A.
3. On the
Data Interface
tab of MP1861A, set the data output interface
so that it does not exceed the input voltage range of the DUT (E/O).
4. On the
Pattern
tab of MU183020A, select a test pattern for the Tx
side.
Once a test pattern is set for a channel of MU183020A, the set test
pattern is reflected to all the channels.
5. On the
Interface
tab of MP1862A, set the data input interface so
that it can detect the signal output from the DUT (O/E).
6. On the
Pattern
tab of MU183040B, select a test pattern for the Rx
side.
Once a test pattern is set for a channel of MU183040B, the set test
pattern is reflected to all the channels.
7. Turn off the power to MP1861A, MP1862A and MP1800A.
8. Connect MP1861A, MP1862A and DUT by using applicable coaxial
cables or equivalent.
Before connecting the DUT, short the cores and outer conductors of
the cables by using a thin pointed metal stick such as tweezers.
Connect the equipment as shown in Figure 5.2-1.
