3.3 Measuring Multichannel Optical Module Bit Error
Rate
This section explains the CFP4 module measurement method as an
example of multichannel optical module.
The CFP4 module contains four pairs of transmitters and receivers. With
the MP2110A-014, the CFP4 module bit error rate can be measured for
four channels simultaneously.
If using a separate CFP4 for transmission in addition to the DUT CFP4,
connect as follows. Use coaxial cables of the same length as for between
Data Out and
Data
Out to connect the BERTWave and CFP4. Bit error
rate cannot be measured correctly if different length coaxial cables are
used.
