Turning the Optical Output Off and On
When the interface is XFP or SFP, you can turn the optical output (laser) off and on.
You can force the link of the device under test down or up.
Linkdown Transmission Continuation
When Manual has been selected in the Test menu and the interface is XFP, you can choose to
continue or stop transmission during linkdown detection.
Sync Loss Detection of 66 Bits Blocks
When the interface is XFP, the AQ1300/AQ1301 detects the condition when the signal reception
changes from a block sync (block lock) state of 66 bits blocks to a loss of sync (block lock loss) state
as defined in IEEE802.3. When a sync loss of 66 bits blocks is detected, the link is disconnected. This
feature is supported in firmware version (FW Ver.) R1.08.01.001 and later.
66B Sync Error Detection
When the interface is XFP, the AQ1300/AQ1301 detects 66 bits blocks whose sync header (2 bits) is
except 00 or 11 when signal reception is in a sync (block lock) state as defined in IEEE802.3.
This feature is supported in firmware version (FW Ver.) R1.08.01.001 and later.
66B Sync hi-ber Detection/Clear
When the interface is XFP, the AQ1300/AQ1301 detects and clears 66B Sync hi-ber on the basis of
the following conditions when signal reception is in a sync (block lock) state as defined in IEEE802.3.
This feature is supported in firmware version (FW Ver.) R1.08.01.001 and later.
Detection: When 16 or more sync headers (2 bits) set to 00 or 11 are detected in a 125 μs window
when signal reception is in a sync (block lock) state as defined in IEEE802.3.
Clear: When less than 16 sync headers (2 bits) that are not set to 01 or 10 are detected in a 125
µs window when signal reception is in a sync (block lock) state as defined in IEEE802.3.
Note
IEEE802.3 defines the sync (block lock) state of 66 bits blocks as follows:
Detection: When 64 consecutive sync headers (2 bits) set to 01 or 10 are received correctly.
Clear: When 16 sync headers (2 bits) that are not set to 01 or 10 are detected within 64 sync headers in a
sync (block lock) state.
Link Setting Acquisition
If the interface is SFP(GbE) or RJ-45, this feature is used to check the link settings of the DUT (the
device on the user side). You can acquire and display link setting information of the other device
connected to the AQ1300/AQ1301 or the DUT connected to the AQ1300/AQ1301 on the slave side
as well as the status of the differences in the negotiation settings. In addition, you can check the UTP
cable condition and display the results.
