Can I do dual port
testing from a
single SFP?
Dual port testing is an option on the 5802P and 5812P instru-
ments only. On these units, two SFP jacks are provided to
allow you to insert transceivers for different line rates or wave-
lengths without swapping SFPs. This minimizes wear and tear
on the SFPs.
RFC 2544 test
button does not
appear
If the RFC 2544 Test button does not appear on the Main
screen, verify the following:
– Payload analysis is ON for your current test application.
You can not run the automated RFC 2544 when the
instrument is configured to analyze live traffic.
– Traffic is not VPLS or MPLS encapsulated. You can not
run the RFC 2544 tests with VPLS or MPLS encapsulated
traffic.
– The instrument is not configured to run a multiple streams
Ethernet test.
– The instrument is not configured to run a timed test. You
can not run the RFC 2544 test during a timed test.
Maintaining
your instrument
The following section addresses questions that may be asked
about maintaining your instrument.
How often does the
instrument need to
be calibrated?
The T-BERD ⁄ MTS 5800 must be calibrated every 36
months.
What are the
recommended
insertion rates for
all components?
Each SFP or XFP transceiver can be inserted into the jacks
provided up to 100 times. More insertions may be possible,
but after 100 times, the pluggable optic should be checked.
