T-BERD®/MTS-5800 Network Tester
One Way Delay (OWD) Measurement
This document outlines how to set T-BERD/MTS 5800’s to measure One Way Delay on Ethernet
datalinks at rates up to 100Gbps.
Equipment Requirements:
•Two T-BERD/MTS-5800’s equipped with
the following:
oBERT software release V27.0 or greater
oTest options:
▪Ethernet and One Way Delay:
▪C510M1GE and C5OWD for 1Gigabit
or less
▪C510GELAN and C5OWD for 10Gig
▪C525GE and C5100GOWD for 25Gig
▪C540GE and C5100GOWD for 40Gig
▪C5100GE and C5100GOWD for
100Gigabit Ethernet
▪GNSS/GPS (VIAVI Part# C5GNSS)
•GNSS Antenna (Taoglas AA.171,
VIAVI Part# C5ANTENNA)
•SFP, QSFP, or CFP4 optical transceiver to
match the line under test
•Jumper Cables to match the optical
transceiver and the line under test
•Fiber optic inspection microscope
(VIAVI P5000i or FiberChek Probe)
•Fiber Optic Cleaning supplies
Figure 1: Equipment Requirements
The following information is required to configure the test:
•Physical Interface (10/100/1000BASE-T, 1000BASE-LX, 10GBASE-LR, 100GBASE-LR4, etc.)
•Auto Negotiation settings of the port under test
•VLAN ID (if encapsulation = VLAN)
Fiber Inspection Guidelines:
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect the jumper cable
or loopback plug before connection to
the optical transceiver.
•Focus the fiber on the screen. If dirty,
clean the connector.
•If it appears clean, run inspection test.
•If it fails, clean the fiber and re-run
inspection test.
•Repeat until it passes.

Connect Each T-BERD to Port Under Test:
1. For copper 10/100/1000BASE-T interface
testing with the T-BERD/MTS 5800v2 or T-
BERD/MTS 5882, connect the Port 1
10/100/1000 RJ-45 jack to the port under
test using CAT 5E or better cable.
2. For copper 10/100/1000BASE-T interface
testing with the T-BERD/MTS 5800-100G,
insert a copper SFP into the Port 1
SFP+/SFP28 slot and connect to the port
under test using CAT 5E or better cable.
3. For optical interfaces:
•Insert desired SFP, QSFP, or CFP4 into
the Port 1 slot on the top of the
T-BERD/MTS.
•Inspect and, if necessary, clean all SFPs,
fibers, and bulkheads, as described on
page 1.
4. Connect the SFP, QSFP, or CFP4 to the port
under test using a Single Mode or
Multimode jumper cable compatible with
the interface under test.

Launch and Configure Tests:
1. Press the Power button to turn on the
test set.
2. Enable the Timing Expansion Module (TEM)
or Internal GNSS Receiver and complete a
survey, as documented in “T-BERD®/MTS-
5800 Network Tester, Enabling the GNSS/GPS
Receiver for Sky Plot, One-Way Delay, and
Sync Measurements” Quick Card.
3. Using the Select Test menu, Quick Launch
menu, or Job Manager, launch an
Ethernet, Layer 2 Traffic, Terminate test on
port 1 for the desire physical interface. For
example: Ethernet►10/100/1000►
Layer 2 Traffic►P1 Terminate.
4. If the test is not in the default settings, tap
the Tools icon , and select
.
Press to continue.

5. Verify that the ToD Sync and 1 PPS Sync
LEDs are both green. If they are not green,
check your TEM or GNSS Receiver Setup.
6. Press the Setup Soft Key, to display
the Interface settings tab.

7. If you are testing a 10/100/1000 Electrical
or 1GigE Optical tests with auto negotiation
disabled, select the Physical Layer tab and
configure settings to match the Ethernet
port under test.
8. Select the GPS/CDMA tab and tap (check)
the checkbox to Enable GPS Receiver.

9. Select the Ethernet tab to configure
Ethernet settings.
•Tap [ DA ]to display the Destination
MAC Address. Enter the MAC Address
of the T-BERD/MTS at the far end of the
line under test.
•Tap [ SA ] to display the factory
default Source MAC Address of your
T-BERD/MTS. Provide this address to
the operator of the other T-BERD/MTS,
upon request.
•If you are testing a port that requires
VLAN encapsulation, set Encapsulation
to VLAN, tap [ VLAN ] and enter your
VLAN ID.
•If you wish to measure Bit Error Rate,
tap [ Data ] and set Acterna
Payload to BERT.

12.For 1GigE to 100GigE optical tests, select
the Laser tab in the Action panel, and press
. The button will turn yellow and be
relabeled .
13.A green Signal Present LED ● indicates the
T-BERD/MTS is receiving an optical signal
from the port under test. Green Sync
Acquired and Link Active LEDs indicate the
T-BERD/MTS has successfully connected to
the port under test and the link is active.

14.Tap the Actions tab and tap the Start Traffic
button . The button will turn yellow
and be relabeled .
15.Instruct the operator of the other
T-BERD/MTS to also Start Traffic.
16.Press the Restart Soft Key on the right
side of the screen. Verify that:
•The Right Results window shows “Rx
Mbps, L1” is approximately equal to
the CIR.
•The Right Results window shows Lost
Frames = 0.
17. Allow the Test to run for the desired
duration. Verify that the Left Result
window displays “ALL SUMMARY RESULTS
OK” throughout the test.
