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:
o BERT software release V27.0 or greater
o Test 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
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.
