T-BERD®/MTS-5800 Network Tester
Ethernet 4x10GigE Layer 2 Traffic Loopback
This document outlines how to set the T-BERD/MTS 5800 up as a Layer 2 Traffic Loopback device
across a Link Aggregation Group (LAG) with up to 4 10GigE links.
Equipment Requirements:
•T-BERD/MTS-5800 equipped with the
following:
oBERT software release V29.1.1 or
greater
oEthernet test options:
▪C510GELAN for 10 Gigabit Ethernet
▪C54x10GELAN for 40 Gigabit
Ethernet
o40GBASE-SR4 or 4x10GBASE-LR4 QSFP+
optical transceiver to match the line
under test
•MPO to LC fanout Cable to match the
optical transceiver and line under test
(Single mode or Multimode Fiber)
•Fiber optic inspection microscope with
MPO and LC tips (VIAVI Sidewinder)
•Fiber Optic Cleaning supplies
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Type of hash (Layer 2/MAC Address or Layer 3/IP Address)
•Number of 10GigE LAN physical ports in the LAG
(2 for 20Gig service, 3 for 30Gig service, 4 for 40Gig service)
Fiber Inspection Guidelines:
•All fiber end-faces must be clean and pass
an inspection test prior to connection.
•Use the VIAVI Sidewinder microscope to
inspect both sides of every connection
being used (QSFP Port, Breakout Cable,
bulkhead connectors, etc.)

Connect to Fibers Under Test (FUT):
1. For optical interfaces:
•Insert QSFP+ Optical Transceiver into
the Port 1 slot on the top of T-BERD.
•Inspect and, if necessary, clean all SFPs,
fibers, and bulkheads, as described on
page 1.
•Connect the QSFP+ to the MPO to LC
fanout cable.
•Connect the LC fanouts to the 10GigE
LAN physical ports under test as
follows, per your work order:
▪Fanouts #1 and #2 for 20Gig service
▪Fanouts #1, #2 and #3 for 30Gig
service
▪Fanouts #1, #2, #3 & #4 for 40Gig
service

tapping the check boxes:
✓Select Port 1/Stream 1 and
Port 2/Stream 2 for 20Gig service.
✓Select Port 1/Stream 1,
Port 2/Stream 2 and Port 3/Stream 3
for 30Gig service.
✓Select Port 1/Stream 1 through
Port 4/Stream 4 for 40Gig service.
8. Tap OK to return to All Streams settings.
9. Tap the Results Soft Key, ,to view the
Results screen.

10. Select the Laser tab in the Action panel at
the bottom of the screen, and tap .
The button will turn yellow and be
relabeled .
11. Tap the Restart Soft Key , on the right
side of the screen.
12. Confirm that Signal Present, Sync
Acquired and Link Active LEDs are green ●
for each port in the LAG. A green Signal
Present LED indicates the T-BERD/MTS is
receiving an optical signal from the port.
Green Sync Acquired and Link Active LEDs
indicate that the T-BERD/MTS has
successfully connected to the port and the
T-BERD/MTS is ready to be looped up.
