Quick Card
T-BERD®/MTS-5800 Network Tester
CPRI Check, Dark Fiber and WDM Loopback Testing
This quick card describes how to verify that a dark fiber or CWDM/DWDM front-haul link will support
error-free CPRI transport at a given line rate, using the T-BERD 5800v2 and a hard loop.
Figure 1: CPRI Front-haul Network Topologies
Equipment Requirements:
•T-BERD/MTS-5800v2 equipped with:
oBERT software release V26.2 or greater
oCPRI test options:
▪C512GCPRI for CPRI Rate 2 (1228.8M)
▪C524GCPRI for CPRI Rate 3 (2457.6M)
▪C549GCPRI for CPRI Rate 5 (4915.2M)
▪C598GCPRI for CPRI Rate 7 (9830.4M)
•SFP or SFP+ optical transceiver that supports
the CPRI rate for the fiber under test
•Single mode jumper cable to connect the T-
BERD to the fiber under test
•Single mode loopback plug or jumper cable to
loopback the fiber under test
•Fiber optic inspection microscope
(VIAVI P5000i or FiberChek Probe)
•Fiber optic cleaning supplies

Information Requirements:
•CPRI Line Rate
•Pass/Fail Criteria:
oMaximum and Minimum Optical Receive Level for looped-back signal
oMaximum Round Trip Delay for fiber under test

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.
Figure 3: Inspect Before You Connect (IBYC)
Connect to Fiber Under Test:
1. Insert CPRI optics into the Port 1 slot on the
top of the T-BERD/MTS 5800.
2. After inspecting the fiber end faces, connect
the SFP/SFP+ to the fiber under test using an
LC-LC jumper cable.
3. Loopback far-end of fiber under test using a
Single mode Loopback plug or Jumper Cable.
