Step Action Details
1. Power On Press the ON/OFF button to turn on the T-BERD 5800. Wait
approximately 2 minutes for the Base Unit software to load.
2. Insert SFP For optical testing, insert desired SFP (1000BASE-SX, 1000BASE-LX,
or 1000BASE-ZX) in the desired T-BERD 5800’s SFP port.
3. Clean & Inspect While the BERT module is starting up, and before connecting to an
optical link, make sure the fiber and connector are clean using a Fiber
Inspection probe.
4. Connect Connect the Ethernet test port on the top of T-BERD 5800 to the
Ethernet switch port under test.
Use Orange Multimode jumper cables for 850 nm 1000BASE-SX.
Use Yellow Single Mode Fiber jumper cables for 1310 nm
1000BASE-LX and 1550 nm1000BASE-ZX.
