Tap the Laser/TX Signal Tab at the bottom left of the Main screen, then tap the Laser Off button to turn the laser on. An Optical Attenuator may be required on the receiver if the receive level exceeds the Maximum Receive Level of the SFP. The T-BERD will alert you of this need as follows: 7 Tap the RESTART button on the Right side of the display to reset test results. Verify that Status, Signal Present, Sync Acquired, and Link Active LEDs are green on the left side of the display. Green LEDs indicate local Ethernet Connectivity is established and that Test 1: GigE Connectivity has passed. Proceed to Test 2: GigE BER Test. 8 If the Status, Signal Present, Sync Acquired, and Link Active LEDs are not all green,, tap the Laser On button to turn the laser off, then verify the following: The T-BERD Setup is correct, as outlined above. The Laser is on in the Network Element. The Network Element is setup for Auto Negotiation. The Network Element supports the same fiber type (Single Mode vs. Multimode) and wavelength (850nm, 1310nm, 1550nm) as the T-BERD. Optical cables are good quality and are properly connected. Tap the Laser Off button to turn the laser back on. If the Status, Signal Present, Sync Acquired, and Link Active LEDS are still not all green, Test 1: GigE Connectivity has failed.
