4 GigE Test Procedure The Gigabit Ethernet Test Procedure consists of a Connectivity & Link Initialization test, Bit Error Rate (BER) Test, and RFC2544 test for Native Ethernet Service accessed at an optical GigE interface (1000BaseSX or 1000BaseLX). Test 1: GigE Connectivity Steps to complete the Connectivity Ethernet Link Initialization Test follow: Step Action 1 In the menu at the top of the Main screen, select TEST. Then select Ethernet>1GigE Optical>Layer 2 Traffic> Terminate. 2 Using the drop-down menus above the Left Results Window, set the Left Results Category to Summary/Status and the Right Results Category to Ethernet/L2 Link Stats. 3 Tap the SETUP button on the top right side of Main screen. A set of Setup tabs is displayed, including Interface, Ethernet, and Traffic. Tap INTERFACE to display the Interface setup tab JDSU. All Rights reserved

5 4 On the T-BERD 8000: Tap the SIGNAL tab within the Interface setup to view the Laser Wavelength. Select the proper wavelength for the line under test (850, 1310, or 1550 nm). On the T-BERD 6000A: Tap the CONNECTOR tab within the Interface setup to view Optical Connector status. Select the port that the desired SFP is installed in, as labeled on the side of the unit: SFP1 or SFP2 Select the tab corresponding to that connector. SFP specifications will be displayed, including Wavelength, Rates, Max Rx Level, and Vendor. Verify that the SPF is appropriate for the Line under test: 850nm for Multimode fiber, 1310nm or 1550nm for Single mode fiber. 5 Tap the PHYSICAL LAYER tab within the Interface setup to view Auto Negotiation and Flow Control options. Set the options as follows: Auto Negotiation On FDX Capable Yes HDX Capable Yes Pause Capable Both Rx and Tx Pause Length (Quanta): JDSU. All Rights reserved

6 6 Clean and Inspect a fiber optic jumper cable and connect the T-BERD GigE TX and RX ports to the proper GigE ports for the line under test. Use yellow fiber for a single mode 1310nm or 1550nm SFP and orange fiber for a multimode 850nm SFP. Tap the RESULTS button on the top right side of the screen to get back to the Main screen. 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.
