Testing Connectivity of Cables

During the installation of the OptiX RTN 905E, the cables may be connected to service interfaces incorrectly, or the hardware may malfunction. To ensure that the services run properly, test connectivity of the cables.

5.9.1 Testing Connectivity of E1 Cables

By testing connectivity of E1 cables, you can check whether the E1 cables are properly connected between the equipment and the DDF, and whether the E1 cables are in the normal state.

Prerequisites

The equipment must be equipped with an E1 interface board, and the E1 port must travel through the DDF before being connected to another device.

Tools, Equipment, and Materials

Web LCT
BER tester

Procedure

At the DDF, connect the BER tester to the first E1 port of the IDU.
The BER tester displays the AIS alarm.

Set the corresponding E1 port to Outloop using the Web LCT.
- Select the PDH interface board in the Object Tree.
- In the Function Tree, choose Configuration > PDH Interface.
- Select By Function and select Tributary Loopback from the drop-down menu.
- In Tributary Loopback, select Outloop.
- Click Apply.
  The Confirm dialog box is displayed.
- Click OK.
Observe the BER tester.
The BER tester should not display the AIS alarm any more.
Release the outloop set in 2.
- Select the PDH interface board in the Object Tree.
- In the Function Tree, choose Configuration > PDH Interface.
- Select By Function and select Tributary Loopback from the drop-down menu.
- In Tributary Loopback, select Non-Loopback.
- Click Apply.
  The Confirm dialog box is displayed.
- Click OK.
Observe the BER tester.
The BER tester should report the AIS alarm.
Repeat 1 to 5 to test all the other E1 ports.

5.9.2 Testing Connectivity of Network Cables

By testing connectivity of network cables, you can determine whether the network cables are in the normal state.

Prerequisites

The network cables are already made.

Tools, Equipment, and Materials

Network cable tester

Background Information

You can also test the connectivity of a network cable by performing a loopback on the data ports (this method is applicable when the equipment is powered on). Specifically, use the network cable to be tested to connect any two data ports. If the LINK indicators of the two data ports turn on, it indicates that the network cable is in the normal state.

Procedure

Connect the network cable to the port of the network cable tester.

Crossover cable	The 1-8-G indicators turn on one after another.	The 3-6-1-4-5-2-7-8-G indicators turn on one after another.

Connect the network cable that passes the test to the Ethernet port of the device.

5.9.3 Checking Fiber Jumper Connection

During installation, the fiber jumpers may be incorrectly connected or the attenuation may be excessively high. As a result, services will fail to run properly. To prevent this situation, check the connection after the fiber jumper is routed from the optical interface to the optical distribution frame (ODF). This topic mainly describes how to test the fiber jumper connection by using an optical interface board.

Prerequisites

The fiber jumper is installed and routed from the optical interface to the ODF.
The equipment is powered on.

Tools, Equipment, and Materials

Optical power meter
Short fiber jumper

Precautions

DANGER:

When you are checking the connection of fiber jumpers, avoid direct eye exposure to the laser beams.

Connection Diagram

When you use an optical interface board to test the fiber jumper connection, connect the fiber jumper to the optical power meter on the ODF side and connect the fiber jumper to the TX port of the optical interface board on the chassis side. Figure 5-6 shows the connection.

How to run IF cable hardware test for RTN905-3010243-4

Procedure

On the chassis side, disconnect the fiber jumper from the OUT GE optical port.
Connect the optical power meter to the OUT GE optical port with a short fiber jumper.
Switch on the optical power meter and set the operating wavelength according to the type of optical interface. The measured launched optical power of the GE optical port is A.
Insert the fiber jumper back into the OUT port.
On the ODF side, disconnect the fiber jumper from the OUT port. Connect the fiber jumper to the optical power meter. The measured optical power is B.
Disconnect the fiber jumper from the OUT GE optical port. The optical power meter reads "LO" and does not receive any optical signals.
Compare the values of A and B.
- If the difference between A and B is less than 1 dB, it indicates that the fiber jumper is correctly connected and the attenuation of the fiber jumper is within the normal range.
- If the difference between A and B is more than 1 dB, verify that the fiber jumper is in good condition and is correctly routed. Then, verify that the fiber jumper terminal is clean.
NOTICE:
If the fiber jumper is connected through a flange, the difference between A and B should be less than 2 dB. Otherwise, it indicates that the fiber jumper is incorrectly connected or the attenuation of the fiber jumper is not within the normal range. Verify that the fiber jumper is in good condition and is correctly routed. Then, verify that the fiber jumper terminal is clean.
Repeat Steps 1 through 7 to check the fiber jumper that is connected to the IN port.
Restore the fiber jumper connections on the chassis side and the ODF side.
Repeat Steps 1 through 9 to check fiber jumper connections of other optical interfaces and then restore the connections when completed.
