Troubleshooting 

1.

 

Make sure the fiber connectors are clean; see the

 

FOA.org

 

termination cleaning webpage. 

2.

 

Make sure your model supports the feature or function attempted; see 

Ordering Information 

on page 

4

.  

3.

 

Verify the install process; see 

Installation

 on page 

9

. 

4.

 

Troubleshoot connected network devices to pinpoint the problem to the switch. See the related documentation. 

5.

 

When calculating optical loss, ensure that the total loss, plus a safety factor (typically 3dB) does not exceed the 

optical power budget (the difference between the transmitter optical output power and the receiver’s optical 

sensitivity). See the equipment manufacturers’ documentation for the transmitter optical output power and receiver 

optical sensitivity values. 

6.

 

See the 

FOA.org Testing & Troubleshooting Fiber Optic Systems

 webpage.
