Connections CWDM Mux/Demux right; CWDM Add/Drop Mux far right: CWDM Connections The figure below shows Lantronix CWDM Mux/Demux & Add/Drop Mux modules. In the figure, λ1 indicates Lambda 1 (for one particular wavelength). 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. 3. Verify the install process. 4. Troubleshoot connected network devices to point to the switch. 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 transmitter optical output power and receiver optical sensitivity values. 6. See the FOA.org Testing & Troubleshooting Fiber Optic Systems webpage. 7. Record device information and Contact Tech Support.
