How to test fiber optic attenuation on a switch
The jumper method is the most accurate way to measure attenuation or end-to-end signal loss over a fiber optic cable. Specific installation or protocols will require stricter limits. This note also provides background information on system link configurations, test equipment and system component considerations that influence. When it comes to testing fiber optic cables, an Optical Time-Domain Reflectometer (OTDR) is an essential tool. It provides an in-depth analysis of the fiber network, helping technicians identify faults and issues like attenuation. The fiber optic link attenuation is tested using an optical loss test set (OLTS) or a light source and power meter (LSPM) Figure 1). This type of testing is the most accurate testing available. In the Privileged EXEC mode of the switch, use the show fiber-ports-optical-transceiver command by entering the following: interface interface-id - (Optional) Specify an Ethernet port ID.
