Fiber optic connection to switch has no internet
Power cycling or restarting your ONT (Optical Network Terminal) often resolves simple troubleshooting internet issues. Use the table below to see expert-recommended first steps for fiber troubleshooting. First, check the basics—look for power issues on your optical network terminal and inspect all cables for visible damage. Many fiber internet problems come from dirty connectors or loose plugs, not major faults. Your fiber optical network terminal (ONT), modem, or gateway provides LEDs letting you know the status of your internet (wide area network, or WAN) and home network (local area. We have a fibre run, SM, 650 meters, with Level1 dumb switches at each end, I get Link lights at both ends, but there's no network traffic.

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.
