Fiber optic modem (ONT): Most fiber connections require an Optical Network Terminal (ONT), provided by your ISP. Compatible router: Verify that your router supports fiber optic input (look for an SFP or WAN port labeled "ONT" or "Fiber"). There are often labelsor symbols on it that indicate where to plug in the cable. Technically s/pdif or toslink are standards for fiber. Regulars know. In addition to the various port styles available for the HFBR-0400Z series products, there are also several extra options that can be ordered. To order an option, simply place the corresponding option number at the end of the part number. See Available Options for available options. These ports are designed to accommodate the unique characteristics of fiber optic cables, which transmit data using light signals rather than electrical.
