The fiber termination box provides a fiber-optic cable connection to the weather station. The fiber termination box supports point-to-point fiber networks, with single-mode or multimode cables.
Inside the weather station enclosure, the fiber termination box is connected with a cable to the small form-factor pluggable (SFP) module in DME801 plug‑in module. Currently, the station supports one SFP module, but support for a second SFP module will be offered in the future.
