Field calculators for network and RF work

Standards-based tools for people who have to make a link work, not just describe it. No sign-up, no app, nothing stored.

Power over Ethernet

Fibre optics

GPON and XGS-PON ODN loss against both ends of the ITU-T class window, with splitter cascades, both wavelengths and receiver overload.

In progress

Path loss, Fresnel clearance, earth curvature, rain attenuation and availability.

Insertion loss, NEXT and delay skew by category, length and temperature.
