Replace RF with a physical optical fiber link to achieve stable HD transmission, ultra-low latency control, and strong immunity to EMI / RF-contested environments.
A complete Fiber Optic Tether System is composed of Air Unit (Sky End), Ground Unit (Ground End), and a fiber optic reel/spool designed for controlled payout.
Role: Converts electrical signals to optical for transmission.
Interfaces: Video / Ethernet / Control (customizable).
Design: Lightweight for UAV payload constraints.

Role: Converts optical back to electrical outputs.
Outputs: Monitor / Terminal / Network / Control devices.
Use: Field operations & mission integration.

Choose the reel first: deployment speed + fiber length decide the reel/drum structure.
Match interfaces: confirm video/Ethernet/control requirements for Air/Ground modules.
Plan integration: payload weight, mounting space, and connector standard (FC/LC/SC).
