The Thor Fiber F-GL-SYNC-TX/RX is a compact optical extender designed to transport precision broadcast timing signals over single-mode fiber. It transparently carries Genlock, Black Burst (bi-level), and Tri-Level sync while preserving signal integrity and phase stability over long distances. Ideal for studio, OB, and remote production environments, the unit supports professional sync generators (including BMD) for SD and HD formats such as 1080i50. With plug-and-play operation, SFP optics, and a mini form factor, it provides reliable, interference-free timing distribution where copper cabling is distance-limited or electrically noisy.
