Description

Genlock / Black Burst / Tri-Level Sync over Fiber Extender Kit

Keep every camera chain and production switch perfectly locked even when your sync reference has to travel far. The Thor Fiber F-GL-SYNC-TX/RX extends precision timing signals over single-mode optical fiber so remote gear stays frame-accurate and stable with your main timing source.

This mini kit transparently passes the most common broadcast reference formats, including Genlock, Black Burst (bi-level sync), and Tri-Level sync, making it ideal for modern HD workflows where clean timing is mandatory. It’s designed to work with professional sync sources (including BMD sync generators for 1080i50 environments) and preserves signal integrity over long runs—without drivers or software.

With a compact “integration-friendly” form factor, hot-pluggable SFP optics, and auto-sensing SD/HD sync status LEDs, it’s a simple, reliable way to distribute reference timing across campuses, OB setups, studios, and machine rooms where copper would be noisy, lossy, or distance-limited

Features

  • Passes timing protocols: Genlock / Black Burst (bi-level) / Tri-Level over fiber

  • Single-mode fiber up to 20 km for remote sync distribution

  • Mini size—available as enclosed units or PCB-style integration option

  • Hot-pluggable SFP, plug-and-play (no drivers)

  • BNC interface, 75Ω broadcast impedance, with TX loopout and multiple RX outputs

  • SD/HD auto sense with LED indication

  • Supports CVBS -Baseband Video PAL/NTSC
