While many current video deployments are using newer digital transmission systems; legacy analog systems are still relevant and less expensive than their more current counterparts. Thor Fiber now has a full line of less expensive, commercial grade Video Over Fiber systems in easy to use kits. Electronic and optical adjustments are never required with these automated plug and play units. LED indicators are provided for instant monitoring of the system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environments. Compatible with AHD-H, AHD-M, AHD-L / HD-TVI 720P & 1080P / HD-CVI 720P & 1080P. The optical module and core circuit are high-quality commercial level components that have unparalleled stability, and all optical & electrical interfaces match or exceed international standards. TVI you can shop around because it is an open platform. The TVI (Transport Video Interface) will become the new analog. It is backward compatible with analog cameras and is available in 720P or 1080P versions. The TVI 1080P version is backward compatible with TVI 720P.

I would suggest a different unit, H-1HD-1D-TVI-TX/RX - CVBS/TVI - over fiber.
It definitely supports Black Burst analog reference signal, and it should also support Tri-Level,because Tri-Level is very similar to Black Burst.
We have tested the same unit, H-1HD-1D-TVI-TX/RX, with Word Clock signals at rates of 44.1kHz, 48kHz, 88.2kHz, and 96kHz, and it passes accurately.
So, you can definitely use it for Word Clock signal over fiber applications.
