8 Ch SD/HD 3G-SDI Over Single Fiber with LOOP OUTPUTS

This unit utilizes direct conversion from electrical 3G SDI to optical CWDM wavelengths, with each signal being multiplexed on its own designated light wavelength.

 It supports all video formats, including both HDR and SDR, as 3G SDI handles both formats, and we are simply passing the signal through. 

So, the short answer is YES—we have them in stock and can ship today if required.

SDR (Standard Dynamic Range) and HDR (High Dynamic Range) are  video standards or formats that define the way brightness, contrast, and color are handled in video signals.

How to Name SDR and HDR Correctly:

1. SDR (Standard Dynamic Range):
   Refers to the traditional method of representing video, where the range of luminance and color is limited compared to HDR.
   • It's not a protocol but rather a display standard.
2. HDR (High Dynamic Range):
   Refers to a method of displaying video with a much wider range of brightness and a broader color gamut than SDR.
   • It's not a protocol but a set of standards or formats.
   • Common HDR formats include:
     • HDR10: The most widely used open HDR format.
     • Dolby Vision: A proprietary format developed by Dolby, offering dynamic metadata for scene-by-scene brightness adjustment.
     • HLG (Hybrid Log-Gamma): A format designed for backward compatibility with SDR displays, often used in broadcast.
     • HDR10+: An improvement over HDR10 that includes dynamic metadata like Dolby Vision but is open and royalty-free.

   • SDR (Standard Dynamic Range):

     SDR refers to video content with a standard brightness and color range.

   • Brightness Range: Limited to about 100 nits (a measure of luminance).
   • Color Gamut: Uses standard color spaces, such as Rec. 709, which is sufficient for most traditional displays.
   • Applications: SDR is suitable for most existing TV broadcasts, online video streaming, and traditional production environments.

     HDR (High Dynamic Range):

     HDR is an advanced video format that offers a wider range of brightness, contrast, and color than SDR.

   • Brightness Range: Can reach up to 1,000 nits or more, allowing for much brighter highlights.
   • Color Gamut: Supports wider color gamuts, such as Rec. 2020, for more vivid and accurate color reproduction.
   • Benefits:
     • Enhanced contrast: Greater detail in both shadows and highlights.
     • More lifelike colors: Allows viewers to see images closer to what the human eye perceives in real life.
   • HDR Standards: There are several HDR standards, such as HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision.

     Why Use SDI for 1080p SDR and HDR?

   • SDI can carry uncompressed high-definition signals, making it ideal for maintaining the highest video quality during production.
   • For HDR, SDI is preferred because it can handle the increased data rate required for wider dynamic range and color.
   • SDI connections also support embedded audio, meaning audio can be transmitted along with the video in the same cable.

     Key Differences Between SDR and HDR

     Aspect	SDR	HDR
     Brightness	Up to 100 nits	Up to 1,000 nits or more
     Color Gamut	Rec. 709	Rec. 2020 or DCI-P3
     Contrast	Standard	Enhanced (better shadow & highlight detail)
     Visual Impact	Good for most displays	More immersive, lifelike images
