HDMI Extender by single-mode fiber optic LC 20Km simplex

HDMI (High-Definition Multimedia Interface) is a digital interface standard designed for the simultaneous transmission of uncompressed audio and video streams from a compatible source to a digital display or receiver.

This interface employs Transition-Minimized Differential Signaling (TMDS) to maintain data integrity at high frequencies. Throughout its revisions, HDMI has evolved from a basic digital video solution into a complex data bus capable of carrying 4K signals at 60Hz, dynamic metadata, and bidirectional control protocols between devices.

The mass adoption of the HDMI standard has transformed the interconnect architecture in multimedia data centers and high-performance workstations. Its ability to integrate Audio Return Channels (ARC/eARC) and Ethernet connectivity (HEC) has drastically simplified structural cabling, eliminating the need for multiple redundant analog and digital cables while ensuring signal integrity over significant distances through active equalization.

CEC Control and Multi-Streaming Integration

A critical innovation in version 2.0 is the ability to deliver simultaneous dual video streams on the same screen and up to four independent audio streams, optimizing bandwidth for multi-user applications.

Key Advantages

• Pure digital transmission avoiding D/A signal degradation.
• Full backward compatibility across all standard versions.
• Native support for high-resolution audio formats like Dolby TrueHD and DTS-HD.
• Support for 21:9 cinema aspect ratios and dynamic lip-sync.

Note: Final interface performance is dependent on the cable certification (Standard, High Speed, or Premium High Speed).

1080p, also known as Full HD, refers to a video resolution of 1920x1080 pixels using progressive scanning.

Detail

The 'p' stands for progressive scan, which eliminates the flickering often associated with interlaced video (1080i).

Advantages

• Superior image clarity for mainstream displays.
• Widely supported by all streaming platforms.

Note: 1080p remains the industry standard for high-definition quality.

• FLAT or plane: It is used in multimode installations and its cut is flat. The return loss oscillates in <-30db.
• PC or Phisical contact: It was usedin single-mode and multi-mode installations. It is the most common polishing in fiber facilities.
  Its polishing is convex and it has the best properties of loss of return, between <-35db.
  Its connector is blue.
• UPC or Ultra Phisical Contact: Used for single-mode fiber installations. It is equal to the polished PC, but it does not reflect as much light as the polished PC.
  Your return loss is around <-55db. It is a polish usedin digital systems and telephony installations.
  Its connector is Blue.
• APC or Angled Physical Contact: This is an 8 degree angular polish. With a loss return of <-65db.
  Its connector is green.

• Single mode (single mode): Only one mode light propagates. Allow distances up to 400 km and very high speeds. The usual size of 9/125 microns fiber is.
• Multimode (multi mode): The light is spread by more than one way. . Used for transmission at close range, no more than 2 Km Typical multimode fibers are according to ISO: OM1 (62., Data transmission is changing direction. In a duplex system, each of the fibers is used for transmission in one direction. Therefore, the duplex installations are faster and more efficient.
