Application specific modular extenders with various video, audio, Ethernet, USB and I/O modules

Lightware Visual Engineering proudly introduces the MODEX family, the world’s best and fastest modular extenders supporting the AV and Broadcast industry’s formats. MODEX (Modular Extender) offers a full range of modular transmitters and receivers extending digital and analog video and audio, USB KVM, Ethernet and control signals over a single fiber or CAT5/6/7 cable. Customizing the MODEX is really simple:

Step1: Choose a MODEX frame
Step2: Choose a fiber or CATx Media connector
Step3: Select one video & audio module
Step4: Select two interface modules
Finish: Your MODEX is ready to use


The technology built into the MODEX family breaks many standard limitations allowing 30 meters DVI cable on input, Advanced EDID Management, Pixel Accurate Reclocking, LAN, RS-232, RS-422 and USB control, remote powering and more.

Available configurations:

  • Half RU MODEX front and rear view

The half unit extender allows one video & audio module and two interface modules (each can be the same or different type).

The front panel has an additional 10/100 Mbps Ethernet port (with full functionality, but can be used as control interface) and USB KVM connectors (transmitter has one USB-B for the computer; receiver has two USB-A connectors for the keyboard and mouse). Keyboard and mouse functions are emulated by the extender and no USB enumeration occurs while operator switching. A computer is not aware when a keyboard or mouse has been changed.

Half RU MODEX may either be a video transmitter or a receiver depending on the installed configuration.

Media connector

MODEX includes a family of long distance transmitters and receivers for sending and receiving video, audio, RS-232 and IR control, USB KVM and Ethernet over a single CATx or single fiber cable. Media connector, the heart of the MODEX determines the signal transportation type as well as the direction (the unit is a transmitter or receiver):


  • OPTS & OPTM Media connector

The OPTS and OPTM extenders (MODEX-OPTx series) give optical transmission over a single or duplex fiber. Equipped with a Neutrik OpticalCON or industrial grade connector (both can be used with LC fiber cable), the OPTS and OPTM provide a reliable optical connection and powered by an internal power supply.


  • TPS Media connector / under development

The TPS extenders (MODEX-TPS series) provide full functional transmission over a CAT5/6/7 twisted pair cable, equipped with Neutrik EtherCON connector that ensures a reliable RJ45 connection even in rental/staging environments. Common RJ45 connectors can also be used with Ethercon. MODEX-TPS is powered by an external power supply.

Video & Audio modules 

Various video formats are supported: video could be DisplayPort 1.1, HDMI 1.4 with 3D, Dual-Link DVI, SDI, 3G-SDI and analog VGA, Interlaced Composite Video. No matter, what kind of video format you have, your pixels will be extended by MODEX. The video format conversion is automatic if the two ends have different modules. The video & audio modules are also capable of transmitting audio. The source may be external S/PDIF, RCA, XLR or the embedded sound present in different video signals. Embedding and extracting audio or transmitting in both directions simultaneously is also supported.

  • DisplayPort input module - MODEX-AV-DP-IM
  • DisplayPort output module - MODEX-AV-DP-OM
  • 3G-SDI input module - MODEX-AV-3GSDI-IM
  • HDMI input module - MODEX-AV-HDMI-DVI-IM
  • HDMI output module - MODEX-AV-HDMI-OM
  • Dual-Link DVI input module - MODEX-AV-DVIDL-IM
  • Dual-Link DVI output module - MODEX-AV-DVIDL-OM

Interface modules 

Lightware’s innovative MODEX architecture allows each transmitter and receiver to support a wide variety of auxiliary signal types through the interface modules. All auxiliary signal types can be simultaneously transmitted at full bandwidth over fiber or twisted pair reducing the need for additional extenders and cabling. Both MODEX core modules have auxiliary interface slots (half RU has two module slots). It can be any control signal, audio or Ethernet:

  • Digital and analog audio input module - MODEX-IF-AUDIN
  • Digital and analog audio output module - MODEX-IF-AUDOUT
  • Digital and analog audio in/output module - MODEX-IF-AUD
  • RS-232 and IR module - MODEX-IF-RS232-IR
  • RS-232 and RS-422 module - MODEX-IF-RS232-RS422
  • Ethernet 10/100 Mbit module - MODEX-IF-ETH
  • RS-232 module - MODEX-IF-RS232
  • RS-232 double module - MODEX-IF-2xRS232

MODEX configurations

All MODEX extenders are produced according to the customer's specification. The ordered MODEX configuration’s identifier sets up from the module numbers:

MODEX Frame and Media connector are coherent parts in the MODEX family as they determine each other.

Available configurations for Frame and Media connector:

  • 9161 0103 – 9161 0227 : MODEX-OPTS-TX singlemode optical transmitter + Neutrik OpticalCON connector
  • 9161 0104 – 9161 0227 : MODEX-OPTS-RX singlemode optical receiver + Neutrik OpticalCON connector
  • 9161 0106 – 9161 0228 : MODEX-OPTM-TX multimode optical transmitter + Neutrik OpticalCON connector
  • 9161 0107 – 9161 0228 : MODEX-OPTM-RX multimode optical receiver + Neutrik OpticalCON connector

After selecting the needed Frame type and Media connector, any Video & audio and Interface modules can be connected to the above configurations, no restrictions are made. The MODEX modules are not hot swappable and are fix configurations, the ordered MODEX is custom manufactured by Lightware.

More configurations are coming soon as the development for the new modules are ready. Please see the Summary for the available modules.
