MODEX units are fast modular extenders supporting AV and broadcast industry formats offering 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 cable.


MODEX units are tailor-made configurations where the actual device elements – video module, interface modules and media connector – are selected by the customer when ordering.

Built-in Proprietary Technologies

The technology built into MODEX extenders allow up to 30 meters of DVI cable on input and include Advanced EDID Management, Pixel Accurate Reclocking, LAN, RS‑232, RS‑422, USB control and many more.
The recently upgraded product now has improved cooling system, monitoring functions checking voltage and temperature realtime, and also separately checking the optical unit temperatures.

Graphical User Interface

MODEX Modular Extenders have their own built‑in websites for control with an advanced Graphical User Interface (GUI) allowing the user to control all the functions of both MODEX transmitters and receivers in an easy and user friendly way.
When a MODEX is connected to a controlling computer the user meets the MODEX Graphical User Interface. This GUI allows the user to control all the functions of both MODEX transmitters and receivers in an easy and user friendly way. The GUI is smart and intuitive and is also optimized for tablets. The EDID Manager, Frame Detector and advanced audio settings are also available from the GUI, with setup presets that can be pre-configured, saved and quickly applied.

Build Your MODEX to Best Serve Your Needs

Build Your MODEX

You need to select the frame, modules, interfaces and connectors for your application before ordering. Try the MODEX Builder, our online configurator for MODEX devices and send your tailor-made MODEX configuration instantly to order.

Select Your Media Connectors

Media Connectors

The OPTS and OPTM Media Connectors provide transmission over a one Single Mode (OPTS) or Multi Mode (OPTM) fiber. Most fiber connector types are available to choose the best option for your application such as Neutrik OpticalCON, industrial grade LC ODVA, ST, SC, HF4, EBCM, EBCJ or LEMO. For a cost-effective smart solution Lightware introduced the LC breakout Media Connector which allows the user to connect another MODEX extender with a patch cable at the end point to send signals to two MODEX units over a single Neutric OpticalCON duo cable. There are also two optional power connectors provided. The MODEX OPTx series provide a reliable optical connection powered by an internal power supply.

Select Your Video Modules

Video Modules

MODEX supports 4096x2160@30Hz 4K and 3840x2160@30Hz UHD resolutions and most video formats: DisplayPort 1.1, HDMI 1.4 with 3D, Dual‑Link DVI, SDI, and 3G‑SDI. The video format conversion is automatic if the two ends have different modules. External S/PDIF, RCA or the Embedded Audio present in different video signals are accepted as source. Embedding and extracting audio or transmitting in both directions simultaneously are also supported.

Select Your Interface Modules

Interface Modules

MODEX architecture allows the transmission of a wide variety of auxiliary signal types through its interface modules. All auxiliary signal types can be simultaneously transmitted at full bandwidth, reducing the need for additional extenders and cabling. MODEX frames have up to two module slots for interface modules, which can be any control signal, audio or Ethernet.
