Ikelite 4401.3 Optical Slave Converter for DS Strobes (3rd Gen)

Product Details

Converts the electrical bulkhead of any Ikelite DS strobe into a fibre optic port.


This 3rd Generation of the Ikelite Fibre Optic Converter features a hard-anodized aluminium plug connection which reduces weight without sacrificing durability. It is recommended for use with any Ikelite strobe produced in September 2018 or later with a hard-anodized aluminium bulkhead.

Like the 2nd Generation Ikelite model, this Fibre Optic Converter features heightened sensitivity for use with SEA&SEA or Nauticam housings with internal electrical-to-optical flash triggering devices. These devices translate the camera’s electrical signals into a series of LED flashes which are much less bright than a traditional built-in camera flash. The Fibre Optic Converter is also compatible with any system where the camera’s built-in flash can be seen by a fibre optic cord.

Attachment and Use

The Converter simply attaches to the strobe’s electrical bulkhead in place of a sync cord connector. The enlarged slave window provides an approximately 90-degree field of view for remote triggering.

The Fibre Optic Converter automatically configures itself for compatibility with both pre-flash and non-pre-flash camera modes. No setting of small switches or confusion over a number of pre-flashes. Simply turn on your strobe and take one picture to configure. This adapter is a manual exposure (non-TTL) trigger only. The strobe’s output may be adjusted using the manual power settings built into the strobe (varies by model).

An individual Fibre Optic Converter and a compatible cord is needed for each strobe. The use of two strobes requires two Fibre Optic Converters.

This converter attaches to an Ikelite DS strobe. It is not intended to be attached to a housing and will provide no functionality if attached to an Ikelite bulkhead in a housing.


There are two shooting scenarios where the High Sensitivity Optical Slave Converter # 4405 would be a better option:

  • If you’re shooting a DSLR or mirrorless camera with a Nauticam fibre optic converter and want to shoot at a higher frame rate (4 FPS or faster).
  • If your primary purpose is to trigger your strobes remotely at a distance from the housing without a fibre optic cable in between.
