ikelite updates fiber optic converter

Ikelite has announced that, starting September 2018, all their bulkheads and sync cord plugs will be constructed of hard anodized aluminum. In line with this, the company has announced the third generation of their fiber optic converter for DS strobes. In common with the preceding version, this converts the electrical bulkhead of any Ikelite DS strobe into a fiber optic port and is extra sensitive for use with internal LED triggers

The new converters are shipping now, priced at $125 in the U.S.A.

Press Release

Fiber Optic Converter for DS Strobes (3rd Gen)

Product # 4401.3 $ 125.00


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


This 3rd Generation of the Fiber Optic Converter features a hard anodized aluminum plug connection which reduces weight without sacrificing durability. It is recommended for use with any Ikelite strobe produced September 2018 or later with a hard anodized aluminum bulkhead. Read more about the material change here.

Like the 2nd Generation model, this Fiber 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 Fiber Optic Converter is also compatible with any system where the camera’s built-in flash can be seen by a fiber 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 approximately 90 degrees field of view for remote triggering.

The Fiber 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 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 Fiber Optic Converter and compatible cord is needed for each strobe. Use of two strobes requires two Fiber 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:
