Product Information
The Sea & Sea Fiber-Optic Cable II S/2 Connectors is a 310mm (12.2 inch) fiber-optic sync cable that carries the light signal from a camera's built-in flash to a Sea & Sea strobe. It is built from 613 fibers (cores) inside a single cable, so attenuation of light stays minimal even when the cable is bent, and it is more resistant to distortion, bending and physical impact than single-fiber cables.
Who it is for
This cable is for underwater photographers running an optically triggered strobe setup, where the housed camera's internal flash fires the external strobe instead of an electrical sync cord. The short 310mm length suits compact rigs and tight strobe arm positioning, where a long cable would loop and snag. It is also a sensible spare to carry on a dive trip, since a damaged or kinked sync cable can take an entire strobe out of service.
Key details
- Multi-core construction: 613 fibers (cores) within a single fiber bundle.
- Material: methacrylic resin.
- Fiber diameter: 1.5mm / 0.059 inch.
- Cable diameter: 2.7mm / 0.105 inch.
- Total length: 310mm / 12.2 inches.
- Product number: 50135.
Compatibility and sizing
The Fiber-Optic Cable II S/2 uses S/2 connectors and is intended for underwater camera and strobe systems that synchronize a camera's built-in flash with a Sea & Sea strobe. Because the cable transmits the flash signal optically rather than electrically, the camera's internal flash must be able to fire through the housing's fiber-optic port. If you are unsure whether your housing port and strobe accept the S/2 connector, confirm the fitting before ordering.

Frequently Asked Questions
How long is the Sea & Sea Fiber-Optic Cable II S/2?
The total length is 310mm, or 12.2 inches. That short run is intended for compact strobe setups where the strobe sits close to the housing's fiber-optic port, so there is little excess cable to loop or snag on arms and clamps. The cable itself measures 2.7mm / 0.105 inch in diameter with a 1.5mm / 0.059 inch fiber inside.
What makes the Fiber-Optic Cable II different from a single-fiber cable?
The Fiber-Optic Cable II is composed of 613 fibers (cores) within a single fiber rather than one solid core. Light attenuation stays minimal even when the cable is bent, so the flash signal reaches the strobe without loss. Sea & Sea also states that this multi-core construction is more resistant to distortion, bending and physical impact than single-fiber cables.
What is this cable made of, and does it carry electricity?
The cable is made of methacrylic resin, a plastic optical fiber material. It is a fiber-optic sync cable, which means it carries the light pulse from the camera's built-in flash to the strobe rather than an electrical signal.
What is the Sea & Sea part number for this cable?
Sea & Sea lists this item as product number 50135, and the DiveCatalog SKU is SS-50135 with barcode 702730810620. Use the 50135 product number when matching a replacement to an existing Sea & Sea optical strobe setup, and confirm that your housing port and strobe accept the S/2 connector style before ordering.
