Optical Splitter Cables technical selection Q&A

These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.

The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.

What does this AOC splitter connect?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

It connects one OSFP electrical interface to two QSFP56 interfaces, providing two 200G branches. Its internal multimode fibers and optical engines are a fixed assembly.

Which adapter family is explicitly covered?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

The product manual says both Ethernet and InfiniBand applications are supported only with ConnectX-6 cards. Verify the exact card and switch configuration.

Are the flat and finned versions interchangeable?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

Use the exact flat-to-flat OPN selected for the endpoint cooling design. The official family photo shows a finned head and does not prove the appearance of the -FLT version.

How is its power budget split?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

Allow up to 10 W at the OSFP head and up to 5 W at each QSFP56 end. The length-specific OPN must still match the planned cable route.

Where does forward error correction take place?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

The FAQ places FEC in the switch and network adapter. Match the supported endpoint configuration; a cable does not independently fix a FEC mismatch.

Why can a cable have two minimum bend radii?

Applicable catalog candidates: 980-9I110-00H005, 980-9I114-00H015, 980-9I116-00H020, 980-9I118-00H030.

The connector exit generally needs a larger bend radius than the cable body. Follow the exact assembly drawing and leave adequate space behind the rack door.
