The SFF-8612 Oculink 42Pin R/A DIP Connector is part of the Oculink range and is supplied in stock from our factory in Dongguan. Genuine product carries consistent marking and correct packaging; at high lane rates a sub-spec copy degrades link margin in ways that are difficult to attribute.
Specifying the SFF-8612 Oculink 42Pin R/A DIP Connector
Every unit is inspected before dispatch and ships with a test report, so incoming inspection becomes a document check rather than a re-test. Material compliance is documented against RoHS and REACH.
Key features
- Genuine Amphenol product through the authorised distribution channel
- Full batch traceability with documentation for incoming inspection
- No minimum order quantity — single pieces and volume builds both supported
- Signal-integrity data available for the lane rate you intend to run
- Cage and connector available as a matched pair
- Engineering support from the manufacturer rather than a reseller interpretation
Technical specifications

Quality assurance
Product is sourced through Amphenol's authorised channel and verified on receipt for marking quality, packaging integrity and part-number correspondence. KINKUO operates an ISO 9001:2015 certified quality management system, and documentation is available for every batch supplied.
Selecting the right Oculink
Verify that signal-integrity data covers the lane rate you intend to run, not simply the connector family name. Characterisation at the previous generation does not guarantee margin at the next one.
Check press-fit tooling and board keep-out requirements before releasing the board. At these densities the mechanical envelope is tight, and a routing change after release is costly.
Packaging and delivery
Parts are supplied with the documentation your incoming inspection needs: part-number correspondence, batch traceability and, where applicable, signal-integrity data for the lane rate in question.
Because there is no minimum order quantity, a single port can be replaced as easily as a volume build can be scheduled. That matters most during validation, when a design change may require a different variant at short notice.
Common questions
Do you provide signal-integrity data?
Where it is available from the manufacturer for the specific part and lane rate, yes. Tell us the protocol and generation you are designing to.
Which lane rates do you cover?
From 25G through 224G per lane, across SFP, QSFP, QSFP-DD, OSFP and OSFP-XD, CFP2/CFP4, CDFP, MCIO, SlimSAS and related families.
Do you support thermal design questions?
Our engineering team can discuss cage selection and airflow considerations alongside the commercial supply, drawing on the manufacturer's data.

Why source this part from KINKUO
We manufacture rather than resell, which means the part you receive is built on our own calibrated equipment by the same team that engineers it. That removes the margin stacking of a trading chain and keeps lead times predictable. Established in 2010, we supply oculink to customers across South China, East China, Japan, Europe and North America.

Every dip connector we ship is inspected against the drawing before packing. A dip connector can be supplied with a batch test report and material declarations. Where a dip connector runs in volume, call-off scheduling keeps material allocated.
