The DSFP 56G PAM4 SMT Connector is part of the Amphenol DSFP range and is supplied in stock from our factory in Dongguan. DSFP doubles the lane count of a standard SFP footprint, giving two 56G PAM4 channels in the same panel space. It is a common choice where port density matters more than per-lane reach.
Where the DSFP 56G PAM4 SMT Connector fits
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
- Dual-lane SFP form factor
- 56G PAM4 signalling per lane
- Backwards-compatible footprint with SFP cages

Quality assurance
KINKUO operates an ISO 9001:2015 certified quality system. Production runs through in-process inspection at every station, covering continuity, dielectric strength, insulation resistance and visual criteria. Finished sfp series are verified against the drawing before packing, and a test report accompanies every shipment.
Board integration and thermal considerations
Amphenol high-speed connectors are specified by multi-source agreement, so the mechanical envelope is standard across vendors. What varies is the quality of the parts you receive and how well the thermal path is managed in your design.
- Confirm the cage and connector are a matched pair — mixing vendors across the two is a common source of fitment problems.
- Review thermal performance early in the design. Higher lane rates dissipate more power in the module, and the cage is part of the heat path.
- Check press-fit tooling requirements before committing to a volume build.
- Verify that signal-integrity data covers the lane rate you intend to run, not just the connector family name.
- Source through an authorised channel. At these lane rates a sub-spec part degrades link margin in ways that are expensive to diagnose.
Common questions
How do I verify that connectors are genuine?
Check marking quality, packaging and documentation. Genuine Amphenol product ships with consistent marking and traceable documentation. We supply through the authorised channel with full traceability.
Is there a minimum order quantity?
No. Amphenol connectors are supplied with no MOQ, which makes single-port replacement and validation builds practical as well as volume deployment.
Understanding the specification
The figures in the table above are not independent of one another. Read together they describe how this DSFP 56G PAM4 SMT Connector will behave in service, and where the practical limits sit once it is installed in equipment rather than tested on a bench.
- Series (Amphenol DSFP):
- Data rate (56G PAM4 per lane):
- Lanes (2):
- Mounting (SMT): Mounting style determines how mechanical load reaches the solder joints. Board-mounted parts should use board locks or locating posts so that cable pull is not carried by the solder.
- Compliance (MSA DSFP): Compliance covers the material declarations your quality system will ask for. The declarations are available for every part number we supply.
- Availability (In stock): Availability reflects current stock position. Held stock means a same-week dispatch; made-to-order means the lead time quoted applies from order confirmation.
Selecting an SFP-series connector
Amphenol high-speed connectors are specified by multi-source agreement, so the mechanical envelope is standard across vendors. What varies is the quality of the parts you receive and how well the thermal path is managed in your design.
Confirm the cage and connector are a matched pair. Mixing vendors across the two is a common source of fitment problems that only appear at volume, when tolerances stack in the wrong direction.
Review thermal performance early. Higher lane rates dissipate more power in the optical module, and the cage is part of the heat path — a thermal problem discovered after the board is laid out is expensive to correct.
Check press-fit tooling requirements before committing to a volume build, and verify that signal-integrity data covers the lane rate you intend to run rather than the connector family name alone. Source through an authorised channel: at these rates a sub-spec part degrades link margin in ways that are difficult to attribute.
Packaging, delivery and documentation
This item is in stock with a minimum order quantity of 1 pc and a stated lead time of ships within 24 hours. Orders ship on FOB, EXW, CIF or DDP terms as agreed at order confirmation, with real-time tracking provided once the shipment is booked.
Packaging is specified to survive international freight rather than to minimise volume. Connectors are supplied in anti-static packaging with pin protection where the contact geometry requires it; cable assemblies are coiled to a radius that respects the flex specification and secured so the assembly cannot move in transit. Both ends are labelled on multi-channel assemblies so a field replacement cannot be mis-wired.
Every shipment is accompanied by a test report covering continuity, dielectric strength, insulation resistance and any application-specific measurement performed. Where your quality system requires material declarations, batch traceability or joint sampling and sealing, confirm the requirement at the enquiry stage and we will build it into the order rather than adding it after production.
Further questions
Can I get a sample before committing to a production order?
Yes. Samples for engineering validation are dispatched within 24 hours for stocked items, and within the quoted production lead time for made-to-order assemblies. Every sample ships with its test report so that your validation is based on measured performance rather than on appearance.
What happens if the part does not fit the application?
Send us the mating half, a photograph or the equipment model and we will identify why. In most cases the answer is a different keying or coupling variant of the same family rather than a completely different product, and we would rather resolve it before you place a volume order than after.
Do you hold stock for repeat orders?
Stocked lines are held with safety quantity, and made-to-order tooling is retained so a repeat order does not repeat the tooling cost. For scheduled programmes we can agree a call-off arrangement that keeps material allocated against your forecast.
How these connectors are sourced and verified
These parts are supplied through Amphenol's authorised distribution channel, which means the product originates from Amphenol manufacturing and is neither remanufactured, re-marked nor sourced from rejected lots. Every part can be traced to its manufacturing batch, and documentation is available for incoming inspection and audit.
On receipt we verify marking quality, packaging integrity and part-number correspondence against the purchase order. Genuine product carries consistent marking and correct packaging; where either is absent the part is treated as unverified and is not released to a customer order.
Because these connectors are specified by multi-source agreement, the mechanical envelope is standard across vendors — but performance is not. At 112G and 224G per lane, differences in contact position tolerance, impedance control through the mating interface and cage shielding effectiveness decide whether a link holds margin. That is why we supply through the authorised channel rather than the open market, and why signal-integrity data is available on request for specific part numbers.
Where a customer is designing a new platform, our engineering team can support thermal and mechanical integration questions alongside the commercial supply. The support comes from the manufacturer rather than from a reseller's interpretation of a datasheet.
Warranty, returns and technical support
Amphenol connectors are supplied genuine through the authorised channel and carry the manufacturer's warranty, which grey-market product frequently does not. Where a verified defect is found within the applicable period, we will handle the replacement through the authorised process and provide the documentation your quality system requires.
Returns require a return authorisation before shipment, and goods should be retained in their original condition pending inspection. Stocked items returned unused in original packaging may be accepted within 30 days subject to a restocking assessment; assemblies built to a customer drawing are not returnable unless defective.
Technical support is provided by the same engineers who handle the specification, not by a separate call centre. If a DSFP 56G PAM4 SMT Connector behaves unexpectedly in service, send us the installation detail — cable length, routing, environment and the symptom pattern — and we will work through the likely causes with you. Enquiries are answered within two hours during business days, and on-site technical support can be arranged for programmes where that is more practical than remote diagnosis.
Ordering checklist
To quote accurately and avoid a second iteration, we need the part number or the original manufacturer reference, the quantity required for validation and for production, the required delivery date, and the destination country so that the correct Incoterm can be applied. Where the item is a replacement for an obsolete part, a photograph of the existing connector and the equipment model will usually let us confirm the equivalent without a sample.
If your quality system requires material declarations, batch traceability, joint sampling and sealing, or a first-article inspection report, state that at the enquiry stage. These can all be accommodated, but retrofitting them into a production schedule costs more time than building them in from the start.
Technical documents
The original drawings and datasheets for this part are available to download. They are the documents issued by the manufacturer and are the reference to quote against when confirming a specification or a cross-reference.

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 sfp series to customers across South China, East China, Japan, Europe and North America.
