Board-side 400G interface
WHSFP51311D002 sits where the module card edge plugs in. Plan the 400G breakout from its contacts early, with short stubs and few vias.

QSFP112 PCB Connector
Review WHSFP51311D002, the PCB connector listed for the QSFP112 family. Check the target module interface, contact layout and PCB drawing before design-in. This is a connector, not a cage assembly or optical transceiver; request the required mating and mechanical documentation alongside samples or pricing.

Series overview
QSFP112 connector for 400G host boards
A QSFP112 connector is the PCB connector of a 400G pluggable port: it takes the module’s card edge on the host board, while a QSFP cage at the panel holds the module. It is also called a QSFP112 PCB connector. WHSFP51311D002 is listed as a 1 x 1 part with 15U gold and a 400G rating. See also QSFP-DD connectors and cages and QSFP56 connectors.
Port LEDs come from the cage
The selector shows no light pipe on WHSFP51311D002, so port LEDs and any light pipe come from the transceiver cage and panel design.
Cooling sits in the cage
At 400G, cooling is planned at the QSFP cage, for example with a heat sink. Choose cage, heat sink and connector position together.
Footprint from the datasheet
No separate PCB footprint file is listed, so build the QSFP112 connector footprint from the datasheet drawing and check it before release.
Applications
Where a QSFP112 connector fits
QSFP112 ports carry 400G links in data center, AI and test hardware.
400G switches and routers
Leaf, spine and edge platforms can place WHSFP51311D002 under each 400G port, with cage and heat sink chosen for the faceplate and airflow.
Network cards and accelerators
Accelerator nodes and 400G network cards use single ports at the bracket, where a 1 x 1 connector keeps the board-side layout compact.
Test and measurement
400G traffic generators and lab fixtures see frequent module swaps, so check contact plating and cage latch details first.

FAQ & related guides
Questions on the QSFP112 connector
Answers on manufacturing, plating and the QSFP-DD format.
Which QSFP112 part is listed?
The inspected English catalog lists WHSFP51311D002 as a connector. Submit any different configuration for review rather than assuming it is an available SKU.
Does this part include a cage?
It is listed as a connector. Confirm the cage separately and check the specified mating arrangement and mechanical drawings.
Can I reuse a QSFP-DD PCB footprint?
Do not assume footprint compatibility. Compare the selected part’s contact and retention pattern, mechanical datums and electrical requirements with the existing design.
Does the catalog rate guarantee the host data rate?
No. Validate connector, module and PCB requirements as a complete interface. The catalog field is a candidate-selection aid, not a system test result.
How do I request documents, samples or a quote?
Send WHSFP51311D002, quantity, project stage, destination and timing. Include target-module and PCB constraints if mating or replacement review is required.
Is VOOHU a QSFP112 connector manufacturer?
Yes. VOOHU manufactures WHSFP51311D002 in its own connector factory in Dongguan, China. The same plant builds our QSFP-DD and QSFP56 parts, so 200G and 400G host connectors can share a source.
What plating does the QSFP112 connector use?
WHSFP51311D002 lists 15U gold on its contacts. For ports with frequent module swaps, check the plating and durability data in the datasheet.
How does QSFP112 compare with QSFP-DD for 400G?
Both appear in our range with a 400G rating. QSFP112 keeps the QSFP outline, while QSFP-DD is the double-density format on our QSFP-DD connector page. Select by the module your system uses, and lay out each part to its own drawing.
