PCIe Gen4 gender changer with NB8NQ504M

This PCIe Gen4 gender changer converts an OCuLink 4i (SFF-8612) connection to a PCIe x4 interface. It integrates a PCIe ReDriver and clock buffer to maintain 16 GT/s signal integrity over extended trace lengths and cables. The adapter targets server and high-performance computing installations that require reliable PCIe 4.0 extension. Built-in buffers for PERST#, WAKE#, CLKREQ# and PWRBRK# support robust link management across longer runs.

Verify host connector

Confirm the host side presents an OCuLink 4i (SFF-8612) port with pin-out defined by SFF-9402 Rev 1.1. Ensure the system firmware is UEFI 2.3.1 or later and the operating environment is Windows 7, 8, 8.1 or 10. Check that the target device conforms to the PCI Express Base Specification Rev 4.0 and the PCI_Express_OCuLink_1.0a standard. Validate physical clearance for the adapter and any attached cable in the chassis.

Fits rack, microserver and tower server builds

The adapter plugs into an OCuLink 4i port and presents a PCIe x4 Gen4 link for add-in cards such as hardware accelerators or storage controllers. On-board 3.3 V SMCLK/SMDAT, 100 MHz clock and side-band signal buffers free the builder from strict trace-length limits. A green D3 LED indicates when the host bus adapter is ready. The assembly is designed and made in Taiwan.

Questions about this item

What connectors and components come with the Innocard PCIe Gen4 gender changer?

The adapter includes a built-in OCuLink 4i (SFF-8612) connector and a PCIe x4 Gen4 interface with an integrated NB8NQ504M ReDriver, clock buffer and side-band signal buffers. No cables or mounting brackets are mentioned.

Which version of the SFF-8612 and PCIe specifications does this model implement?

It complies with SFF-8612 Specification Version 3.5, PCI Express Base Specification Rev 4.0 and PCI_Express_OCuLink_1.0 a, using pin-out defined by SFF-9402 Rev 1.1.

What does the 16 GT/s differential pair rating mean for real-world SSD or accelerator performance?

The on-board ReDriver and 100 MHz clock buffer extend clean 16 GT/s Gen4 signalling over longer traces and cables, reducing signal degradation for SSDs, GPUs or hardware accelerators in rack, tower or microserver chassis.
