Converter M.2 Key M to 1 x OCuLink SFF-8611 with 45 cm cable — DELOCK 64360

The DELOCK converter adapts an M.2 Key M slot to a single OCuLink SFF-8611 connector and includes an integrated 45 cm cable. It provides physical and electrical conversion between an M.2 Key M interface and an OCuLink SFF-8611 device, enabling connection of compatible NVMe or storage host adapters where an external OCuLink connection is required. The compact adapter facilitates integration into systems that need an external OCuLink port while using an internal M.2 Key M slot.

Advantages

The adapter offers a simple and space-saving solution for converting an M.2 Key M interface to an OCuLink SFF-8611 connector without modifying the host board. The included 45 cm cable gives flexibility in routing and placement inside a chassis or between enclosures. Electrical compatibility for NVMe/storage signals is maintained to support proper communication between host and device. The small form factor and pre-attached cable reduce installation time and minimize additional cabling needs.

Suitable for

• Connecting NVMe or storage devices that use an OCuLink SFF-8611 interface to a system with an M.2 Key M slot
• Systems requiring an external OCuLink port provided from an internal M.2 connector
• Test benches and development setups where flexible cable routing is needed
• Upgrading or adapting servers, workstations, or embedded systems to support OCuLink storage devices

Key specifications

• Interface conversion: M.2 Key M to OCuLink SFF-8611
• Cable: integrated 45 cm cable for connector placement flexibility
• Supported signal type: NVMe/storage host signaling over PCIe lanes
• Form factor: compact adapter suitable for internal mounting and cable routing

How to use

Install the adapter by inserting the M.2 end into an available M.2 Key M slot on the host board, ensuring correct orientation and seating. Route the attached 45 cm cable to the desired external or internal location and connect the OCuLink SFF-8611 plug to the compatible device or enclosure. Re-seat any retention screws or brackets as required by the host system and secure cable routing to avoid strain on the connectors. Power on the system and verify device recognition in the host firmware or operating system.

Recommendations

Ensure the host system supports the required NVMe or PCIe lane configuration exposed through the M.2 Key M slot before installation. Handle connectors gently and avoid bending the cable sharply near the terminations. Use appropriate ESD precautions when installing the adapter and verify firmware or driver support for OCuLink-connected devices in the target environment.
