Kabel-adapter NVIDIA QSFP28 naar SFP28 adapter 980-9I78I-00A000, zwart metallic

NVIDIA 980-9I78I-00A000 is a cable gender changer that adapts a QSFP28 connection to an SFP28 interface. The adapter features a black metallic finish and is designed to provide a straightforward mechanical and electrical conversion between QSFP28 and SFP28 transceiver form factors, allowing continued use of compatible high-speed modules and links without changing cabling or host ports.

Advantages

The adapter delivers a compact mechanical solution to connect devices with mismatched QSFP28 and SFP28 ports while preserving signal integrity for supported link speeds. Its metal housing offers robust physical protection and improved shielding against electromagnetic interference. The design minimizes the need for additional adapters or rewiring when integrating different transceiver types in racks and networking equipment.

Suitable for

• Adapting a QSFP28 port to accept SFP28 transceivers in data center switches and routers
• Temporary or permanent port conversions during maintenance or equipment upgrades
• Laboratory and test environments where multiple transceiver types are evaluated
• Mixed-vendor setups requiring physical form-factor compatibility without changing transceivers

Key specifications

• Interface conversion: QSFP28 (host side) to SFP28 (module side)
• Supported data rates: suitable for high-speed Ethernet lanes including 25 Gbps-class links
• Construction: metallic housing with black finish for mechanical durability and EMI shielding
• Form factor: compact inline gender changer designed for hot-pluggable transceivers
• Compatibility: intended for use with compliant QSFP28 and SFP28 transceivers and ports

How to use

Install the adapter by inserting the SFP28 transceiver into the SFP28 end and then connecting the QSFP28 side into the host QSFP28 port, ensuring proper alignment and secure seating. Perform link negotiation and verify link status through the host device management interface. Remove the adapter by reversing the process, taking standard electrostatic discharge (ESD) precautions and ensuring the port is inactive if required by the equipment vendor.

Recommendations

Use the adapter only with transceivers and equipment that explicitly support this type of form-factor conversion. Verify supported link speeds and module compatibility in device documentation before deployment. Keep the adapter and transceiver optical/electrical interfaces clean, and follow ESD and hot-plugging guidelines to avoid damage.
