BlueOptics QSFP28 to SFP28 Converter 845969-001 for 100 Gigabit links

The BlueOptics QSFP28 to SFP28 Converter 845969-001 enables connectivity between QSFP28 ports and single-lane SFP28 transceivers for 100 Gigabit Ethernet links. Designed for environments where QSFP28 interfaces are present but SFP28 modules are required, this converter adapts a QSFP28 socket to accept an SFP28 transceiver while maintaining standard 100G signaling and link integrity. It is intended for use in data centers and network upgrade projects to simplify transition and interoperability without replacing existing QSFP28 hardware.

Advantages

The converter provides a compact, passive solution to bridge QSFP28 ports and SFP28 optics, reducing the need for additional switches or adapters. It supports hot-pluggable operation and preserves link performance by aligning electrical and mechanical interfaces between QSFP28 and SFP28 form factors. Its straightforward design minimizes installation time and allows reuse of existing SFP28 transceivers in QSFP28-equipped devices.

Suitable for

• Data center link adaptation between QSFP28 ports and SFP28 transceivers
• Network upgrades where mixed transceiver types must be supported
• Short-term migration or lab testing of 100 Gigabit optics
• Situations where replacing QSFP28 hardware is impractical

Key specifications

• Supported link rate: 100 Gigabit Ethernet compatibility
• Form factor adaptation: QSFP28 host interface to SFP28 transceiver slot
• Optical/electrical signaling: compatible with standard 100G single-lane SFP28 transceivers
• Hot-pluggable: supports insertion/removal without system shutdown
• Physical dimensions: compact adapter size suitable for dense rack environments

How to use

Insert an SFP28 transceiver into the converter’s SFP28 slot until it latches, then plug the converter into the QSFP28 port on the switch or server. Verify link status through the host device management interface and ensure transceiver type and cable type match network requirements. Remove the converter by unlatching the SFP28 transceiver and gently extracting the assembly from the QSFP28 port when maintenance or reconfiguration is needed.

Recommendations

Use certified SFP28 transceivers that match the intended fiber or copper cabling and comply with 100G specifications. Confirm host device compatibility with passive QSFP28-to-SFP28 adapters and monitor link parameters after installation. Avoid excessive mechanical force when inserting or removing the converter to prevent damage to the transceiver or QSFP28 port.
