Conversor de suporte QSFP28 para SFP28 BlueOptics XQ+CM0000-XS+ – 100 Gigabit

BlueOptics XQ+CM0000-XS+ is a 100 Gigabit media converter that adapts a QSFP28 interface to an SFP28 port. The device enables interoperability between 100GbE QSFP28 equipment and SFP28 transceivers or modules that support 25GbE lanes, allowing migration paths and temporary interconnections in data center and carrier environments. It is designed for inline use to map a QSFP28 electrical or optical channel to a single SFP28 port without requiring replacement of existing switch or server optics.

Advantages

The converter provides a compact and passive method to link QSFP28 ports to SFP28 ports where lane breakout or lane compatibility is supported by the host devices. It reduces the need to purchase new optics or switches during phased upgrades, simplifies link testing and troubleshooting by enabling direct connection between different form factors, and supports high-density deployment scenarios common in modern data centers. The unit is compatible with standard QSFP28 and SFP28 physical interfaces and is intended for straightforward integration into existing racks and patch panels.

Key specifications

How to use

Insert the QSFP28 end of the converter into the host QSFP28 port and the SFP28 transceiver or cable into the SFP28 side. Verify that both connected devices support the required lane breakout or lane compatibility (25GbE on a single SFP28 lane) and that link negotiation settings on the switches or servers match the intended speed and duplex. Use standard procedures to secure modules in place and observe link status LEDs on the connected equipment to confirm successful operation. For diagnostic sessions, connect test equipment to the SFP28 side and monitor link performance from the host side as needed.

Recommendations

Confirm host device support for QSFP28-to-SFP28 adaptation before deployment, ensure compatible transceivers or direct-attach cables are used on the SFP28 side, and follow manufacturer guidelines for hot-plugging optics to prevent link disruption or hardware stress.
