## Summary description

BlueOptics XQ+CM0000-XS+ is a 100 Gigabit media converter that adapts a QSFP28 interface to an SFP28 port. It enables interoperability between 100GbE QSFP28 equipment and single 25GbE-compatible SFP28 transceivers or modules where supported. The converter is intended for use in data centers and carrier networks to facilitate hardware migration, link testing, or temporary interconnection without replacing existing switch or server optics.

## Long description

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.
Suitable for
 Data center migration from 100GbE QSFP28 to 25GbE SFP28 devices
 Temporary interconnection during hardware replacement or testing
 Link troubleshooting and diagnostics between QSFP28 and SFP28 ports
 Environments requiring mixed-port connectivity without replacing switches
Key specifications
 Supported speeds: 100 Gigabit host side with adaptation to single 25 Gigabit lane on SFP28 where supported
 Physical interfaces: QSFP28 (host) to SFP28 (client)
 Use case: media conversion between QSFP28 and SFP28 form factors
 Deployment environment: data centers, carrier networks, lab and test environments
 Form factor: compact inline converter suitable for rack and patch panel integration
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.
Usage 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.
