## Summary description

BlueOptics EB49-BO is a QSFP28 to SFP28 converter module that enables use of an SFP28 transceiver in a 100 Gigabit QSFP28 port. The adapter supports both multimode and singlemode SFP28 transceivers and operates in the temperature range 0°C to +70°C. It is intended for network equipment compatibility, lab testing, and incremental port upgrades where QSFP28 ports must accept SFP28 modules.

## Long description

BlueOptics EB49-BO is a QSFP28 to SFP28 converter module designed to allow insertion of an SFP28 transceiver into a 100 Gigabit QSFP28 port. The adapter accepts both multimode and singlemode SFP28 transceivers and provides a solution for compatibility between different form factors without requiring changes to the host equipment. It is specified for operation in ambient temperatures from 0°C to +70°C and is intended for use in networking environments where flexible port provisioning and lab interoperability are needed.
Advantages
The converter module permits use of existing SFP28 optics in QSFP28 ports, enabling incremental migration and mixed-form-factor deployments. It supports both multimode and singlemode SFP28 transceivers, simplifying inventory and reducing the need for separate QSFP28 optics. The module is compact and passive, requiring no additional power or configuration, and is specified for standard operating temperatures suitable for common data center and lab conditions.
Suitable for
Port migration from 25G/10G SFP28 optics to 100G QSFP28 ports
Laboratory testing and interoperability checks with SFP28 transceivers
Incremental network upgrades where QSFP28 ports must accept SFP28 modules
Environments using both multimode and singlemode fiber transceivers
Key specifications
Form factor conversion: QSFP28 host interface to SFP28 transceiver slot
Supported transceiver types: multimode and singlemode SFP28
Operating temperature range: 0°C to +70°C
Intended data rate class: compatible with 100 Gigabit QSFP28 ports accepting SFP28 optics
Passive adapter design with no external power or software configuration required
How to use
Install the converter by inserting the module into the QSFP28 port on the host device until it seats securely, then insert the SFP28 transceiver into the converter’s SFP28 slot. Ensure the transceiver type (multimode or singlemode) matches the connected fiber and link equipment. Confirm that the host system supports converter usage and accepts the SFP28 transceiver; some equipment may require port or firmware support for form-factor adapters. Perform link tests and monitor port status after installation to validate connectivity.
Usage recommendations
Use the adapter in environments within the specified temperature range and handle SFP28 transceivers and fiber connectors according to standard ESD and cleanliness procedures. Verify compatibility with the host device and transceiver optics before deployment, and use appropriate fiber patching and testing tools to confirm link quality after installation.
