Verkkokehysmuunnin BlueOptics QSFP28–SFP28 BO-QSFP28-SFP28-BO (Multimode/Singlemode)

BlueOptics BO-QSFP28-SFP28-BO is a network media converter that adapts a QSFP28 interface to an SFP28 port, supporting both multimode and singlemode fiber. The adapter enables interoperability between devices with different transceiver form factors and helps integrate 25 Gb and 100 Gb optical links in environments where direct port compatibility is not available. The compact module is designed for insertion into QSFP28 cages, offering a practical way to connect servers, switches and uplinks that use SFP28 transceivers.

Advantages

This media converter supports conversion between QSFP28 and SFP28 form factors while accommodating multimode and singlemode fiber types. It permits reuse of existing SFP28 optics or cabling without requiring replacement of QSFP28-hosted equipment. The compact design reduces rack-space impact and simplifies mixed-port network deployments. By enabling cross-form-factor connectivity, it helps streamline network upgrades and maintain compatibility across different generations of optical equipment.

Key specifications

How to use

Insert the BlueOptics QSFP28-to-SFP28 adapter into an available QSFP28 port on the host device, ensuring correct orientation and secure seating. Plug the appropriate SFP28 transceiver into the adapter’s SFP28 slot and connect the fiber patch cable according to the transceiver’s multimode or singlemode specification. Verify link status and network configuration on both ends; the adapter provides passive form-factor conversion so link speed and protocol settings follow the installed optics and host device capabilities.

Recommendations

Use certified SFP28 transceivers that match the fiber type (multimode or singlemode) and maintain clean fiber connectors to ensure reliable optical performance. Check device documentation for any host-side compatibility notes and confirm that firmware and port settings on the host support the desired data rates. For critical links, validate signal integrity after installation and consider environmental conditions such as temperature and vibration as specified by the equipment vendors.
