Applicable Products
- SFP+ transceivers
- QNAP NAS equipped with SFP28 ports
Concept
SFP28 ports are backward compatible with SFP+ transceivers; however, the port can only support up to 10 Gbps network speed when connected to a SFP+ transceiver.
Small form-factor pluggable (SFP) network interface modules have distinct form factors, when an SFP+ transceiver is connected to an SFP28 port, the device automatically detects the inserted module's form factor and adjusts the network speed accordingly.
SFP28 ports are designed to support up to 25 Gbps, whereas SFP+ transceivers are designed to support data rates up to 10 Gbps.
QNAP recommends contacting the transceiver manufacturer prior to using SFP+ transceivers on SFP28 ports.
