Full duplex
The SAP-48GBP supports the following types of transceiver modules:
•
100 Mbps SFP transceiver modules
•
1000 Mbps SFP transceiver modules
•
100/1000 Mbps SFP transceiver modules
•
10/100/1000 Mbps SFP copper transceiver modules supporting fiber-to-copper conversion (The
SAP-48GBP supports 10/100/1000 Mbps auto-sensing if used together with a transceiver
module.)
The SAP-48GBP is optional to be separately ordered if needed.
Use transceiver modules provided by H3C only. The device might be incompatible with other transceiver
modules and thus displays alarms automatically.
Interface cables
•
When working with SFP transceiver modules, the SAP-48GBP must use an optical fiber with LC-type
connectors.
