GND is the symbol for signal and supply (power) common for the QSFP+module. All are common within the QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal-common ground plane. IV. QSFP+ Recommended Host Board Power Supply Filtering image.png V.

The module signal grounds, VeeR and VeeT, shall be isolated from the module case. 2. This is an open collector/drain output and shall be pulled up with 4.7-10k to Vcc_Host on the host board. Pull ups can be connected to multiple power supplies, however the host board design shall ensure that no module has voltage exceeding module VccT/R + 0.5 V. 3. This is an open collector/drain input and shall be pulled up with 4.7-10k to VccT in the module. 4. See 2-wire electrical specifications. 5. This shall be pulled up with 4.7-10k to Vcc_Host on the host board. VII. SFP+ Recommended Interface Circuit image.png VIII. SFP+ Recommended Host Board Power Supply Circuit image.png IX.
