- GND is the symbol for signal and supply (power) common for the QSFP28 module. All are common within the QSFP28 module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal-common ground plane. 2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently. Recommended host board power supply filtering is shown in Recommended Interface Circuit. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP28 module in any combination. The connector pins are each rated for a maximum current of 1000 mA. belfuse.com/cinch

All versions of this laser are Class 1 laser products per IEC/EN 60825-1. Users should observe safety precautions such as those recommended by ANSI Z136.1, ANSI Z36.2 and IEC 60825-1. This product conforms to FDA (CDRH) 21 CFR 1040.10 and 1040.11 except for deviations of laser safety class designation pursuant to ‘Laser Notice No.50’ Product labeling: Class 1 Laser Product Compliance with 21 CFR 1040.10 and 1040.11 If labeling is not affixed to the module due to size constraints; then rather, labeling is placed on the outside of the shipping box. This pr oduct is not shipped with a power supply. Caution: use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
