General Description
OPTONE QSFP+ SR4 transceiver modules are designed for use in 40 Gigabit per second links over multimode fiber. They are
compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4.The optical transmitter portion of the transceiver
incorporates a 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) array, a 4-channel input buffer and laser driver, control
and bias blocks. The optical receiver portion of the transceiver incorporates a 4-channel PIN photodiode array, a 4-channel TIA
array, a 4 channel output buffer, control blocks.

Notes:
1. GND is the symbol for signal and supply (power) common for QSFP+ modules. 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.
2. VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently. Recommended host board power supply filtering is
shown below. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP+ transceiver module in any combination. The connector pins are each rated
for a maximum current of 500mA.
