● Transmission data rate up to 10.3125Gbit/s per channel
● SFF-8436 QSFP+ compliant
● Hot pluggable electrical interface
● Differential AC-coupled high speed data interface
● 4 channels 850nm VCSEL array
● 4 channels PIN photo detector array
● Maximum link length of 300m on OM3 Multimode Fiber (MMF)and 400m on OM4 MMF
● Low power consumption <1.5W
● Case operating temperature
     Commercial: 0 ~ +70℃
     Industrial: -40 ~ +85℃
● 3.3V power supply voltage
● RoHS 6 compliant

Applications
