SNAP12 is a 12-channel pluggable parallel optical transmitter or receiver module with an MSA standard chassis mountable MPO interface. Unlike the regular pluggable SFP/SFP+, This form factor features 12-channel parallel optics to achieve 40G/100G data speed. The earliest SNAP12 dates back to around 2002, when the SNAP12. The SNAP12 Transmitter and Receiver modules enable high performance multi-channel optical links designed for very short reach (VSR) high-speed data communication and computing applications where bandwidth bottlenecks are incumbent. It features low electromagnetic radiation and strong.
