QSFP28 parallel optic module

QSFP28 MSA transceiver modules

The QSFP28 (quad small form-factor pluggable) is a hot-pluggable, high-density transceiver. It is a full-duplex optical module that offers 4 independent transmit and receive channels, each capable of 25 Gb/s operation for an aggregate data rate of 100 Gb/s. 
QSFP28 supports 100G Ethernet, data center, cloud networks, and high-performance computing networks applications. 
QSFP28 modules are available in multimode and single mode versions and also as AOC (active optical cable).
