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). QSFP28 is designed to meet harsh operating conditions including temperature, humidity, and EMI interference.
