100G QSFP28 to 4X25G SFP28 +AOC t is a high data rate parallel active optical cable (AOC), to overcome the bandwidth limitation of traditional copper cable. The AOC is terminated with a QSFP28 module at one end and four SFP28 modules at the other. With the QSFP28 terminal, it offers 4 independent data transmission channels and 4 data receiving channels via multimode ribbon fibers, each capable of 25Gb/s operation. The fiber ribbon then fans out to four fiber cables, each of which is terminated with an SFP28 module. Consequently, an aggregate data rate of 100Gb/s over up to 100m transmission can be achieved by this product, to support the ultra-fast computing data exchange. The product is designed with form factor, and optical/electrical connection according to the QSFP28 and SFP28 Multi-Source Agreements (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
