100g QSFP28 to 4 pcs 25G QSFP AOC cable
1.Description
This product 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, 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.

4. Functional Description
The QSFP28 module converts the parallel electrical input signals into parallel optical signals by a driven Vertical Cavity Surface Emitting Laser (VCSEL) array inside the QSFP28 module on its transmitter side. The optical signals propagate first through 4 optical data transmission lanes in the multimode ribbon fibers and then through those of the 4 separate dual-core fiber cables. They are then captured by the photo diodes inside the receivers of the 4 SFP28 modules at the other end. The optical signals are converted into electrical signals, which are outputted by the receivers of the 4 SFP28 modules individually.
In the reverse direction, each of the 4 SFP28 modules converts the electrical input signal into an optical signal by a driven VCSEL inside the module on its transmitter side. The 4 optical signals propagate first through the other transmission lanes of the 4 separate dual-core fiber cables and then through those in the multimode ribbon fibers. They are captured by the photo diode array inside the QSFP28 on its receiver side. The optical signals are converted into parallel electrical signals and outputted. Consequently, the QSFP28 terminal of the cable has 8 ports, 4 for data transmission and 4 for data receiving, to provide a total of 100Gb/s data exchange rate while each of the 4 SFP28 terminals at the other end has 2 ports, 1 for data transmission and 1 for receiving, to provide 25Gb/s data exchange rate.
