If two 256-QAM channels with 38 Mbps throughput are bonded, what is the total downstream throughput?

If two 256-QAM channels with 38 Mbps throughput are bonded, what is the total downstream throughput?

• A. 38 Mbps
• B. 76 Mbps
• C. 128 Mbps
• D. 54 Mbps

Answer: (B)

When two channels are bonded, their individual throughputs are added together to determine the total throughput. In this scenario, you have two separate 256-QAM channels, each capable of delivering 38 Mbps. To calculate the total downstream throughput when bonding these two channels, simply take the throughput of one channel (38 Mbps) and double it, since there are two channels: 38 Mbps + 38 Mbps = 76 Mbps. Therefore, the total downstream throughput achieved by bonding the two 256-QAM channels is 76 Mbps. This demonstrates the principle that bonding channels enhances bandwidth, allowing for greater data transfer rates.
