The main difference between QSFP-SR4-40G and QSFP-4×10G-SR lies in their support for 4×10G breakout applications. Per the 10G-SR protocol standard, the maximum receiver input optical power is -1dBm. The QSFP-SR4-40G has a transmit power range of -7.6 to +2.4dBm, with measured output >0dBm, which exceeds the 10G SR receiver limit and may trigger alarms, making it unsuitable for breakout applications. In contrast, the specially designed QSFP-4×10G-SR strictly controls its transmit power within -7.6 to -1dBm, with measured output <-1dBm, staying below the 10G SR receiver limit without causing alarms, thus being fully suitable for breakout applications.
