The QSFP-100G-SM-SR transceiver from Cisco is designed to provide 100Gbps Ethernet connectivity over single-mode fiber. It uses the 100GBase-CWDM4 standard, which involves transmitting data over four separate wavelength channels on a single fiber.

To achieve the maximum bandwidth of this transceiver, there are several factors to consider:

• Fiber Type: The transceiver is designed for use with single-mode fiber, which has a smaller core diameter than multimode fiber and provides a longer maximum distance. Single-mode fiber also provides higher bandwidth and lower attenuation compared to multimode fiber.
• Fiber Quality: The quality of the fiber plays a critical role in achieving the maximum bandwidth. The fiber should be free of any defects or bends that could cause signal loss, and the connectors must be properly terminated to ensure low insertion loss.
• Wavelengths: The 100GBase-CWDM4 standard uses four different wavelengths to transmit data over the fiber. The transceiver must be able to transmit and receive these wavelengths with high accuracy to ensure maximum bandwidth.
• Distance: The maximum distance over which the transceiver can provide 100Gbps connectivity depends on several factors, including fiber quality, fiber type, and the amount of optical loss in the system. The QSFP-100G-SM-SR is designed for use over distances of up to 400 meters.
• Interference: The 100Gbps data rate of the transceiver is sensitive to any interference from other optical signals. The use of optical filters or the careful placement of transceivers can help reduce the impact of interference on the maximum bandwidth.
