400G SR4 transceivers are optical modules designed to support 400 gigabits per second (Gbps) data rates over short distances. The “SR” stands for “Short Reach,” and the “4” denotes that the transceiver uses four optical channels, each capable of transmitting 100 Gbps. First, let's clarify what VR, SR, DR, FR, LR, ER, and ZR stand for, so that we can understand and identify them: VR (Very Short Range): Transmission distance usually 0~100 meters, using multimode fiber for short data center connections. This transceiver supports 400G transmission over multimode fiber (MMF). Quick summary: SR4 modules are short-reach, multimode solutions that use MPO/MTP ribbon connections and are optimized for cost-effective, dense data-center fabrics over OM3/OM4 MMF; DR4 modules are data-center reach, single-mode solutions (or single-mode MPO variants) that extend reach. QSFP 40G SR4 is a short-reach 40Gbps optical transceiver designed for high-density data center interconnects using multimode fiber and parallel optics. Their primary application is within data.

Optical modules have a series of components inside, some of which have received attention from standards development organizations. In many cases, the baud rate of the optical interface does not equal the baud rate of the electrical interface. In these cases, a gearbox is used within the module to convert between the two rates. For example if the module supports 4 x 25 Gb/s electrical inputs and 2 wavelengths of 50 Gb/s optical inte.
