400G SR4 transceivers are optical modules designed to support 400 gigabits per second (Gbps) data rates over short distances. 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 article explains the engineering differences, the physical cabling and connector implications, performance characteristics, and real-world use cases so you can pick the right part for. As the new benchmark for multimode transmission, this module leverages a 4×100G PAM4 parallel architecture and OSFP packaging advantages to deliver 400Gbps.

40GE QSFP+ SR4 Optical Transceiver (IT)

The ModSelL allows the use of multiple QSFP modules on a single 2-wire interface bus. When the ModSelL is "High", the module will not respond to any 2-wire interface communication from the host.
