The 100G QSFP28 SR4 optical module has a wavelength of 850 nm and uses a 4-channel 850 nm VCSEL laser array and a PIN photodetector array, and each channel can run at a rate of 25Gbps. The 100G QSFP28 SR4 optical module uses an MPO interface (12 cores) and has a transmission distance of 70m when used with OM3 multimode fiber and 100m when used with OM4 Multimode fiber.

The 100G QSFP28 SR4 optical module is not only compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4 Ethernet standards, but is also compatible with the IEEE 802.3ba 40GBASE-SR4 Ethernet and InfiniBand FDR/EDR standards.

The 100G QSFP28 SR4 optical module is suitable for short-distance connections in data centers and enterprise networks, and it can realize interconnection between 100G QSFP28 ports, also can use MPO-4xLC fiber optic patch cords to interconnect 25G SFP28 ports and 100G QSFP28 ports.
