Introduction of 100G multi-mode optical modules—SR4/SRBD/SWDM4
With the rapid development of 5G, AI, big data, cloud computing and other services, the data center network is required to develop in the direction of high speed, high density, and efficient operation and maintenance. At present, 100G is widely used in China. This article introduces three mainstream solutions for 100G multimode optical modules. 1) 100G QSFP28 SR4 Interface type: multi-mode MPO-12F working principle: The center wavelength of 100GBASE-SR4 is 850nm, which can provide four independent transmission and reception channels, and the operating rate of each channel can reach 25G. The transmission distance is 70m when used with OM3 multimode fiber and 100m when used with OM4 multimode fiber. 2) 100G QSFP28 SRBD Interface type: multimode duplex LC working principle The transmission wavelength of the 100GBASE-SRBD optical module is 850nm and 900nm, and the SWDM wavelength division multiplexing technology is used to multiplex the optical signals of different wavelengths in the same...
