At present, with the rapid development of HD, massive video, cloud computing and big data, we-media, Internet of things and artificial intelligence, IP data traffic in global data centers is increasing year by year, and the demand for 100G optical modules is also increasing. Let's take a look at what 100G optical module actually has.
1, 100G QSFP28 SR4
The 100G QSFP28 SR4 optical module adopts 4-channel 25G NRZ multi-mode parallel technology and can transmit up to 70m or 100m through 12-core MPO jumper (OM3/OM4) multi-mode fiber. It is widely used in 100GBASE-SR4 Ethernet, OTN OTU4, 128GFC, InfiniBand 4x EDR.
2, 100G QSFP28 PSM4
100G QSFP28 PSM4 optical module adopts 4-channel 25G NRZ single-mode parallel technology, and the transmission distance can reach up to 2km through 12-core MPO jumper (G.652) single-mode optical fiber. It is widely used in 100G PSM4 Ethernet and InfiniBand 4x EDR links.
3, 100G QSFP28 CLR4
The 100G QSFP28 CWDM4 optical transceiver module uses four channels of 25G NRZ wavelength division multiplexing (CWDM4) technology and can transmit up to 2km through single-mode fiber. It is widely used in 100G CWDM4 Ethernet and InfiniBand 4x EDR links.
4, 100G QSFP28 LR4
The 100G QSFP28 LR4 optical module adopts four-channel 25G NRZ wavelength division multiplexing (LWDM4) technology and can transmit up to 10km through duplex LC interface OS2 single-mode fiber. It is widely used in 100GBASE-LR4 Ethernet and OTN OTU4 links.
5, 100G QSFP28 ER4
The 100G QSFP28 ER4 optical module uses 4-channel 25G NRZ wavelength division multiplexing (LWDM4) technology and can transmit up to 40km through single-mode fiber. It is widely used in 100GBASE-ER4 Ethernet and OTN OTU4 links.
The size of the 100G QSFP28 optical module is the same as that of the QSFP+ optical module. It also has four parallel data channels, but the transmission rate of each channel increases from 10Gbit/s to 25Gbit/s, thus achieving a transmission rate of 100Gbps.
