100G Ethernet has the advantages of higher transmission rate, higher density and lower power consumption, so it is welcomed by the market. 100G QSFP28 products include 100G QSFP28 optical module, 100G QSFP28 AOC active optical cable and 100G QSFP28 DAC high-speed cable. Today ETU-Link will introduce the comprehensive wiring solution of 100G QSFP28 network in detail.

Recommended solution for 100G network generic cabling:

100G QSFP28 DAC: Link length 1-5m

The 100G QSFP28 DAC high-speed cable includes QSFP28 to QSFP28 DAC and QSFP28 to 4xSFP28 DAC, which can be used for connection between server and switch, memory and switch, switch and switch. QSFP28 DAC is an ideal solution to replace 100G optical module for 100G short distance connection. If it is necessary to connect equipment within 5m, 100G QSFP28 DAC and 100G QSFP28 to 4×25G SFP28 DAC are good choices.

100G QSFP28 AOC: Link length 5-30m

The 100G QSFP28 AOC active optical cable, including QSFP28 to QSFP28 AOC and QSFP28 to 4×25G SFP28, can be used for the connection between server and switch, memory and switch, switch and switch. If the equipment connection within 30m is needed, 100G QSFP28 AOC is recommended.

100G QSFP28 SR4/PSM4 optical module: Link length 30-500m

The transmission distance of 100G SR4 optical module can reach 100m when using with 12 core MTP OM3 / OM4 optical fiber patch cord, while that of 100G psm4 optical module can reach 500m.

100G QSFP28 CLR4/LR4/ER4 optical module: 2-40km

The transmission distance of 100G CLR4 optical module and 100G LR4 optical module is 2km and 10km respectively, while 100G-ER4 optical module has achieved a great leap, and the transmission distance has directly expanded to 40km. In addition, they can be used with LC single-mode duplex fiber patch cords with high-quality LC/UPC connectors, and it can realize the fiber interconnection with low insertion loss.

To sum up, network cabling can be selected according to requirements. For short-distance connection, it is recommended to select DAC / AOC, which is cheaper than optical module. ETU-Link can provide users with efficient optical network application connection scheme.
