Moving Forward- Optical Transceiver 400G And Beyond
(2022年)https://www.primus-it.com/products/telecom-network-products/
Due to the ongoing large increase in bandwidth demand, Data Center connections are expected to move from 25G/100G to 100G/400G.
Within the Data Center Racks
• 10GE still being deployed
• 25GE starting to be deployed in volume
• 100GE (or 50G) will follow
Between Data Center Racks
• 40GE still being deployed
• 100GE starting to be deployed in volume
• 400GE will follow at large Cloud Service Providers
Long Spans/DCI & WAN
• 10G DWDM/Tunable still being deployed
• 100G/200G Coherent starting to be deployed
• 400G Coherent will follow – Then 600G or 800G
Following the market situation, 400G is a priority for the large DC (intra-DC application) and, at a lower scale, for the Telco transmission department.
400G is coming with 2 form factors for the Access/Intra-DC:
- QSFP56-DD (also called QSFP-DD for QSFP Double Density)
- OSFP (for Octal SFP)
EPON 10g and GPON 5g are two typical passive optical networks (Passive Optical Networks, PONs), which belong to short-distance optical cables. They are often used in urban areas to realize Internet surfing, Internet voice and transmission network telecom. They can also be used in cellular base stations. Backhaul connection, Wi-Fi hotspot communication, and even distributed antenna array. The biggest difference between the two is that the download and uplink communication protocols are different.
As one of the professional fiber optic transceiver manufacturers, Primus IT specializes in the development and manufacture 100 bases to 400G optical transceivers including GBIC, SFP, SFP+, SFP28, QSFP+, QSFP28, XFP, XENPAK, X2, CFP, CFP2, AOC, DAC, etc. Primus IT provides cost-effective transceivers solutions for customers worldwide in data communications, long-distance transmission, wireless networking and more.
