100G long-haul transmission is also quickly maturing，Which primarily fuels the need for reliable, high-performance 100G optics and technology innovations. So how 100G modules and market will evolve in coming years to keep up with the unprecedented data traffic?
There are six leading 100G transceiver form factors on the market: the CXP, CFP, CFP2, CFP4, QSFP28 and CPAK, among which 100G QSFP28 modules, with the most compact size and less power consumption, are the major 100G module of choice in data centers and enterprises.
100G optical transceiver manufacturers compete to refine the product and push its versatility, and the continued adoption of 25GE between servers and ToR switches will push adopters of 25GE to upgrade to 100GE. 100G switch port shipments will outnumber 40G switch port shipments—as 25G server and 100G switch became commonplace in most hyperscale data centers that replace previous 10G servers and 40G switches.100G transceiver modules deployment is growing sustainably and has now become the fastest Ethernet connections in broad adoption. On the contrary, The market for 40GE has seen a shift to shrink rapidly while the demand for 10GE will only see flattish growth. It is predicted that 40G will be only deployed if 100G cannot be used due to technical or compatibility issues or low cost. With that being said, 100G optical modules will continue to remain strong as the supply bottleneck is getting resolved.
