25G SFP28 transceivers also play in critical role in meeting the growing bandwidth demand in next generation access networks such as 5G wireless. While interface developments, like the recently released eCPRI specifications, will help improve bandwidth efficiency, the 5G wireless infrastructure will require significantly higher capacity in the optical links. Compact, power and cost efficient 25G transceivers supporting both Ethernet and CPRI-10 while exposed to the elements will play a key role in supporting the rollout of this next generation wireless infrastructure.
