Ciena provided revenue guidance for the fourth quarter of 2021. For the quarter, the company expects to deliver revenue in a range of $1.00 billion to $1.04 billion. At the midpoint of this guidance range, revenue growth from the first half to the second half of fiscal 2021 would be approximately 26%. This would be a very strong second half performance, in line with the stronger-than-typical second half uptick that company forecast since the beginning of the year.
