The guidance is soft for next quarter and it mentions Century Link delay in closing will continue to have a negative effect:

"Now turning to our outlook for the fourth quarter of 2017, we currently project revenue of $190 million, plus or minus $5 million. The midpoint of this range is slightly down on a sequential basis and up 5% on a year-over-year basis. This expectation reflects our anticipation of a continued ramp in the CX2 and XT Series, offset by a further decline at the new CenturyLink due to the delay in the transaction closing and softness at certain ICP customers. In Q4, we also anticipate the initial revenue contributions from our recently launched XTM II 16QAM metro edge platform, although we expect more substantial contributions over the course of FY 2018 as key existing customers adopt the platform. As it is always difficult to predict weather and to what extent we could benefit from year-end budget flush, we have not made much upside into our guidance."
