This edition of the Friday 5 is brought to you by the number 400 -- as in 400 Gigabit Ethernet. Also on tap are submarine network advances, software defined access network advances, and interest in disaggregated optical hardware advancing.
The IEEE expects LANs to see the light, Nokia isn't buying, AT&T wants to buy but the DoJ won't let them, and other optical communications related news from the past two weeks are all detailed in this week's Friday 5 video.
AT&T opens up XGS-PON, Sprint and Cox join up for small cells, the OIF dishes up CEI 4.0, and China may not be as much of an up market for mainstream component suppliers. Lightwave Editorial Director Stephen Hardy brings you up to speed.
