| Turning to our subsystems business group, we have the following highlights for the quarter. First, as I previously stated, we have samples available for our 400 gig XR pluggables, capable of supporting both point-to-point and industry leading point to multipoint applications. These samples are on time and performing well against our technical specifications and we're on track to see their financial impact beginning in the first half of 2023. Second, important to our systems business, we're integrating these 400 gig pluggable modules into our metro platforms. This is a high percentage of material content for our metro systems. This is the first time we've had the ability to produce our own vertically integrated metro solutions instead of buying components from the merchant market, which should result in future meaningful margin expansion and improved global competitiveness. Third, we're beginning to certify our 400 gig pluggables to work in external platforms as well, such as routers, switches, servers and wireless RAN. This will open up a new multi-billion dollar addressable market for us, while giving us additional revenue growth and margin expansion opportunities. We've partnered with leading equipment manufacturers to accelerate our go-to-market programs for our pluggables and are planning trials with tier ones in the second half of this year. |
