Ciena’s Vesta 200 6.4T CPX Optical Engine delivers best-in-class NPO performance

1 00:00:00,166 --> 00:00:02,627 Hi, I am Thai Son Le, 2 00:00:02,627 --> 00:00:05,422 I am a system architect here at Ciena. 3 00:00:05,422 --> 00:00:07,632 Today I am in our New Jersey lab, 4 00:00:07,632 --> 00:00:09,634 to show you a demonstration of our 5 00:00:09,634 --> 00:00:11,636 Vesta optical engine. 6 00:00:11,636 --> 00:00:14,806 The Vesta 200 6.4T per second 7 00:00:14,806 --> 00:00:19,811 CPX optical engine is a 32 times 200Gbps 8 00:00:19,811 --> 00:00:20,979 pluggable module 9 00:00:20,979 --> 00:00:24,733 for CPO and NPO applications. 10 00:00:24,733 --> 00:00:26,943 The module is designed in accordance 11 00:00:26,943 --> 00:00:31,406 with an Open CPX MSA 1.0 specification. 12 00:00:31,406 --> 00:00:33,491 The device’s compact form factor 13 00:00:33,491 --> 00:00:36,536 make it highly suitable for high density 14 00:00:36,536 --> 00:00:39,664 applications up to 200 terabit per second. 15 00:00:39,664 --> 00:00:41,583 In today's demonstration, 16 00:00:41,583 --> 00:00:43,209 we will show you how Vesta’s 17 00:00:43,209 --> 00:00:44,419 superior performance 18 00:00:44,419 --> 00:00:45,879 makes this optical engine 19 00:00:45,879 --> 00:00:47,213 an outstanding choice 20 00:00:47,213 --> 00:00:48,840 for a new generation of 21 00:00:48,840 --> 00:00:54,095 CPO/NPO based scale up and scale out networks. 22 00:00:54,095 --> 00:00:56,181 Delivering outstanding performance 23 00:00:56,181 --> 00:00:58,308 is especially important in linear 24 00:00:58,308 --> 00:00:59,726 interconnect systems 25 00:00:59,726 --> 00:01:02,103 that saves a tremendous amount of cost 26 00:01:02,103 --> 00:01:06,524 and power by eliminating DSP-based retimers. 27 00:01:06,524 --> 00:01:08,109 So let's jump in! 28 00:01:08,109 --> 00:01:08,943 In this setup, 29 00:01:08,943 --> 00:01:11,071 we have an external laser source 30 00:01:11,071 --> 00:01:12,864 from O-Net, with eight channels, 31 00:01:12,864 --> 00:01:14,949 which delivers optical power to 32 00:01:14,949 --> 00:01:17,660 Vesta 200 optical engine. 33 00:01:19,162 --> 00:01:20,205 Vesta 200 34 00:01:20,205 --> 00:01:21,206 optical engine 35 00:01:21,206 --> 00:01:23,208 sit on the evaluation board 36 00:01:23,208 --> 00:01:24,292 under the heatsink, 37 00:01:24,292 --> 00:01:25,668 as you can see here. 38 00:01:25,668 --> 00:01:28,755 In an actual system, Vesta 200 39 00:01:28,755 --> 00:01:30,965 will be liquid cooled. 40 00:01:30,965 --> 00:01:34,260 Next we have a pattern generator here. 41 00:01:34,260 --> 00:01:35,970 In this case it is a 42 00:01:35,970 --> 00:01:38,681 MaxLinear SERDES evaluation board 43 00:01:38,681 --> 00:01:41,768 and we're sending out PRBS 31. 44 00:01:41,768 --> 00:01:42,936 The electrical signal 45 00:01:42,936 --> 00:01:44,521 from the MaxLinear EVB 46 00:01:44,521 --> 00:01:46,022 are routed to the Vesta 47 00:01:46,022 --> 00:01:47,565 to the optical engine, 48 00:01:47,565 --> 00:01:49,943 through the electrical channel on the EVB 49 00:01:49,943 --> 00:01:52,445 and electrical cable here. 50 00:01:52,445 --> 00:01:54,197 The electrical channel loss 51 00:01:54,197 --> 00:01:56,491 is about 15dB. 52 00:01:56,491 --> 00:01:58,785 While it is still within the Open CPX 53 00:01:58,785 --> 00:02:01,621 maximum loss budget of 18dB, 54 00:02:01,621 --> 00:02:06,417 the channel could still be characterized as challenging. 55 00:02:06,417 --> 00:02:08,419 After the long host channel 56 00:02:08,419 --> 00:02:10,505 data arrives at the Vesta 57 00:02:10,505 --> 00:02:14,008 optical engine, which is under the heatsink. 58 00:02:14,008 --> 00:02:16,594 Now, looking at the line side of the Vesta 200 59 00:02:16,594 --> 00:02:19,055 optical engine, we have a single channel 60 00:02:19,055 --> 00:02:20,974 routed to the optical scope 61 00:02:20,974 --> 00:02:23,268 to show the TP2 performance, 62 00:02:23,268 --> 00:02:25,854 As we touched on earlier, 63 00:02:25,854 --> 00:02:27,730 delivering strong performance 64 00:02:27,730 --> 00:02:30,984 is especially critical in linear systems. 65 00:02:30,984 --> 00:02:33,611 We can see that the Vesta 200 transmitter 66 00:02:33,611 --> 00:02:36,030 offers excellent TP2 performance, 67 00:02:36,030 --> 00:02:37,949 with TDECQ of 2.7dB, 68 00:02:37,949 --> 00:02:40,410 Extinct Ratio of 4.4dB 69 00:02:40,410 --> 00:02:42,537 and OMA of 2dBm, 70 00:02:42,537 --> 00:02:45,582 including 1dB of optical loss in the set up. 71 00:02:45,582 --> 00:02:47,792 This provides excellent margin 72 00:02:47,792 --> 00:02:50,837 to the IEEE 802.3dj spec 73 00:02:50,837 --> 00:02:54,674 that is adopted by the Open CPX MSA. 74 00:02:54,674 --> 00:02:57,677 Meeting the TP2 performance is often cited 75 00:02:57,677 --> 00:02:59,512 as the most critical challenge 76 00:02:59,512 --> 00:03:02,432 of linear interconnect optical systems, 77 00:03:02,432 --> 00:03:03,641 and we are showing here 78 00:03:03,641 --> 00:03:06,686 that Vesta 200 meets the critical requirement 79 00:03:06,686 --> 00:03:08,354 with plenty of margin. 80 00:03:09,105 --> 00:03:10,940 Now, on to the Vesta 200 81 00:03:10,940 --> 00:03:13,067 receiver side performance, 82 00:03:13,067 --> 00:03:16,696 Vesta 200, receive up to 32 optical channels 83 00:03:16,696 --> 00:03:18,281 and then converts them back 84 00:03:18,281 --> 00:03:20,658 to the electrical signal internally, 85 00:03:20,658 --> 00:03:21,784 using high bandwidth 86 00:03:21,784 --> 00:03:25,788 photodetector and transimpedance amplifiers. 87 00:03:25,788 --> 00:03:27,624 The electrical signals are routed 88 00:03:27,624 --> 00:03:31,461 back to the MaxLinear SERDES receiver to electrical bus 89 00:03:31,461 --> 00:03:34,505 with approximately 15bB loss. 90 00:03:34,505 --> 00:03:39,427 The signals are then equalized and BER are computed. 91 00:03:39,427 --> 00:03:41,763 Here we see great pre-FEC BER 92 00:03:41,763 --> 00:03:44,891 in the range of 1e-10, e-11, 93 00:03:44,891 --> 00:03:50,146 with plenty of margin to the IEEE spec of 2e-4. 94 00:03:50,146 --> 00:03:52,523 Again, this performance has been delivered 95 00:03:52,523 --> 00:03:53,524 with challenging 96 00:03:53,524 --> 00:03:55,151 host electrical channels 97 00:03:55,151 --> 00:03:57,570 on either end of the data path. 98 00:03:57,570 --> 00:03:59,072 This demo has highlighted 99 00:03:59,072 --> 00:04:03,368 how the Vesta 200 6.4T per second CPX 100 00:04:03,368 --> 00:04:05,703 delivers excellent performance in an 101 00:04:05,703 --> 00:04:07,997 ultra-compact CPX form factor 102 00:04:07,997 --> 00:04:09,707 that is ideally suited 103 00:04:09,707 --> 00:04:11,668 for a new generation of scale up 104 00:04:11,668 --> 00:04:13,878 and scale out networks. 105 00:04:13,878 --> 00:04:16,297 Thanks for joining me in the Ciena lab 106 00:04:16,297 --> 00:04:20,760 for an inside look at Vesta 200 6.4T per second 107 00:04:20,760 --> 00:04:22,804 Open CPX technology.
