- Опубліковано 18 сер 2024
- Following the success of 400G ZR/ZR+ digital coherent optics (DCO), customers are looking for an 800G version of DCO to upgrade their transmission speed to the next level. Hyperscale data centers are driving the demand of 400G/800G DCO for data center interconnect (DCI) applications, while service providers are starting to adopt the concept of IP-over-DWDM using DCO modules for metro and regional networks. QSFPDD and OSFP are the most popular and compact form factors used in DCI applications. This new 800G transceiver uses Coherent’s 140 Gbaud IC-TROSA optical subassembly, which features a high-efficiency indium phosphide modulator and receiver combined with a proprietary embedded wavelength-tunable laser. The Coherent 800G QSFP-DD transceiver has several operating modes that enable it to deliver up to 1000 km of reach at 800 Gbps and up to 2000 km at 400 Gbps in well-designed networks. In this video, the module is demonstrated in 800G ZR mode covering over 9000 ps/nm of dispersion, equivalent to approximately 450 km of fiber.
