太字节红外传输（TBIRD）计划将建立一条从低地球轨道（LEO）的6U立方体卫星到地面站的光通信链路，突发速率高达200gbps，单次传输的数据量可超过1tb。空间和地面终端利用商用1550纳米相干收发器与自动重复请求（ARQ）系统相结合，以保证在大气衰落信道存在下的稳健通信。这允许系统执行可靠的端到端数据传输，从有效载荷的2 tb存储缓冲区到地面终端。在本文中，我们描述了即将在2022年进行的TBIRD飞行演示的系统架构、链路分析和操作概念。我们还提供了JPL光通信望远镜实验室（OCTL） 3U终端有效载荷和地面终端发展的最新情况。
The Terabyte Infrared Delivery (TBIRD) program will establish an optical communication link from a 6U CubeSat in low-Earth orbit (LEO) to a ground station at burst rates up to 200 Gbps, resulting in data volumes that can exceed 1 Terabyte in a single pass. The space and ground terminals utilize com-mercially available 1550-nm coherent transceivers in conjunction with an automatic repeat request (ARQ) system to guarantee robust communication in the presence of an atmospheric fading channel. This allows the system to perform a reliable end-to-end transfer of data from the payload's 2-TB storage buffer to the ground terminal. In this paper, we describe the system architecture, link analysis, and concept of operations for the upcoming TBIRD flight demonstration in 2022. We also provide an update on the development of the 3U terminal payload and the ground terminal at JPL's Optical Communications Telescope Laboratory (OCTL).
