【应用】误码率极低的抗辐射光收发器成功用于SES-17卫星，总吞吐量超过15Terabit/s

时间： 2021-12-02 来源：Smiths Interconnect

技术问答

SES-17 是地球同步轨道上的超高通量卫星 (VHTS)，于 2021 年 10 月 22 日从位于法属圭亚那库鲁的阿丽亚娜航天公司圭亚那航天中心成功发射。由 Thales Alenia Space 建造的 SES-17 多任务 Ka 波段卫星将提供横跨美洲、加勒比海和大西洋的全面覆盖。这颗采用尖端技术的超高吞吐量地球静止 (GEO) 卫星位于西经 67.1 度的轨道位置，将为在航空、海事、企业和政府市场运营的 SES 客户提供最佳连接体验。

Smiths Interconnect Canada Inc.（前 Reflex Photonics Inc.）很荣幸成为 SpaceABLE® 抗辐射光收发器的供应商，该收发器是 SES-17 有效载荷数据路径的支柱。 SpaceABLE® 系列允许互连和路由超过 15 Terabit/s 的总吞吐量，并允许使用完整的 Ka 波束天线带宽，同时比铜互连更轻且可扩展。

SpaceABLE® 收发器经过精心设计，可承受 >100 krad (Si) 的辐射剂量。这些模块在 –40 ºC 至 85 ºC 的工作温度范围内以每通道高达 28 Gbps 的速度运行，误码率极低，预计使用寿命超过 20 年。

Smiths Interconnect 空间光互连产品线经理 Guillaume Blanchette 表示：“在过去的 5 年中，Smiths Interconnect 进行了大量投资，以建立全面的空间测试计划，以使 SpaceABLE 系列符合空间应用的要求。看到我们的产品在像 SES-17 这样的突破性卫星中使用并发挥如此重要的作用，这是一项伟大的成就，也证明了我们的工程能力和我们严格的空间认证方法。”

SES-17是一颗高度灵活且功能强大的卫星，它融合了尖端技术，旨在为客户提供最佳的连接体验。 SES-17 全数字有效载荷使用泰雷兹阿莱尼亚航天公司的第 5 代数字透明处理器 (DTP)，可实现无限交换/路由和频率转换等独特功能，同时提供比传统卫星高十倍的吞吐量。此外，数据路径、带宽和功率都可以即时更改，以满足客户不断变化的需求和实时流量需求。

SpaceABLE® 系列为 SES-17 有效载荷提供以下优势：

密度：小于6mm高（模块和中介层）

坚固性：承受辐射剂量 >100 krad (Si) 并符合 MIL-STD 883 冲击和振动标准

持续时间：预期寿命长达 20 年

性能：在 –40ºC 至 85ºC 的推荐工作温度范围内高达 10.3125 Gbps/通道

低功耗：115 mW/通道（<10 pJ/位）

Smiths Interconnect’s Isolator is Connecting with (Potential) Life on Jupiter’s Moons

It was a galactic effort. No surprise, then, at the site’s pride in knowing JUICE’s first transmission was successfully made and received. Nor that the team saved JUICE’s July 2031 date of arrival at Jupiter, after which Smiths Interconnect’s isolator will be helping to relay data that is highly relevant to Earth’s immediate future.
