AI推动800G光模块加速渗透，美银唱多思科与Ciena

智通财经05-27

美国银行(BofA)周二上调了Ciena科技与思科的目标价，该投行认为光网络市场的增长势头依然“坚韧”。分析师Tal Liani在给客户的报告中指出，思科近期公布的2026财年第三季度业绩，以及关于Acacia业务需求持续强劲的表述，使得该行对光网络底层需求环境保持乐观。Liani同时维持对Ciena和思科的“买入”评级。思科于2026年5月14日公布了2026财年第三季度财报，业绩表现强劲，营收...

Liani在给客户的报告中指出，思科近期公布的2026财年第三季度业绩，以及关于Acacia业务需求持续强劲的表述，使得该行对光网络底层需求环境保持乐观。Liani同时维持对Ciena和思科的“买入”评级。思科于2026年5月14日公布了2026财年第三季度财报，业绩表现强劲，营收和盈利均实现两位数增长，并超出此前指引上限。公司实现了创纪录的158亿美元总营收，同比增长12%。产品营收达到121亿美元，增长17%，主要受到AI基础设施和园区网络需求的强劲推动。Liani写道，思科披露，第三季度Acacia订单额超过10亿美元，其中AI相关光器件收入同比增长近4倍，达到约9.5亿美元;此外，超大规模数据中心对非AI光器件的需求也贡献了额外增长。该行展望从400G向800G可插拔光模块的迁移趋势，认为思科与Ciena均处于有利位置，有望在这一快速增长的光网络周期中继续保持市场份额领先。该行上调了对两家公司的盈利预测，以反映其在AI相关基础设施建设中强劲的光网络参与度。将思科的目标价从114美元上调至135美元(基于2027年预期企业价值/自由现金流的29倍，此前为25倍)，将Ciena的目标价从550美元上调至660美元(基于2027年预期市盈率的69倍，此前为62倍)。随着超大规模数据中心运营商加速升级基础设施，高速光网络技术正从400G向800G快速迁移。美银预计，全球800G ZR/ZR+光学市场规模将在2026年扩大近十倍，在整体光学市场中的占比将从2025年的4.6%大幅跃升至2026年的35.5%。思科目前在800G细分市场占据约50%以上的份额，Ciena约占30%;不过Ciena因拥有更为节能的3nm DSP技术，预计其市场份额将继续提升。思科旗下Acacia光学业务的强劲表现最能说明这一趋势——第三季度Acacia订单超过10亿美元，AI相关光器件收入同比增长近4倍，400G和800G相干可插拔光模块已分别出货超75万个和超4万个，2026整个财年有望实现超过200%的同比增长。","kind":"news","is_publish_news":true,"is_publish_highlight":true,"is_publish_live":false,"is_publish_wemedia":false,"editions":null,"column":"","sentiment":"1","news_tag":"corporation","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":1,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
