自GPT点燃人工智能产业浪潮以来,全球资本市场的叙事重心几经转移。从最初的核心算力芯片,到高带宽存储,再到电力与散热基础设施,每一个阶段都有相应的硬件赛道成为市场焦点。而当前,聚光灯正照向一个曾经相对边缘的环节——光通信与光模块。而这轮的炒作也是AI硬件演进至2026年后物理极限倒逼的必然结果。理解这一逻辑,有助于把握当前AI产业链的核心瓶颈所在。
一、算力瓶颈的递进:从“算力荒”到“互联墙”
回顾AI硬件投资的脉络,每一次瓶颈的转移都催生出一批核心受益标的。
2023年:算力荒。 大模型密集发布阶段,最稀缺的资源是算力芯片。英伟达的GPU与掌握CoWoS先进封装产能的台积电,成为产业链的绝对核心。
2024年:内存墙与电力墙。 算力提升后,数据传输速度成为新的制约因素;同时,大规模集群运行带来显著的电力负荷压力。HBM(如SK海力士)和液冷温控(如维谛技术)解决方案因此迎来高速增长。
2025-2026年:互联墙。 这是当前阶段的核心瓶颈。AI算力集群已从万卡级别扩张至十万卡级别,GPU之间的数据交换量呈指数级增长。网络连接一旦拥堵,庞大的算力投资将无法有效释放。如何实现GPU之间的极速互联,便成为光通信产业链成为超级主线的底层逻辑。
二、光模块的核心驱动力:从“按年迭代”到“按月推进”
在超算中心内部,光模块承担着连接GPU的“数据通道”功能。其爆发式增长可归纳为三大核心驱动力:
(一)铜缆的物理极限。 在传统的短距离传输中,铜缆尚可胜任。但在当前800G甚至1.6T的超高传输速率下,铜缆的有效传输距离受到严格限制。在长距高速互联场景中,“光进铜退”已成为不可逆转的技术方向。需要说明的是,在机架内极短距离互联场景下,铜缆方案依然具备成本和低功耗优势,如英伟达GB200 NVL72即采用高速铜缆背板互联方案,铜缆连接数量高达5,184根。不过,随着GPU集群规模的持续扩大,铜缆在高速条件下的传输距离限制日益凸显,光通信方案的重要性正在快速提升。
(二)高速迭代与市场规模跃升。 在传统通信时代,光模块速率从100G提升至400G往往耗时数年。而在AI时代,云厂商直接以订单推动交付节奏。据Lightcounting测算,2026年全球光模块数据通市场规模预计达228亿美元,2026至2030年复合增速约为20%。中金公司指出,2026年全球光模块已进入800G全面普及、1.6T规模商用阶段,头部厂商中际旭创与新易盛已启动1.6T光模块的小批量出货。高端新品订单消化速度较快,叠加硅光方案带来的BOM成本下降,推动相关企业毛利率稳中有升。
(三)硅光子与CPO:技术迭代的下一阶段。 为满足高带宽、低功耗的系统需求,硅光子技术和光电共封装方案正成为产业格局重构的重要方向。银河证券数据显示,2026年800G光模块中硅光方案占比已超过50%,而在1.6T光模块中占比高达70%—80%。传统EML光芯片路线产能集中于海外,受限于磷化铟材料,2026年供给缺口较大,硅光方案成为缓解供应链压力的关键路径。与此同时,中金公司认为CPO已成为推动产业链新一轮升级的核心变量。
三、产业链格局:核心环节的定价权分布
在美股、A股与港股市场中,光通信产业链涉及多个细分环节,掌握核心定价权的公司各有侧重。
(一)美股:底层芯片与关键元器件的供应方
博通(Broadcom -AVGO)。 博通是光模块中DSP(数字信号处理器)芯片的核心供应商之一。高端DSP赛道呈现博通与Marvell双寡头垄断格局,双方凭借深厚的SerDes IP积累和PAM4编解码算法,几乎垄断了头部云厂商的1.6T DSP供应份额。1.6T主流方案中博通200G DSP表现较为突出,其400G DSP已发布上市,技术优势明显。但需注意,DSP先进制程芯片高度依赖台积电先进封装产能,台积电的产能排期直接影响高速光模块的放量节奏。
迈威尔科技(Marvell -MRVL)。 Marvell通过收购Inphi进入DSP市场,是博通在这一领域的主要竞争对手。在1.6T DSP供应格局中,Marvell与博通共同构成双寡头垄断。
Astera Labs(ALAB)。 该公司专注于PCIe Retimer芯片,解决单台服务器内部GPU与CPU之间的数据拥堵问题。其Aries PCIe重定时器产品线已被整合进英伟达Hopper平台,服务于主要美国超大规模数据中心客户。
(二)A股:封装与量产能力的集中地
中际旭创(300308.SZ)。 中际旭创是全球光模块领域的龙头供应商,其核心竞争优势在于新品导入能力和量产良率控制。从产业链动态来看,英伟达、谷歌、微软等全球顶级科技公司均在光通信领域展开积极布局,中际旭创作为核心供应商深度受益于这一趋势。公司800G光模块产品市占率连续两年位居全球第一,硅光技术的渗透率已超过一半。
天孚通信(300394.SZ)。 天孚通信在光器件领域拥有领先的精密封装和集成能力,是全球光器件行业的重要供应商之一。公司1.6T相关光引擎业务持续向好,已实现1.6T光引擎的规模量产。在前沿技术领域,公司前瞻布局CPO配套光器件,储备有高密度多通道FAU、ELS外置光源模组等核心产品,并持续布局硅光等下一代技术路线。
新易盛(300502.SZ)。 新易盛是光模块领域的另一家核心供应商,已具备800G及以上光模块的规模化量产能力,并成功批量交付最新一代1.6T产品。公司正积极推进3.2T、6.4T及12.8T等更高速率产品的研发。
(三)港股和相关企业
鸿腾精密(06088.HK)。 鸿腾精密业务中高速铜缆背板连接方案是机柜内短距离互联的有效路径之一。其增长受益于算力集群内部互联需求,但在光通信核心产品领域布局相对有限,与A股光模块龙头公司的主体业务存在差异。
长光华芯、索尔思光电等。 在EML光芯片领域,国内光芯片企业正在加速突围。长光华芯、索尔思光电具备IDM能力,正快速推进高端EML的送样与量产,成为填补海外供给缺口的重要力量。
四、展望:光通信之后的市场焦点
当光模块环节的认知趋于成熟,AI硬件演进的下一阶段或将引领资本市场的新一轮方向
端侧推理芯片:大模型推理请求若全部依赖云端处理,网络延迟与电力成本将面临较大压力。推进AI向终端迁移、实现本地推理已成为产业共识。端侧推理芯片有望迎来规模化落地的关键窗口期。
先进封装基板: 当前AI芯片封装面积不断扩大、功能复杂度持续提升,已逐步逼近有机基板的物理极限。玻璃基板具备低热膨胀系数、高平整度、低翘曲、高密度布线等优势,有望成为先进封装的下一个关键材料,延续封装密度和集成规模的进一步提升。从技术进展看,英特尔于2026年CES发布了首款采用玻璃核心基板进行量产的Xeon 6+处理器,苹果也已开始测试先进玻璃基板用于AI服务器芯片。台积电正加速推进玻璃基板与FOPLP融合方案,并计划于2026年建成迷你产线。
具身智能硬件: 大模型若缺乏物理交互能力,将无法完全作用于物理世界。当AI开始尝试与环境发生交互时,高精度六维力矩传感器、无框力矩电机、行星滚柱丝杠等机器人核心零部件也将随之迎来大规模资本涌入的重要拐点。
结语
从算力芯片到存储,从散热到互联,AI硬件瓶颈的每一次转移都带来新的投资主线。光通信与光模块作为当前“互联墙”环节的核心受益领域,其产业景气仍处于上行通道。中长期来看,端侧推理、先进封装与具身智能硬件亦是值得关注的方向。


The US Dollar was firmer Thursday, continuing its bounce from extreme oversold levels, the DXY peaking at 100.97, just short of the major resistance at the big 101 figure. A much lower than expected initial jobless claims figure saw a jump in US treasury yields, propelling the USD higher with the DXY having it biggest up day since May. AUD was the G10 outperformer, holding its own against the resurgent USD and easily outperforming its peers.
A hot jobs report where employment increased 32.6k vs an expected 15.4k and an unexpected fall in the unemployment rate, saw odds of a RBA rate hike next month jump to 43%, pushing the AUD higher. NZD underperformed on general risk aversion, seeing AUDNZD push higher into the overvalued “sell zone”. JPY saw losses, with USDJPY continuing it’s bounce off the 50% fib retracement at 137.30, pushing briefly through the psychological 140 level.
USD saw highs of 140.49 before finding selling at the 50-day SMA, pulling back to find support at its previous bullish trend line. Japanese CPI was released earlier today where a reading 0f 3.3% came in right as expected, JPY traders will be eyeing next weeks pivotal BoJ meeting where tweaks to their yield curve control policy are expected. EUR and GBP saw similar losses vs the USD, EUR initially boosted by a not as weak as anticipated flash Eurozone consumer confidence figure which coincided with a miss in US existing home sales.
Though it soon reversed to the downside with EURUSD hitting a low of 1.1119, managing to hold the key 1.1100 level. GBP continued to feel the effects of a softer UK CPI reading on Wednesday, with GBPUSD testing buyers around the key 1.2850 level, after losing sight of a Fib retracement level that helped contain declines on Wednesday. Today’s economic calendar is very light ahead of pivotal Central Bank meetings next week, with the only tier one release being only UK Retail Sales.


USD rallied modestly into month end with DXY pushing to the top of its recent range to again test the big 102 resistance level. The data highlight out of the US was the Chicago PMI figure which rose from the prior 41.5 to 42.8, but missing expectations of 43.3. in FedSpeak, Governor Goolsbee added little new from the FOMC statement last week stating he is “not sure when the Fed will be done raising rates and they are making good progress but will let the data guide them” and they may or may not hike in September. EUR was weighed on by the Dollar strength with EURUSD dipping below the psychological 1.10 level early in the session before finding support at the lower trend line.
A bounce on hot inflation data and a strong GDP out of the Eurozone saw EURUSD reclaim the 1.10 level, albeit unconvincingly. Currently, markets are pricing in around a 25-30% probability of a 25bp hike in September, with the ECB being “data dependant” any and all news regarding inflation out of the EU should see an impact on EUR. JPY was markedly weaker to start the week following on from the BoJ meeting on Friday.
During the Asian session yesterday, the BoJ offered to buy an unlimited amount of JGBs at a fixed rate in an unscheduled announcement in an effort to defend their new “flexible” yield control limits, a feeling of panic at the Japanese Central Bank saw selling in JPY, with USDJPY heading above 142, looking likely to test the BoJ resolve at the “intervention” zone of 145 in the near future. AUD and NZD predominantly outperformed, with AUD bring the clear winner on more talk from China regarding future stimulus, with AUDUSD rising through and holding the big figure at 0.6700. AUD traders also positioning for the RBA policy decision due today at 14:30 AEST, markets are currently split between a hike or hold following the lower than expected Aussie CPI data last week, with futures showing a 15.5% of a hike, but economists polled have it as much closer odds so could be an exciting meeting.
Todays Calendar below:


FX WRAP USD was choppy with the US Dollar Index ending the session flat in range bound trade. Unemployment claims dropped to 239k from 250k the prior week which was in line with consensus and having little effect on the USD, though Philly Fed Manufacturing figures did have a big beat coming in at +12.0 vs an expected -9.8, which was the highest print since April 2022. This, along with stubbornly high yields and a general risk-off background, saw the USD reverse some early weakness on Yuan intervention headlines.
DXY pushing its head above the resistance at July’s highs before stalling. JPY was the G10 outperformer against the USD. USDJPY now having eight straight days printing higher highs and higher lows, its longest streak since October's BoJ intervention-driven collapse from 32-year highs.
USDJPY hit a high in APAC trading of 146.56 on weak Japanese data, before fading to hit a low of 145.62. Not a peep out of the Japanese MoF yet but desks put the recovery down to yield differentials as US Treasury yields plateaued, while a poorly received Japanese JBG bond auction saw Japanese yields spike on the 30 years. Another currency on the intervention watchlist is the Chinese Yuan.
Bloomberg reports of Chinese authorities reportedly telling state banks to escalate Yuan intervention saw USDCNH have its largest drop of the month, breaking a 5-day rally. There is also theories floating around that China is funding Yuan intervention through selling US Treasuries, which would explain US treasury weakness (keeping yields elevated), which is unusual in an equity market risk off environment. AUD and NZD were the G10 underperformers again, AUD underperforming the NZD after a big miss in the Aussie employment report, where unemployment unexpectedly rose to 3.7% and jobs fell by 14.6k vs a 15k rise expected.
AUDUSD printed a low of 0.6366, but moved higher on the back of Yuan strength as the session went on. AUDNZD recovered the losses after the Aussie jobs report to move back above the key 1.080 level. Gold again moved lower, with XAUUSD breaking key support at 1892, after a test of the 1902 resistance early in the session was forcefully rejected.
The economic calendar is very light today, with only UK retail Sales being of any significance.


The long-awaited July FOMC meeting is finally upon us where rates markets are pricing in a sure thing for a 25bp hike (even a small chance of a 50bp), the question that traders will be looking for to be answered is “is this it?”. With a growing number of economists calling this the top in rates, butting up against the FOMC June statement and unwavering Fed speak since, giving guidance that there will be two more this year (including July if it happens). This sets traders up with an intriguing FOMC meeting, with the accompanying statement and Powell Presser sure to see some volatility as traders look for clues as to what’s to come.
With the background of recently cooling inflation, any language around the previously released June dot plots and whether they are still a reasonable estimate of future rate movements will likely be key. Fed Futures odds: Source: CME Fedwatch tool Tis seta traders up with some unique opportunities as the battle between the Market and the Fed should see some real volatility in both direction as market participants digest the statement and then Powell’s presser, which in the past, has contradicted somewhat traders perception of the statement. Charts to watch: DXY – The US Dollar Index It’s been straight up since mid-July after DXY bounced from extreme oversold levels, breaking through and holding the key S/R (and psychological) 101 level, which has held as support in the last couple of sessions.
Despite this recent rally DXY is still in the oversold half of it’s daily RSI, a hawkish Fed pushing back against the market today would likely see DXY push to test the next major S/R level at 102. A dovish Fed could see the recently established support at 101 seriously tested. In my opinion there is more chance of an upside surprise, given the market seems to be leaning towards pricing in a Powell capitulation.
US 10-year government bonds Government bonds are an asset. I think a lot of CFD traders are missing great opportunities in, in the current climate of rates and inflation taking center stage they are one of my favourite markets to trade with some great range trading opportunities. Looking at the chart of the US 10-year with the yields superimposed to see the negative correlation between the two (when you trade bonds, you trade the price, not yield) Over the last twelve months the yield on the 10-year has tested and subsequently struggled to stay above 4%, this turn lower in yields at this level gives a bond trader an opportunity by buying the bond price.
Todays FOMC should see some volatility in yields, I recommend keeping an eye on these over the coming days for some good trading opportunities as yields hit pivotal levels. Today’s FOMC decision is due out at 18:30 GMT


After surging close to 4% since early July off the back of a weakening USD, the EURUSD pair has stabilised around $1.123. With very little volatility seen this week in the pair, eyes now turn to the euro, as the European inflation data is set to be released today. Analysts are predicting a continued downward trend in inflation, with a Year-on-Year forecast of 5.50%, which is below May’s figure of 6.1%.
If the inflation data comes in above forecasts, we may see a further increase in the EUR as investors move towards the potentially higher yields. On the technical front, the tightening of Bollinger Bands on the 4-hour chart is something to watch. The lack of movement in the EURUSD pair throughout this week has led to exceptionally tight Bollinger Bands, with levels not observed on this timeframe since 2021.
When Bollinger Bands contract significantly, it typically signifies a period of low volatility and suggests that a breakout or significant price movement may be on the horizon. The Relative Strength Index (RSI) is also in overbought territory on multiple timeframes, including the daily. This might suggest there is room for a cool-off before a further continuation higher.
However, with the European inflation data due today, the fundamental data might cancel out any technical signals.


After reaching the high of 1.1250, last tested in 2022, the EURUSD has been trading steadily lower and currently sits along the 1.0850 support level, formed by the 61.8% Fibonacci retracement level and the previous swing low from early July. Looking at the technical aspects, the Ichimoku cloud indicates continued bearish pressures, with the top of the channel providing dynamic resistance, highlighting further downside potential for the EURUSD. The current downtrend on the EURUSD has been driven by the European Central Bank’s (ECB) comments in July that there was no clear bias in favour of hiking or holding rates for the upcoming meeting in September.
Coupled with the increasing likelihood of another rate hike to come from the US FOMC in September, as the Fed continues to fight inflation, strength in the DXY has led to the EURUSD trading lower. While a brief retracement could be likely to retest the upper bound of the channel, look for the EURUSD to maintain within the bearish channel. If the price breaks below the support level of 1.0850, this could signal a confirmation of further downside, with the next key support level at the previous swing low, along the 1.0650 price level.
