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。


A raging US equity market fuelled by soft data, a drop in treasury yields and blowout earnings from NVDA (which saw its stock price hit an all-time high) saw risk-on trading through Wednesdays session. USD was choppy on Wednesday with an initial rally in DXY, which saw it briefly pierce the major resistance at 103.60, dramatically reversing course on big misses in US Manufacturing and Services PMIs which showed the US economy contracting faster than forecast. DXY hovering just above lows of 103.30 at the close after the earlier rally (driven by EUR weakness after their own PMIs disappointed) saw a high of 103.980.
AUD and NZD were among G10 outperformers, with AUD benefitting more from the risk-on sentiment outperforming the NZD to see AUDNZD hit a 10 day high of 1.0846. Rallies in iron ore and gold prices also helping the AUD. AUDUSD continued its bounce from the 0.6400 support level to highs of 0.6482, the next key level is the big figure at 0.6500 which until recently had been major support and now likely to be the next resistance level and certainly a key level to watch.
GBP was the G10 underperformer as dire PMI readings saw the Sterling Bears in charge. Services and Manufacturing figures all sharply declined, slipping into contractionary territory. GBPUSD printed a low of 1.2616 after the figures after hitting a high of 1.2717 earlier in the session.
GBPUSD did bounce back to regain the key 1.2700 level in the US session though, recouping most of its losses on positive risk sentiment and the USD slide on its own weak PMI figures. JPY outperformed with tumbling US treasury yields saw rate differentials tighten, taking the pressure off the USDJPY. USDJPY crashed below the key “intervention” level at 145 after printing an earlier high of 145.89.
The Yen was also supported by a beat in Japanese PMI data. The next big data point for Yen watchers will be the Tokyo CPI figure released tomorrow, with the 145 level key to the next move in USDJPY. Gold blasted higher in Wednesday’s session, blowing through the 1902 resistance level and not finding any real selling until 1920, the high set back on 11 th of August.
A weak USD and more importantly catering US Treasury Yields lending a big tailwind to the precious metal. In today’s economic announcements, not much in the way of tier one releases with Jackson Hole looming on Friday. US unemployment claims being the headline.


Global markets were buffeted by a risk-off catalysts in Tuesdays session. Weak Chinese trade data, hawkish Fed-speak and a Moody’s downgrade of US regional banks saw stocks and yields tumble FX Markets USD was firmer Tuesday in a session that was firmly risk-off following the Chinese trade data and Moody’s downgrade. Later in the session we also had the Fed’s Harker who said barring any "alarming" new data by mid-September he believed "we may be at the point where we can be patient and hold rates steady", dashing traders hops of a Fed pivot anytime soon.
DXY printed a high of 102.800, falling just short of the July 3rd high of 102.84 where it found resistance just under the round 103 figure and it’s June/July trendline. Risk sensitive AUD and NZD were the G10 underperformers, with NZD performing mildly worse than its AUD counterpart. Both NZD and AUD were weighed on by the aforementioned risk-off tone and dismal Chinese trade data.
AUDUSD hit a low of 0.6497, briefly breaking the major support at the 0.65 big figure before finding some bids, 0.6500 looking to be a key level. NZDUSD bottomed out at 0.6035 ahead of the closely watched New Zealand inflationary forecasts today. EUR, CAD, and GBP were all weaker to varying degrees against the USD due to the risk-averse trading conditions and the general USD strength as opposed to anything currency specific.
USDCAD traded up to 1.3501 until paring gains as a rally in crude oil lent the CAD some support. EUR saw little reaction to the ECB June Consumer Inflation Expectations survey which downgraded the 12-month and 3-year inflation forecasts. EURUSD losing hold of the psychological 1.10 handle, hitting a low of 1.0930 before recovering modestly.
JPY weakened with USDJPY continuing its march to the 145 “intervention” zone. JPY’s haven demand offset by BoJ doubts after Japanese wage data suggested the BoJ has less scope to reduce its easy policies. USDJPY trading to a high of 143.49, testing its August highs.
Today’s calendar:


US equity markets snapped a record-breaking run of up sessions in Thursdays trading, with the Dow Jones looking set to close in the green for a 14 th straight session (for the first time since the Dow’s inception), before seeing a sell-off on rising yields after a report that the BoJ is looking to tweak their YCC at their meeting today. FX Markets USD bounced back from its post-FOMC weakness with the Dollar supported by rising US Treasury yields after beats in US GDP and employment data and the aforementioned hawkish report regarding the BoJ. US 10yr yields surged over the 4% level, an area recently that has marked the top in yields.
With Powell stressing that the Fed would be “data dependent” going forward as to rate increases the hot US data saw traders shifting hawkishly on rates, this saw the US Dollar Index surge through the 101 level, hitting 2-week highs and looking to test the major resistance at 102. Todays PCE Index figure will be another piece in the Fed puzzle, and is likely to move the USD and yields on it’s release. EUR pushed higher early in the session until the ECB meeting where the market took comments from President Lagarde as dovish, seeing EURUSD hit a low of 1.0967, breaking through the support at 1.10, holding below with 1.10 now looking like resistance..
The ECB did hike rates 25bp as expected but it was Lagarde’s comments that she does not believe that more work needs to be done, given the current data, implying future meetings could be a hike or a hold, that saw EUR moving. Later today, some key German inflation figures will be released, EUR volatility should be expected. JPY saw big gains on Thursday, with USDJPY sliding from highs of 141.31 to hit a low of 138.75 after reports in Nikkei that the BoJ are to discuss a YCC tweak at today’s pivotal monetary policy meeting.
Noted however, similar rumours have been reported on in the recent past, so really nothing new. The overreaction in JPY shows how jittery FX traders are going into today’s meeting, it is likely we’ll see some big moves in the Yen in today’s session as well, whichever way the BoJ goes. Calendar:


USD was mostly firmer in Tuesday’s session as a mixed equity markets saw some slight risk-off conditions. Also support USD was rates markets shifting hawkishly (September meeting now pricing a 16% chance of a hike) ahead of Jackson Hole and Fed Chair Powell speaking on Friday. Fed member Barkin spoke but added little new, as he noted consumer spending and economic strength make it possible the US economy could reaccelerate before inflation cools.
DXY hit a high of 103.710, pushing slightly above July and last week’s high and resistance area after testing support at 103.00 earlier in the session. EUR and GBP were both lower against the USD to varying degrees, EUR was the G10 underperformer with EURUSD hitting a low of 1.0834 and EURGBP testing the bottom of its recent range and major support at 0.8500. Both EUR and GBP traders have key PMI figures to navigate today, with readings in manufacturing and services for both currencies.
AUD, NZD and JPY were all firmer against the USD, with NZD outperforming, seeing AUDNZD dip below the psychological 1.0800 level briefly. Both NZDUSD and AUDUSD managed to hold their major support levels at 0.5900 and 0.6400 respectively. With Kiwi and Aussie traders having NZ retail sales and Australian flash PMIs to look forward to today.
USDJPY dropped 146.00, trading in a range between 146.39-145.50 ahead of Japan’s preliminary PMIs, JPY supported by a double top and forming in USDJPY. Despite overall USD strength, with some help from a soured risk sentiment, XAUUSD attempted to retake the 1902 resistance/support level. The move however was strongly rebuked as sellers entered the market at that key level, holding XAUUSD in its 2-week range.
Todays Calendar:


USD was marginally lower in Tuesdays session, trading in a tight range amid thin newsflow and market participants awaiting the key June CPI reading released later today. After breaking the psychological 102 level in Mondays session, DXY tested a re-entry into the range but found the previous support at 102 acting as stiff resistance, seeing DXY finish at the session lows around 101.65. NZD was the G10 underperformer with NZDUSD hitting a low of 0.6168 where it found support at Mondays lows as the currency traded defensively ahead of the RBNZ rate decision today.
Futures markets are expecting rates will be held at 5.5%, confirming the RBNZ as being the first developed Central Bank to reach the end of its tightening cycle. AUD was marginally firmer against the USD, after initially struggling in tandem with the Kiwi before later reversing losses on a USD pull-back. AUDNZD moving higher, back above the mid-price of it’s 2023 range.
Safe-havens, JPY and CHF, saw gains despite risk-on equity markets on some defensive positioning ahead of big data releases later in the week. USDCHF retraced from a peak of 0.8863 to a low of 0.8791 with the cross pair hitting its lowest level since January 2021. USDJPY traded between 141.46-140.17, continuing its strong down move after testing the 145 “intervention” zone last week.
USDJPY appears one of those most at risk of any upside surprises in the US CPI data given its sharp decline over recent sessions. GBPUSD saw gains with Cable breaking it’s 1.2850 resistance level, surpassing 1.2900 to a peak of 1.2934, its highest level in over a year. A strong UK Labour market figure saw futures markets re-price a 50bp hike as the favoured outcome of the BoE policy meeting on August 3 rd, driving gains in the Pound.
EUR was flat with EURUSD just about clawing back above 1.10 at the US session end amid a USD pullback, with EURUSD trading in a narrow range despite a weak German ZEW survey. CAD saw slight gains against the USD, bolstered by the continued upward momentum in crude oil with WTI crude settling at 10-week highs and seeing USDCAD break its 4h trendline. CAD traders have the BoC rate decision later today to look forward to, where after a five-month ‘pause’, the consensus looks for rates to be lifted by 25bps for the second straight meeting, taking its key rate to 5.00%


USD was higher on Thursday, with The Dollar Index bouncing back strongly from Wednesdays decline, breaking through the resistance level of 103.60 to touch on the weekly highs at the big 104 level and hitting overbought levels on the daily RSI. Market risk-off, rising yields and a lower than forecast jobless claims figure giving the USD a boost as good news is bad news for equities which in turn is good news for the USD (if that makes sense!) Looking ahead to Friday’s session, all attention will be on Fed Chair Powell speaking at Jackson Hole 14:05 GMT, we are sure to see some volatility in USD as traders look for hawkish or dovish clues from the Fed chair. AUD, NZD, and CAD all saw losses to varying degrees against the USD on broad risk-off sentiment resulting in haven flows to the USD.
CAD was the “least worst” with a rally in oil prices supporting CAD somewhat. Risk sensitive AUD and NZD were the underperformers with both AUDUSD and NZDUSD giving back all their Wednesday gains and then some. AUDUSD and NZDUSD both sliding to test their major support levels at 0.6400 and 0.5900 respectively.
Again, these will be key levels to watch as we head into Jackson Hole. EUR and JPY both also saw losses against the USD, but not as deep as the more risk sensitive cyclical currencies above. EURUSD managing to defend the psychological 1.0800 level, which was the support level set in Wednesday’s session and also the 200 Day MA level.
USDJPY held beneath 146.00, but still well above the key 145 level, rising US yields pushing this pair higher, but held back somewhat by the safe haven status of the Yen. In risk events for today and the weekend, all eyes will be on the Jackson Hole Symposium, where the main event will be comments from Fed Chair Jerome Powell, also on the docket will be other Fed speakers and ECB President Lagarde.
