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 current market consensus is that the Reserve Bank of New Zealand (RBNZ) would likely keep interest rates at 5.50% at the upcoming meeting on 12th July. This is supported by the RBNZ’s monetary statement indicating that “ monetary policy is having a sufficiently moderating effect on demand and inflation, and that we are yet to see the full effects of past tightening on the economy. A pause would also allow more time to assess the impact of the significant tightening, and the timing of any further increase that might be needed.” However, while the Consumer Price Index (CPI) has turned down from its peak of 7.3%, the most recent data was released at 6.7%, this is still significantly higher than the RBNZ’s target level of 1-3%.
Therefore, another rate hike from the RBNZ cannot be ruled out. In May, the RBNZ released its decision to hike rates to 5.50% but also indicated that the official cash rate has reached its peak at 5.50% but would need to remain at the restrictive level until at least the middle of 2024. This led to the NZDUSD falling steadily from 0.6250 to reach the round number support level of 0.60.
As the NZDUSD climbs toward the 0.6250 price area, formed by the previous swing high and the downward trendline, look for a potential reversal if the RBNZ holds interest rates at 5.50% as forecasted. A reversal to the downside could reach the price level of 0.61, supported by the upward trendline, and beyond that, the 0.60 round number key support level.


Todays NFP figure out of the USA is shaping up to be a pivotal moment in market expectations as to whether we’ve seen peak rates from The Federal Reserve, or if there is more to come and the ramifications that will have for the FX market. NFP figures are always interesting, traditionally the biggest market moving figure of the month on the US calendar, and against the backdrop of the Feds “data dependent” messaging regarding future rate moves this figure will be a big piece of how the market prices in the result of the September Fed meeting. Currently markets are butting heads with the Fed, only pricing in a higher chance of no more hikes from the Fed, despite Fed guidance and dot plots indicating they are looking at least one more hike this cycle.
Current September Fed Fund Future odds are showing only a 17.5% of a hike in the September meeting. Source:CME Fedwatch tool Market expectations are for a slowing in payroll growth in July the consensus being 200k nonfarm payrolls to be added to the US economy in July, slightly cooling from the 209k added in June, with the unemployment rate expected to remain unchanged at 3.6%. A big beat or miss on these expectations, a rapid repricing of hike/hold odds would be likely to see volatility and opportunities in FX markets.
Chart to watch: US Dollar Index (DXY) DXY has rallied strongly since mid-July as the UST 10 Year yields pushed higher and getting an extra boost from some risk-off this week in equity markets which pushed DXY through the S/R level at 102. DXY found resistance at its upper trend line at around the 102.84 level, seeing some of the recent gains being pared. Also an important factor is the close relationship between US10 yields and DXY, the yields now above 4% where they have struggled to go any higher in the recent past, this will also see a headwind against DXY pushing higher from this level.
The levels to watch over todays NFP will be 102.84 to the upside on a big beat, 102 as support to the downside if we get a big miss. Both of those levels will be key in the next trend direction of DXY. Calendar:


The Nasdaq Composite Index has kicked off 2023 with a historic performance, achieving its most impressive start since 1975. Despite concerns about a potential recession, the index has displayed remarkable resilience, surging over 37% year-to-date as of the end of July. The upward trend has been consistent, with green months recorded in 6 out of the 7 months of the year so far.
With only 13.50% more to run before it gets back to all time highs set in November 2021, it will be interesting to watch how this plays out over the second half of the year. From a technical standpoint, traders are closely monitoring the current price action within this crucial resistance zone. The market's reaction here will determine its short-term direction.
Will the resistance zone hold strong and push the price downward, or will the momentum be strong enough to break through and continue its journey toward all-time highs? Zooming out to the weekly timeframe, the Relative Strength Index (RSI) has been floating around overbought territory since mid-June. This confluence with the resistance zone indicates a possible cooling off period in the coming weeks.
This scenario wouldn't be overly surprising, as markets often experience a breather after significant surges.


After a fortnight of trending north, Gold has fallen over the past 5 days. It is currently trading at around $1960, showing a slight decline of approximately 1.35% from its recent high of $1987.53. Price is currently trying to break out of the downward channel that it has been in since late last week, so something to keep an eye on going into the key economic data due out this week.
All eyes are now on the upcoming FOMC meeting, where the market is currently pointing towards a high probability (over 98%) of a 25bps rate hike on Wednesday. Considering the historical inverse relationship between gold and the USD, let's explore potential reactions by Gold to the FOMC meeting: Rate Hike Scenario (USD Strengthens): If the FOMC goes ahead with the 25bps rate hike, it could lead to a strengthening of the USD. Higher interest rates tend to attract more investments into the US currency, potentially dampening demand for gold.
Consequently, gold prices might face downward pressure in this scenario. Rate Pause Scenario (USD Weakens): Conversely, if the Fed decides to maintain interest rates at 5.25% or hints at a more dovish approach, the USD could weaken. A weaker USD often prompts investors to seek refuge in gold as a hedge against currency depreciation and inflation.
As a result, gold prices could see an uptick due to increased demand. Source: CME Fedwatch tool With the markets almost entirely pricing in a 25bps hike, unless we get a surprise in the figure, volatility may stay subdued until Fed Chair Jerome Powell begins his press conference shortly after the announcement. Investors and traders will be eagerly analysing his language to see if there are any hints on future movements by the Fed.


The GBJPY has continued to climb strongly to the upside, since the end of March 2023 and currently trades just below the 183.00 price level. This move higher is driven by a combination of the weakness of the Japanese Yen and renewed strength in the British Pound. The Bank of Japan (BoJ) has begun to sound warning bells regarding potentially excessive moves in the Yen, and markets are speculating about the possibility of intervention from the BoJ.
The previous intervention from the BoJ came when the USDJPY reached the 145 price level. The USDJPY currently trades along the 143.60 price level. This could indicate that further upside could be anticipated on the GBPJPY before a strong correction to the downside.
If the GBPJPY breaks above 183 the price could continue to climb towards the next key resistance level of 188.70, with the Ichimoku cloud providing strong support for the uptrend. As the Relative Strength Index (RSI) is well into the overbought region, watch for a possible reversal if the BoJ intervenes, especially along the 188.70 resistance level or at the major swing high of 195.60 (last reached in June 2015)


USD was firmer on Thursday, largely due to a rally in treasury yields with the DXY tracking the 10 year yield higher to a peak of 102.470 after bouncing off the psychological 102 support level. US data was mixed with Unemployment claims and current account figures coming in worse than expected, but this was offset by a beat in Existing home sales. There was a selection of Fed speakers, with the Chair Powell headlining.
Little new was revealed with Chair Powell re-iterating the FOMC broadly feels it will be appropriate to raise rates again this year which surprised no-one. GBP was volatile after the BoE somewhat surprised markets with a larger than expected 50bp hike, going into the meeting a 25bp was the favoured outcome by economists, but a 50bp was partially priced in so not a totally unexpected move from the BoE. The bank also maintained guidance further tightening would be required if there was more evidence of persistent inflation.
Post decision GBPUSD hit a high of 1.2838 in a knee jerk reaction before reversing the move and eventually hitting lows of 1.2728 in similar price action we saw after Wednesdays hotter than expected CPI figure. GBP price action is indicating the market feels further hawkish re-pricing of BoE action is limited, with fears that the current projected path will lead to recession in the UK weighing on the Pound and Cable will struggle to breach the major resistance at 1.28. CHF was lower vs the USD after seeing weakness in the aftermath of the SNB rate decision where the SNB hiked by 25bps disappointing some market participants who were looking for a 50bp move.
The SNB did note however that additional rate hikes will be necessary. After an initial spike lower to test the 0.8900 support zone, USDCH reversed course, hitting a high of 0.8973 before finding some selling. JPY was the G10 underperformer with USDJPY printing a fresh 2023 high of 143.22 after breaching the key 142.50 level, with a CPI report coming up today, another close above this level could see a technical continuance to test the 145 level.
Recent Fed speak has also raised the issue that US treasury yields are likely to continue to rally, increasing the rate differential between US10Y and JGBs which will also be a major tailwind to get the pair to 145, which is where the BoJ's November USDJPY intervention was launched.
