In the automated workshop of Zhejiang Zhaolong Interconnect, a high-speed chip mounter is assembling indium phosphide laser chips on a ceramic base with an accuracy of 0.02 mm. These precision components are about to become the core of 10G optical modules that support the modern digital world. As an "evergreen" in the field of optical communications, 10G optical modules still maintain amazing market resilience in the siege of 25G/400G high-speed modules - with a global annual shipment of more than 30 million units, they continue to expand in emerging fields such as 5G fronthaul and industrial Internet. This article will penetrate the surface and decode the survival rules of 10G optical modules in technological evolution, market competition and future changes.
The core battlefield of 10G optical modules unfolds in the quantum well structure of 1570nm wavelength. The transmitting component adopts EML (electroabsorption modulated laser) technology, and realizes 10.3125Gbps linear modulation through quantum confined Stark effect. Its key indicator is -20dBm receiving sensitivity, which means accurately identifying the signal among tens of billions of photons per second, which is equivalent to capturing the trajectory of specific raindrops in a typhoon.
GaAs-based APD avalanche diode achieves -28dBm sensitivity breakthrough
The third-order eye compensation algorithm controls TDECQ (transmission dispersion eye closure cost) within 1.5dB
The 0.1°C precision TEC temperature control system ensures wavelength drift <±0.08nm
Under the IEEE 802.3ae standard framework, the protocol implementation of 10G optical module hides mysteries:

# Typical CDR (clock data recovery) algorithm pseudo code def adaptive_cdr(signal):
phase_error = calculate_phase_difference(signal, local_clock)
loop_filter = IIRFilter(coeff=[0.8, 0.2])
vco_adjust = loop_filter.process(phase_error)
return recover_clock(vco_adjust)
This digital phase-locked loop design can control the clock jitter within 0.15UI, ensuring a bit error rate of 10^-12 under the FR (Fibre Channel) protocol.
Application scenario | Market share | Annual growth rate | Main players |
5G fronthaul | 32% | 18% | Hisense Broadband, Optical Fiber Technology |
Industrial PON | 25% | 25% | Zhaolong Interconnect, Huawei |
Enterprise network upgrade | 28% | 12% | Cisco, Arista |
Video surveillance | 15% | 8% | Dahua, Hikvision |
Silicon photonics technology reduces BOM cost by 40%
Automated mounting process increases production cycle to 8 seconds/module
Third-generation COB (chip on board) packaging technology saves 30% space
Japan's Sumitomo's indium phosphide substrate, the United States' II-VI's TEC chip, Taiwan's Lian Ya's grating array - the global supply chain of 10G optical modules is undergoing geopolitical reconstruction. In 2022, Zhaolong Interconnect will realize the localization of DFB laser chips, with a yield rate exceeding 85%, which directly leads to the price curve of 10G SFP+ modules dropping to the critical point of US$35.
Under the Open RAN architecture, the 10G optical module uses the innovative eCPRI compression algorithm to achieve the following in the 7/13GHz frequency band:
Delay <100μs
Time synchronization accuracy ±10ns
Support 256QAM modulation
China Mobile's live network test shows that the deployment cost of AAU (active antenna unit) using enhanced 10G modules is reduced by 23%.
In Baosteel's smart workshop, 10G optical modules are undergoing severe tests:
-40℃~85℃ wide temperature operation
50g vibration and shock resistance
10-year MTBF (mean time between failures)
Through ceramic sealing packaging and military-grade connector design, the module still maintains 0 packet loss rate in the dust concentration of 200mg/m³ in the foundry.
Intel's 100G silicon photonic module production line is reversely penetrating the 10G market, and its monolithic integration technology can reduce the size of 10G modules by 60%. However, traditional manufacturers use 3D heterogeneous packaging technology to achieve 25G compatibility while maintaining the cost advantage of 10G.
The experiment of USTC shows that after quantum enhancement transformation, 10G optical modules:
The security key rate is increased to 1Mbps
The transmission distance is extended to 150km
This "classical-quantum" hybrid architecture may rewrite the technical roadmap of optical modules.
The latest "Energy Efficiency Act for Optical Network Equipment" issued by the European Union requires that the energy efficiency ratio of 10G modules reach 0.15W/Gbps in 2025. This drives:
The application of aluminum nitride heat dissipation substrate
Adaptive power regulation algorithm
Photonic crystal waveguide technology
Alcatel's laboratory samples have achieved a breakthrough of 0.12W/Gbps.
While the industry is still debating whether 10G optical modules belong to "traditional technology", engineers at Zhejiang Zhaolong Interconnect are debugging the world's first 10G/25G adaptive production line - this technical flexibility may be the password for the continued prosperity of 10G optical modules for 20 years. In the long history of the evolution of optical communications, the 10G module is neither the starting point nor the end point, but it teaches us that the true value of technology lies not in the numbers on the transmission rate table, but in how to transform physical limits into commercial art.
For practitioners, the 10G optical module is like a prism: through it, we can see the exquisiteness of basic optoelectronic devices, reflect the essence of market demand, and glimpse the future spectrum of technical routes. In this era where bits and photons dance together, perhaps we should rethink: When we talk about 10G, what are we protecting? And what are we subverting?
