Optech Built for AI: High-Speed Connectivity for Next-Generation AI Infrastructure

AI is transforming the way networks operate—and your infrastructure needs to keep up.

As artificial intelligence moves from individual servers to large-scale GPU clusters, the network has become a critical part of overall AI performance.

Modern AI infrastructure must move enormous amounts of data between GPUs, servers, switches, storage systems, and data center fabrics. Higher bandwidth alone is no longer enough. Networks also need scalability, stability, low latency, flexible connectivity, and a clear upgrade path toward 800G, 1.6T, and beyond.

For Taiwan manufacturer Optech, this is the foundation of Built for AI.

Optech Built for AI solutions deliver the high-performance connectivity, speed, and scalability required for next-generation AI, HPC, cloud, and data center environments.

From high-speed optical transceivers to DAC, AOC, AEC, breakout cables, liquid-cooling interconnects, and customized connectivity solutions, Optech helps customers build AI infrastructure designed to keep data moving.

Why AI Is Changing Data Center Networking

Traditional enterprise traffic was often dominated by north-south communication between users, applications, and data centers.

AI introduces a very different traffic pattern.

Large GPU clusters generate massive amounts of east-west traffic as processors continuously exchange model parameters, gradients, training data, and synchronization information.

As cluster size increases, network requirements become more demanding.

AI infrastructure increasingly requires:

• 400G, 800G, and 1.6T connectivity
• high-bandwidth GPU interconnects
• low-latency network fabrics
• high port density
• predictable link performance
• scalable leaf-spine architectures
• high-speed server-to-switch connections
• efficient short- and long-reach connectivity
• Ethernet and InfiniBand support
• advanced cooling and high-density deployment

The network is no longer simply supporting AI.

The network is part of the AI system itself.

Built for AI Means More Than Faster Optics

An AI network includes many different types of connections.

Some links are only one or two meters long.

Others may extend hundreds of meters or several kilometers.

Some require optical transceivers.

Others are better served by DAC, AEC, or AOC.

A large AI data center therefore needs a complete connectivity portfolio rather than a single transceiver type.

This is where Optech's broad product offering becomes valuable.

Optech High-Speed Optical Transceivers for AI Networks

High-speed pluggable optical transceivers form the backbone of modern AI networking.

Optech provides optical solutions across multiple network generations, including:

100G → 200G → 400G → 800G → 1.6T

These products can support applications such as:

• GPU cluster networking
• switch-to-switch links
• leaf-to-spine connections
• spine-to-super-spine networks
• cloud data center fabrics
• HPC systems
• storage networks
• data center interconnects

400G Optical Transceivers

400G remains widely used in current AI and data center infrastructure.

Optech can provide multiple 400G architectures depending on reach, connector type, and platform requirements.

Typical applications include:

• AI server connectivity
• network aggregation
• leaf-spine fabrics
• storage networks
• cloud infrastructure

800G Optical Transceivers

800G has become a key connectivity speed for high-performance AI networking.

Optech provides 800G solutions in form factors such as:

with optical options designed for different reach and cabling requirements.

800G is particularly relevant for:

• GPU scale-out fabrics
• AI Ethernet networks
• InfiniBand networks
• high-density switch interconnects
• cloud and hyperscale data centers

1.6T Optical Transceivers

As next-generation AI systems move toward 200G-per-lane SerDes, 1.6T optical connectivity is becoming increasingly important.

Optech's 1.6T portfolio is designed for high-density AI and HPC architectures requiring extremely high aggregate bandwidth.

Examples include:

• 1.6T OSFP224 DR8 / 2xDR4
• 1.6T OSFP224 2xFR4
• next-generation AI switch fabrics
• InfiniBand XDR environments
• GPU cluster scale-out networks

These products give customers a migration path beyond 800G.

DAC: Low-Power Short-Reach AI Connectivity

For very short network connections, optical modules are not always the most efficient choice.

DAC — Direct Attach Copper can provide low-power, low-latency connectivity between nearby equipment.

Typical applications include:

• server to switch
• NIC to switch
• DPU to switch
• switch to switch
• same-rack AI connections

Optech provides multiple DAC architectures, including high-speed and breakout configurations.

For dense AI racks, DAC can offer several advantages:

• lower power consumption
• simple plug-and-play installation
• lower cost
• low latency
• fewer components

AOC: Lightweight High-Speed Optical Cabling

When the required distance exceeds practical passive copper reach, AOC — Active Optical Cable provides another useful option.

AOC integrates optical engines and fiber into a pre-terminated cable assembly.

Compared with high-speed copper cables, AOC can provide:

• longer transmission distance
• lighter cabling
• easier cable routing
• reduced electromagnetic interference
• high bandwidth
• simple installation

AOC can be especially useful for:

• rack-to-rack AI connectivity
• GPU cluster fabrics
• HPC systems
• high-density cloud environments

AEC and Active Copper for AI Infrastructure

As speeds increase, passive copper reach becomes increasingly limited.

AEC — Active Electrical Cable can extend electrical connectivity beyond passive DAC distance while maintaining a copper-based architecture.

AEC can be useful for:

• high-speed server connections
• AI rack interconnects
• short-reach switch connections
• dense GPU systems

Optech can work with customers to select the appropriate interconnect architecture based on distance, power, cable density, and platform requirements.

Breakout and Fanout Solutions for High-Density AI Networks

AI switches often provide very high-speed ports that need to connect to multiple lower-speed endpoints.

For example, one high-capacity switch port may need to break out into multiple server or NIC connections.

Optech can support customized breakout and fanout architectures such as:

• OSFP to multiple QSFP interfaces
• QSFP-DD breakout
• QSFP112 breakout
• custom lane mapping
• mixed-speed connections
• application-specific cable lengths

Breakout solutions can help improve switch port utilization and simplify AI network topology.

Built for Ethernet and InfiniBand AI Fabrics

Modern AI infrastructure can use either Ethernet or InfiniBand networking.

Both architectures require extremely high bandwidth, but compatibility requirements may differ in areas such as:

• EEPROM coding
• firmware
• FEC
• lane mapping
• port breakout
• management interfaces
• host configuration

Optech can provide platform-oriented configuration and compatibility support based on the customer's target environment.

Customers can provide:

• switch model
• NIC or DPU model
• firmware version
• Ethernet or InfiniBand
• required speed
• optical reach
• connector requirement

and Optech can help identify an appropriate product configuration.

Supporting NVIDIA and Other AI Networking Platforms

Modern AI infrastructure is increasingly built around advanced GPU, NIC, DPU, and switching platforms.

Optech's compatibility strategy focuses on supporting major networking ecosystems through:

• EEPROM coding
• platform qualification
• link testing
• digital diagnostics
• optical power testing
• FEC verification
• firmware matching
• application-specific configuration

For NVIDIA-oriented AI networks, Optech has solutions covering multiple generations of high-speed optical connectivity for environments using high-speed OSFP, QSFP-DD, QSFP112, and OSFP224 interfaces.

Compatibility should always be confirmed against the actual host platform and firmware configuration before volume deployment.

Built for AI Cooling: Immersion and Liquid-Cooled Connectivity

AI servers and switches continue increasing in power density.

As a result, advanced liquid cooling and immersion cooling are becoming increasingly relevant to next-generation AI data centers.

Optech can support connectivity requirements for immersion environments, including:

• immersion-oriented optical transceivers
• Immersion DAC
• Immersion AOC
• high-speed copper solutions
• customized cable materials
• customized cable lengths
• QSFP / QSFP-DD Immersion Extenders

One particularly useful architecture is the Immersion Extender, which allows the high-power switch to remain inside the cooling liquid while moving the actual optical transceiver to an external dry environment.

This can simplify:

• optical transceiver replacement
• fiber connector maintenance
• transceiver compatibility changes
• material compatibility management

It also gives customers more flexibility when designing liquid-cooled AI infrastructure.

Different AI Links Need Different Connectivity Technologies

There is no single best interconnect for every AI network link.

A practical AI infrastructure may use several technologies simultaneously.

The ideal architecture depends on distance, bandwidth, power, topology, cooling design, and existing cabling.
