With the ever-increasing demand for high speed and high bandwidth in the era of big data, there is an urgent need for a new type of product as the primary transmission medium for high-performance computing and data centers. Therefore, the development of optical communication transmission rates has also accelerated. Facing the requirements of high speed, high density, low cost, and low power consumption in short-distance data centers for optical interconnect products, 200G AOC active optical cables offer an excellent solution.
Brief Introduction to 200G AOC cables
AOC stands for Active Optical Cable, also known as a powered optical cable. An AOC incorporates electro-optical and photoelectric conversion chips and transmits high-speed signals via optical fiber.
It is an eight-channel, pluggable, parallel, fiber optic QSFP dual-density module for 2x100G Ethernet applications. This optical module is a high-performance module for short-distance, multi-channel data communication and interconnection applications. It integrates eight data channels in each direction with a bandwidth of 8×25.78125Gbps. Each channel can transmit 70m using OM3 fiber or 100m using OM4 fiber. These modules are designed to use a multimode fiber system with a nominal wavelength of 850nm.
Types of 200G AOC cables
With the ever-increasing demand for high-bandwidth, low-latency interconnects in data centers, 200G AOC active optical cable has become the preferred solution for high-speed connections between servers, switches, and storage devices. Depending on different application scenarios and network design requirements, 200G AOC cables can be divided into two categories: cut-through and branch-through, each with its own characteristics in performance and deployment. Understanding the differences between these two types is crucial for rationally planning network architecture, optimizing fiber optic resource utilization, and ensuring equipment compatibility. Below, we will detail the specific applications and features of cut-through and branch-through 200G active fiber cables.
Direct Attach 200G AOC cables
Direct Attach 200G AOC Cables are high-speed, point-to-point active optical cables designed for direct end-to-end connections between devices such as switches, servers, and storage systems. In this straight-through configuration, the 200G signal is transmitted intact without splitting, ensuring maximum bandwidth and minimal latency. Direct attach AOC cables are ideal for spine-leaf and top-of-rack (ToR) network architectures, providing a simple, reliable, and cost-effective solution for short- to medium-distance data center interconnects.
Breakout 200G AOC cables
Breakout 200G AOC active optical cables are designed to split a single 200G port into multiple lower-speed channels, typically converting one 200G interface into 2×100G or 4×50G lanes. This enables a single high-speed switch port to connect to multiple servers or devices simultaneously, optimizing fiber utilization and reducing cabling complexity. Breakout AOC active optical cables are widely used in Top-of-Rack (ToR) deployments and high-density data center environments, providing flexibility for server aggregation, efficient port management, and cost-effective network scaling without sacrificing signal integrity or performance.
200G to 2×100G AOC cables
This breakout 200G AOC cable splits a single 200G port into two 100G lanes. One end connects to a 200G optical module, while the other end connects to two 100G optical modules, supporting a maximum aggregate transmission rate of 212.5Gbps. The 200G module has a power consumption of less than 4W, and each 100G module consumes less than 2.5W. This solution is primarily used in data centers for branching 200G links into two 100G Ethernet connections. By comparison, a standard direct-connect 200G active optical cables maintains 200G connectivity at both ends without splitting.
200G to 4×50G AOC cables
This breakout 200G active fiber cable employs an 8-lane full-duplex active optical design, splitting a single 200G port into four 50G lanes. One end connects to a 200G optical module, while the other end interfaces with four 50G modules, achieving a maximum aggregate transmission rate of 206.25Gbps. The 200G module consumes less than 4W, and each 50G module consumes up to 1.5W. It is widely used in data centers for branching a 200G link into four 50G Ethernet connections, enabling high-density, cost-effective connectivity in Top-of-Rack (ToR) and aggregation scenarios.
Application scenarios of 200G AOC cables
Data Center Interconnects
200G active fiber cables are widely deployed in modern data center environments to support high-bandwidth, low-latency interconnections between switches, servers, storage arrays, and aggregation layers. They are particularly suitable for Spine-Leaf architectures, Top-of-Rack (ToR) deployments, and cross-rack connections within short- to medium-distance ranges. By providing stable 200G transmission with simplified cabling and reduced electromagnetic interference (EMI), AOC cables help improve port density, reduce cable management complexity, and optimize overall network efficiency in high-density data center environments.
High-Performance Computing (HPC)
In high-performance computing clusters, massive volumes of data must be exchanged between compute nodes, GPUs, and storage systems with extremely low latency and high throughput. 200G AOC active optical cables provide reliable short-distance optical transmission that supports fast node-to-node communication and accelerates parallel computing workloads. Their lightweight structure and lower power consumption compared to discrete transceiver solutions make them well-suited for AI training platforms, scientific research clusters, and large-scale simulation systems where bandwidth and stability are critical.
Cloud Computing Infrastructure
Cloud service providers rely on scalable and high-speed network architectures to support virtualization, distributed storage, and large-scale data processing. 200G active fiber cables enable efficient interconnection between server clusters and core switching equipment, ensuring consistent bandwidth availability and low latency across cloud environments. Their plug-and-play design simplifies deployment and maintenance, while supporting flexible expansion as cloud infrastructure grows.
High-Definition Video and Media Transmission
In scenarios such as large-scale video surveillance systems, broadcast production, and real-time media processing, high data throughput and signal stability are essential. 200G AOC cables can support the transmission of high-resolution video streams and large multimedia data sets with minimal signal degradation. Optical transmission also provides strong immunity to electromagnetic interference, making AOC cables suitable for environments requiring stable, high-quality signal delivery.
