Active Optical Cable (AOC) is an integrated fiber-optic assembly that combines high-speed transceivers with fixed optical cabling. Designed for AI supercomputing, InfiniBand, and Data Center Interconnect (DCI) scenarios, AOCs eliminate the risk of optical port contamination and signal loss associated with traditional patch cords. Unitekfiber, a premier AOC manufacturer, offers customized 25G, 40G, 100G and 400G AOC solutions, providing a low-latency, "plug-and-play" alternative to discrete transceiver-and-jumper combinations.
Active optical cable (AOC) can be defined as an optical fiber jumper cable terminated with optical transceivers on both ends. Unlike traditional copper cables, which rely on electrical signals for data transmission, AOC cable utilize optical fibers to transmit data using light signals. These optical fibers are integrated into the optical cable assembly along with active components such as laser diodes, photodiodes, and control circuitry. The active components convert electrical signals into optical signals for transmission and then back to electrical signals at the receiving end. AOC is designed to provide a reliable and efficient solution for high-bandwidth connectivity in various applications, including data centers, networking infrastructure, and consumer electronics.
In the era of massive data throughput, AOC fiber cables have become the mainstream application for short-reach high-density cabling. By factory-terminating the optical modules directly onto the fiber, Unitekfiber ensures superior signal integrity and EMI immunity.
High-Speed Trunk AOCs: Available in 25G SFP28, 40G QSFP+, and 100G QSFP28 for point-to-point server-to-switch links.
Breakout AOC Solutions: Specialized 40G to 4×10G and 100G to 4×25G breakout cables, ideal for high-density port migration and bandwidth distribution.
Customized Lengths & Compatibility: We provide tailored lengths and multi-vendor EEPROM coding (Cisco, Arista, Mellanox compatible) to fit your specific rack architecture.
AOC active optical cable comes in various form factors, such as SFP+, SFP28, QSFP+, QSFP28 and HDMI. UnitekFiber offers a series of customized AOC cable, such as AOC trunk cable, and Breakout AOC cable. These form factors cater to different connectivity requirements and are widely used in applications such as high-speed data networking, storage area networks (SANs), video streaming, and computer-to-monitor connections.

Traditional data center interconnection is mainly based on coaxial cables. AOC fiber cables have many significant advantages over interconnected copper cables. For example, the transmission power on the system link is lower, the weight is only a quarter of the directly connected copper cable, the volume is about half that of the copper cable, and it has better air flow and heat dissipation in the wiring system of the computer room. The fold radius is smaller than that of copper cables, and the transmission distance is longer (100 to 300 meters). The bit error rate of the product transmission performance is also better. Compared with the optical transceiver module, the AOC active optical cable has no exposed optical interface, does not need to consider the problems of pollution on the optical interface. Thus, it greatly improves system stability and reliability, and reduces maintenance costs in the equipment room.

Difference Between Active Optical Cable vs Optical Transceiver
A 100G QSFP28 Active Optical Cable is a factory-integrated assembly that replaces two 100G transceivers and a fiber patch cord. The primary benefits include higher reliability (no exposed optical connectors to clean), lower power consumption (often <2.5W per end), and lower latency. It is the most cost-effective solution for short-reach (up to 70m-100m) Leaf-Spine interconnections.
10G SFP+ Active Optical Cables are generally dedicated to 10G ports. For 40G QSFP+ Active Optical Cables, they are primarily designed for 40G-to-40G links. However, Unitekfiber also provides 40G QSFP+ to 4x10G SFP+ breakout AOCs, which allow a single 40G port to connect to four 10G ports, effectively facilitating bandwidth migration in legacy-to-modern network upgrades.
In AI supercomputing and InfiniBand EDR environments, low latency and massive throughput are mandatory. The QSFP28 Active Optical Cable provides a stable 100Gbps link with integrated optics that minimize the signal jitter often found in modular transceiver-and-jumper setups. At Unitekfiber, our QSFP28 AOCs are tested for 100% compatibility with high-performance NICs (like Mellanox) to ensure zero-packet-loss performance.
Yes. A 100G QSFP28 Active Optical Cable is a factory-integrated assembly that functions as a permanent link between two ports. By eliminating the need for separate 100G QSFP28 transceivers and a fiber patch cord, you remove the risk of optical port con
