UnitekFiber 40G QSFP+ PSM AOC active optical cable, the optical port side adopts PSM (Parallel Single Mode) parallel single-mode technology with 8 single-mode fibers, and uses 4 parallel MPO/MTP interfaces to achieve effective transmission of 2 kilometers.
The 10-meter 40G QSFP+ to 4x10G SFP+ Breakout Active Optical Cable (AOC) is an extended-reach interconnect solution designed for high-density data centers. It splits a single 40G QSFP+ port into four 10G SFP+ ports over a 10m OM3/OM4 multimode fiber link. Unlike copper DACs, which struggle with signal degradation at 10m, this AOC ensures zero-error transmission and significantly easier cable management due to its thin, flexible 3.0mm LSZH jacket.

For 10m deployments, the weight of the cable and the power budget of the switch ports become critical factors.
| Feature | 40G Breakout AOC (10m) | 40G Breakout DAC (Copper) |
| Reach Capacity | Up to 100m (Stable) | Max 7m (Unreliable at 10m) |
| Cable Diameter | 3.0mm (Round Fiber) | ~10.0mm (Twinax Copper) |
| Bending Radius | 30mm (Highly Flexible) | >100mm (Very Stiff) |
| Weight | ~0.2kg (Lightweight) | ~1.5kg (Heavy Strain on Ports) |
| Latency | Low Latency (Light Speed) | High Latency (Electrical Skin Effect) |
At 10 meters, passive copper cables suffer from significant Insertion Loss and Inter-Symbol Interference (ISI). Our AOC utilizes internal CDR (Clock and Data Recovery) technology at both the QSFP+ and SFP+ ends. This actively reshapes the electrical signal, ensuring that even at the end of the 10m fiber, the "Eye Diagram" remains wide open, meeting the strict IEEE 802.3ba standards.
Data center cooling costs are tied to transceiver power. Our 10m AOC is engineered for ultra-low power consumption:
QSFP+ End: < 1.5W
SFP+ End: < 1.0W
This results in a total link power saving of approximately $30\%$ compared to using discrete 40G SR4 and 10G SR transceivers with separate patch cords.
When scaling to 10 meters and beyond, mechanical stress on switch ports is a hidden killer. A 10m copper breakout cable can weigh over 1kg, pulling down on the SFP+ cage and causing intermittent physical layer errors. Our 10m AOC is 80% lighter, preserving the structural integrity of your high-end switch hardware

This 10m breakout AOC is the perfect fit for Top-of-Rack (ToR) to End-of-Row (EoR) architectures where servers are distributed across multiple cabinets. It simplifies the transition from 40G core layers to 10G access layers without the complexity of fiber cleaning and transceiver matching.
Don't let bulky cables choke your airflow. UnitekFiber provides factory-tested, high-reliability AOCs with a 3-year warranty and global shipping.

Active Optical Cables (AOC) are optical fiber cables with fiber optic transceivers installed at both ends. The main components are divided into two parts: optical circuit and circuit.
Yes. As a main transmission medium for high-performance computers and data centers, active optical cables(AOC) ensure the stability of transportation and flexibility of application, and are more common in high-density applications.
Passive 40G DACs are technically limited to 7 meters. At 10m, only an Active Optical Cable (AOC) can provide the necessary bandwidth without massive signal loss or excessive cable bulk.
Yes. We provide dual-vendor coding services. We can code the 40G side for Cisco and the 10G breakout sides for Mellanox or generic servers to ensure 100% interoperability.
In laboratories and teaching centers, (AOC) active optical cables connect multiple machines to the host, which not only ensures high-speed data transmission but also ensures network security.
Both data centers and cloud computing systems require higher bandwidth and lower power. 10G SFP+ in AOC (active optical cables) can well connect devices (switches, routers) with high-speed optical communication ports.
Digital signage is a good place for AOC active optical cables to show their talents, which can support 1080p resolution in an outdoor HDMI environment.
AOC(Active optical) cables are more and more widely used in high-density data centers due to the advantages of long transmission distance, fast transmission rate and convenient use. UnitekFiber supplies various types of active optical cables with high stability and reliability.
Pulling this through ceilings and in conduit - this is fantastic cable. Flexible doesn't hold shape. Very nice to crimp as well.
