DAC

Direct Cable (DAC) is a Direct Cable or copper Cable. It refers to installing light modules at both ends of high-speed jumper. By connecting switch to router or server, it is widely used in storage area network, data center and high-performance computer connection, which is rising gradually in network communication.

The advantages of high-speed cable DAC are as follows:

1. High performance: suitable for short distance wiring of data center, wide range of use, strong exchange ability of integration scheme.

2. Energy saving and environmental protection: The internal material of the high-speed cable is copper core. The copper cable has good natural heat dissipation effect and energy saving and environmental protection.

3. Low power consumption: low power consumption of high-speed cable. Since the passive cable does not need power, the power consumption is almost 0. The power consumption of active cables is generally around 440mW.

4. Low cost: Copper cables are much cheaper than fiber, so using high-speed cables can greatly reduce the wiring costs of the entire data center.

AOC

AOC Active Cables are communication Cables out of which electrical signals are converted into Optical signals or into electrical signals with the help of external energy during communication. Optical transceivers at both ends of the Cables provide Optical conversion and Optical transmission functions

QSFP + AOC active optical fiber for short, is a multiple channel data communication and interconnect application design by the efficient integrated cable assembly products, each signal direction has four data channels, in a single module in 40 GBPS bandwidth sum, each channel can work at 10 GBPS speed, communication distance from 1 to 100 m, is suitable for super computer and based on SDR, DDR and QDR InfiniBand standard applications. QSFP+AOC is the core component to realize parallel optical interconnection. It is composed of two high-speed 40G parallel optical modules connected by ribbon OM3 optical cable (with four 850nm VCSEL transmitting channels and four PIN receiving channels, both at a rate of 10Gbps).
