PoE Lighting Integrator
A TALE OF TWO CABLES: ACTIVE OPTICAL CABLES (AOC) VS DIRECT ATTACH CABLES (DAC)
As Data Center and Enterprise usage increases, PoE Lighting Integrators are finding a greater need for high performance, cost-effective network cabling. So, it’s not surprising that Direct Attach Cables (DAC) and Active Optical Cables (AOC) are growing in popularity.
Both cables are plug and play and available in a variety of configurations. As well as being:
- Available on demand
- Coded and triple-tested by a team of optics experts and high-speed robots
- 100% interoperable across all OEM platforms.
But as a Smart Building Integrator, which cable is right for your project? Let’s consider some key factors that will help you determine the right choice to make.
Direct Attach Cables
DAC’s contain a passive component and are used to connect one mobility access switch with another when forming a stack. DAC’s also provide a direct electrical connection between corresponding cable ends and have enough data rate for various applications that support higher data rates than a traditional copper interface.
Power Consumption: Is power consumption a consideration? DAC’s cooling requirements are not strict due to their thermal design, which lowers power consumption and decreases data center operating expenses.
Budget: What is your budget for time and materials? What is your timeline? When implemented in a large data center, DAC’s can significantly reduce costs over same length AOC’s
Wider Operating Temperature: DACs don’t produce heat, making it a more versatile product that can be used in wider temperature ranges
Reliability and Faster Transmission: The mean time between failures (MTBF) is about 500 million hours making them reliable with fast transmission. This MTBF makes DACs essential for data centers.
ACTIVE OPTICAL CABLES
AOC’s are lightweight in design and just like DACs, are widely applied in storage area networks, data centers and high-performance computing connectivity’s. AOC’s use light signals and are not able to conduct an electric current, making them immune to electromagnetic interference.
Cable Management? How much space is available in rack and cable pathways for cabling? The cables of AOCs are thin and have a significant bend radius, making AOCs the optimal solution for Data Centers without enough space for cabling
Greater Bandwidth: Without any equipment upgrades, AOCs have a throughput of up to 40Gbps with QSFP+
Air flow and Cooling: Due to AOC’s cable being thin in design, the cooling efficiency and lifetime of the connected equipment will benefit significantly
As a smart building integrator, whichever option you choose, when coupled with Legrand’s transceivers, powered by Integra, you have the best combination in the industry. Interested in the AOC and DAC cables? Contact C&C Tech Group today for more information!
