DACs – Pros and Cons
DACs are heavier and more rigid than AOCs. Also, since higher data rates and longer reaches require thicker copper gauge, the cables become heavier and bulkier as you go up from 40G to say, 400G. So, the reach limit for a 400G DAC is typically 2m, beyond which AOCs are recommended. Fiber management becomes a nightmare at long reaches. DACs have the benefit of being economical and their power consumption is negligible.
AOCs – Pros and Cons
Why Optical Transceivers?
There are use cases in which neither AOCs or DACs are suitable. Pre-terminated DACs and AOCs are not suitable for applications where they need to be pulled through cable trays. These are situations for transceivers. Network upgrades are also easier with stand-alone optical transceivers.
Conclusion
AOCs and DACs are both widely deployed in data centers. DAC is cost-effective, offers low power consumption and is very effective at short reaches. AOCs are preferred for longer reaches. Vitex range of AOCs and DACs are available in various configurations including breakouts. Contact us at sales@vitextech.com for pricing and availability.
