Direct Attach Cable | 10G SFP+ DAC Knowledge Sharing

10G SFP+ DAC knowledge sharing

December 11. 2017

In recent years, customers require more and more flexible and scalable I/O solutions to meet the rigorous requirement of different deployments.
10G SFP+ DAC cables meets the demanding needs for today's data center environments.
Moreover, price, performance and flexibility have made 10G SFP+ Cable an attractive choice for the data center.
Today we would like share some knowledge of 10G SFP+ DAC cable with you, hope it would help your business or market sharing enlargement.

1. What's 10G SFP+ DAC Cable?
DAC means Direct Attach Cable.
10G SFP+ DAC Cable is a copper interconnect using an inexpensive Twinax copper cable assembly with SFP+ connectors on both sides based on SFP+ MSA(multi-source agreement).
It has the advantage of low power, low cost and low latency.

2.10G SFP+ DAC Cable type?
10G SFP+ DAC Cable uses a copper 10G cable that comes as active or passive Twinax cable assembly and connects directly into an SFP housing.
10G SFP+ Active Cable have a silicon chip to boost the performance of the cable. Without a chip, the cable is considered a "passive"cable.
DAC Cable shorter than 5 meters are passive and those longer than 5 meters are active.

3.10G SFP+ DAC Cable solution VS SFP+ Optical transceiver solution?
10G SFP+ DAC Cable solution: The distance is less than 15M between two devices, you can choose this solution with competitive price and high speed.
And it save cost, compare with SFP+ optical transceiver solution.
Optical transceiver solution: Considering the substitutability of products, if one side's broken, the other side also can be used, that wouldn't influence your working efficiency so much.

Compare with DAC Cable solution, it's more flexible. If you want increase distance one day, you don't need to purchase Optical transceivers again.
