Active optical cables (AOC)
Leading suppliers of active optical cables
Active optical cables, or AOC as they are commonly called, are a cabling technology used for interconnect in the data centre. AOC accept the same electrical inputs as a traditional copper cable, but instead consist of either single mode or multi-mode fibre. They also have optical transceivers integrated at each end plus a control chip (the active element) to convert electrical signals into optical signals that can be carried over the optical fibre.
What are the advantages of AOC over DAC?
AOC are popular because they have overcome the limitations associated with Direct Attach Cables (DAC) and passive cabling:
- AOC weigh less than DAC; copper cables are bulky, heavy and therefore more difficult to manage
- AOC have better performance than DAC; electromagnetic interference (EMI) ultimately limits the performance of copper cables
- AOC consume less power than DAC
- AOC have less interconnection loss, compared to DAC
The main types of AOC we provide
We offer an extensive range of active optical cables for interconnect in the data centre. Our active optical cables are compatible with a wide range of data centre device manufacturers and the interconnection meets MSA (multi-source agreement) standards.
- 10G SFP+ to SFP+ AOC
- 40G QSFP+ to 4 x SFP+ AOC
- 40G QSFP+ to QSFP+ AOC
- 40G QSFP+ to 8 x LC AOC
In the case of a typical 40 Gb/s QSFP+ AOC, we support the following protocols
- Multi-rate (1Gb/s to 10 Gb/s)
- 4 channel full duplex AOC transceiver
- InfiniBand (registered trademark of InfiniBand)
- Ethernet 10G, 40G
