In DCN&Cloud network, Optical Transceiver doesn't draw much attentions, but no doubt, it an integral and important parts for the whole structure. Whichever data center can not avoid the arrangement of Optical Transceivers, and the quantity usually high. Therefore, it brought up the biggest matter which the service provider concern about, which is Power.
4Fiber offers a range of low power consumption transceivers for green data center application.
10G SFP+ Transceivers
40G SFP+ Transceivers
The Former ISP offers free service for the RJ45 ports on the master board. However, when the 10G ports released, the pluggable transceiver became a fixed cost. In present there are 3 main type of service card in 10G Ethernet DCN server. Which are 10G Base-CR, 10G Base-T and 10G Base-SR. From those 10G Base-CR use SFP+ DAC(Direct Attached Cable), under this structure, 10G SFP+ DAC is the best way to show up the advantage of the cost and low power.
The 40G QSFP+ DAC is the main stream products in next 3 years for 40G transmission. The 40G QSFP+ DAC is capable to converter the 40G port from the switch down side layer to 4 10G Channels to the service ports.
The AOC (Active Optical Cable) has an inimitable advantage compare with DAC at beyond 7 meters length, it is lighter and bigger bend angle.
