The active cable AOC active fiber optic cable, with the cable also called chip. Traditional data center interconnect is mainly based on a number of significant advantages over coaxial cable, AOC active optical cable and copper interconnect compared to ownership. Such as lower transmission power on the system link, direct copper weighs only a quarter of a volume of about half the copper, and has a better air flow heat dissipation in the wiring system in the engine room, the cable bend made smaller than the radius off copper, over longer distances (up to 100 to 300 meters), and the transmission error rate performance of the product is also more preferably, the BER can be up to 10 ^ -15. Compared with the optical transceiver module, AOC active optical cable due to the presence of the interface is not exposed to light, the optical interface clean and there is no problem of contamination, greatly enhance the stability and reliability, and reduce maintenance costs of the equipment room.
Optical Engine active cable products are the best solution for high-speed data based optical interconnection, an interconnect structure is between a chip. The current market mainstream products include high-speed optical interconnection AOC 10G SFP + AOC, 40GQSFP + AOC, 56G QSFP + AOC and 120G CXPAOC and so on.
What is the 40G QSFP + AOC active optical cable?
40G QSFP + AOC is the core active optical cable parallel optical interconnection member is connected by a high speed ribbon fiber jumpers 40G two parallel connectors, each direction signal has four data channels, each channel can operate at the speed of 10Gbps, transmission distance of 1 to 100m, for the ends of the splitter cable length can be freely selected.
Compared with the traditional copper 40G, 40G the AOC active optical cable comprising at least 7 meters incomparable advantages data transmission environments, such as those having incomparable advantages: high transmission efficiency, small size, light weight, low energy consumption; the AOC and the optical module failure than when the connector is not cleanliness problems, without the need for a terminal plug test can help save more time; the AOC wirings better consistency and reproducibility, closed at both ends is easier to avoid environmental the effects of vibration and swing, if the failure can be directly replaced, cost savings; AOC advantage relative to the optical module price is much cheaper, can save the cost of deployment, and the transmission distance also meet a variety of short-distance transport applications.
40G QSFP + AOC application
High-speed optical interconnects 40GQSFP + AOC and 120G CXP AOC not adopted design TOSA / ROSA conventional pluggable transceivers, and the use of highly integrated device technology core array of light engines. Integration mode - a small package, high speed, low power consumption (QSFP + power consumption is less than 1.5W, CXP consumes less than 2.5W). On the transmit side, an array of the optical engine simultaneously processing a plurality of high speed electrical channels, converts it into multi-channel optical signals, and then combining the optical signals, (the core 24) of MPO high density by an optical cable 12 are transferred to the core information next node cloud computing system or data center room. At the receiving end, an array of optical engines convert the optical signals back to electrical signals in the cable MPO, processing the electrical signal to the multiplexing device. These products are fully applicable to the interconnection scenarios, while meeting the Ethernet IEEE 802.3ba. In the data center, and fIELD cloud computing system, an array of optical engine technology has been widely applied to an active optical cables - the interconnection between the server and the switch.
