According to CIR (CommunicationsIndustryResearchers) latest report, "2015 Active Optical Cable Market: data centers and high-performance computing market," in 2020 for the data center of the active optical cable (AOC) market will reach $ 4.2 billion.

(1) Light transmitter
Light transmitter is to achieve electrical / optical conversion of Optical. It consists of a light source, driver and modulator. Its function is to electrical signals from the electrical end machine for light emitted from the light source is modulated, become modulated light, and then the modulated optical signal is coupled into an optical fiber or optical cable to transmit. Electric end machine is conventional electronic communication devices.

QSFP is from a simple single-mode fiber SONET applications out into other multimode fiber applications, such as Gbps Ethernet, Fibre Channel, InfiniBand and so on. Many MSA members of the supply VCSEL chip, parallel VCSEL chips, pushing the QSFP technology in the field of multi-mode.

Optical communication is the physical basis of the entire Internet economy. The beginning of the century, the Internet bubble crisis, the optical communication industry closely related also suffered heavy losses, optical communications giant great loss of strength, Nortel, Lucent since almost brought to its knees. That time foreign optical communications giants are mostly vertically integrated development model, from device to device chips are able to completely independent research and design. After the bubble crisis, in order to preserve the core competitiveness, equipment manufacturers have stripped optical components businesses to form an independent company, or sold to independent manufacturers of optical devices, optical fiber business has been stripped. Optical Communication born light system equipment - fiber-optic cable - optical devices - optical chips complete industrial ecology.
