Optical module types include 1 × 9, SFF, SFP, GBIC, XENPAK, XFP, SFP+ and 10G optical modules above.

Since its inception in 2007 AOC come out, the market has been volatile. Service has always been the mainstream of high-performance computer market 4x10Gbps QSFP+ AOCs is the case. Thankfully, the data center servers using 10GbE SFP+ AOCs. Accounting for a quarter of $ 87 million in 2014 AOC market. Data centers also require higher speed Ethernet: 25G, 40G, 100G, or 400G. The connection between the needs of the core router chassis AOC. This makes the AOC market in 2020 grew to $ 193 million.

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.

Fiber optic transceivers may be in a response network traffic surge center of attention, but the link platform, panel-board equipment and other functions is the supplier of fiber optic transceivers can achieve product differentiation play space.

QSFP (Quad Small Form-factor Pluggable): Quad-SFP interfaces (QSFP), QSFP is to meet the market demand for higher-density, high-speed pluggable solutions born.
