40g qsfp+ is the optical module package type is qsfp+ (four-slot small form factor pluggable), that is, a four-bay small pluggable optical module. This type of packaging was created to meet the market demand for higher-density, high-speed pluggable solutions. The whole system consists of a 38PIN connector, electromagnetic interference (EMI), optical transceiver, heat dissipation components, copper cable assembly, MTP optical cable assembly, optical loop, etc.
This optical module is only 30% larger than the standard SFP module. The original design purpose was to replace single-channel SFP with a high-density optical module. Due to the limited space of the device frame panel, the number of fiber optics is limited. If using a standard SFP or 10Gbps XFP connector, the number of channels that can be supported is limited by physical space. Qsfp+ can combine more transponders and receivers in a smaller area
This optical module mainly realizes the connection of 40g high bandwidth fiber optic link over 12 core fiber optic cable with MPO/fiber connector. MTP can also realize 4x10g duplex mode connections by connecting four 10gbase-sr fiber optic cables.
What is meant by optical switching?
The process of controlling the destination of each optical signal through an optical switch is called optical switching. In the process, high bit rate optical signals are switched between different optical cables.
It reduces the congestion encountered in the previous network when optical transmission occurs. Optical switches are more efficient and faster than copper switches. This makes the light switch quicker and more efficient. An optical signal will not be affected due to interference found in EM wave propagation. It provides better security as optical signals travel over fiber optic cables and not through the air. It helps to reduce node size, very flexible network utilization, and very efficient network utilization. They are generally used for a variety of applications such as lighting path arrangements, switching protection, and elements that allow high-speed packet switching networks.
