The Technical Background of 40G QSFP + Optical Transceiver

With the advent of the age of cloud computing and big data, the network is being forced to develop at a high rate and density, and the utilization of virtualized servers is increasing. In order to provide sufficient I / O (input / output) bandwidth, many new access switches have been developed to 2 or 4-port 40G Ethernet that can connect to core switches. The rapid development of interconnected data transmission is inseparable from the 40G QSFP + optical Transceiver, because it can provide sufficient bandwidth to ensure unhindered data conversion, thereby meeting the network requirements of data centers and enterprise campuses.

Factors to Consider When Choosing 40G QSFP+ Optical Transceiver

When choosing a 40G QSFP+ optical transceiver, there are several important factors to consider. These factors will help ensure compatibility, reliability, and optimal performance within your network environment. Here are some key considerations:

Transmission Distance: Different 40G QSFP+ optical transceiver support varying transmission ranges, such as short-range (SR) for up to 100 meters, long-range (LR) for up to 10 kilometers, or extended range (ER) for up to 40 kilometers.

Fiber Type: 40G QSFP+ optical transceiver are available for both multimode fiber (MMF) and single mode fiber (SMF). MMF is typically used for shorter distances within data centers, while SMF is suited for longer distances over larger network infrastructures.

Compatibility: Ensure compatibility with your networking equipment, such as switches, routers, or servers to guarantee seamless integration with your existing infrastructure.
