In the era of big data with rapid growth of business traffic, the development of technology is more and more diversified. Users like high-speed, stable interconnection, high performance and low power consumption. The 56G QSFP+ SR4 optical module is a duplex transceiver module, which has such characteristics. Today, we will introduce this optical module in detail for you.



Product Description:

QSFP-56G-SR4 is a four channels, used for InfiniBand FDR / QDR / DDR / SDR, 16G / 10G / 8G / 4G / 2G fiber channel, PCIe and SAS, hot pluggable. The optical module is a high performance module and interconnection application for short-range multichannel data communication. It integrates four data channels with 56 Gbps bandwidth in each direction. 


These modules are designed to operate on a multimode fiber system with a wavelength of 850nm. 38 contact edge type connector is used for electrical interface. Optical interface uses 12 fiber MTP (MPO) connector.


The module combines the reliable circuit of ETU-Link and VCSEL technology to provide reliable long life, high performance and consistent service. VCSEL and pin array packaging are key technologies, which can be contacted with modules through I2C system. The maximum link length on the OM3 multimode fiber (MMF) is 100m, while the maximum link length on the OM4 MMF is 150m.
