200G QSFP56 modules are widely used in Mellanox, Intel Network cards, Arista, Huawei Data Center switches and other industry well known manufacturers equipment. 200G QSFP56 transceiver can work in 80% of networking equipment, where there is no special algorithm for protection. Optical modules are optoelectronic devices that perform photoelectric and electro-optic conversions. The optical signals back into electrical signals. Optical modules are classified by their packaging forms, with common types including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP56, QSFP112, and. GND is the symbol for signal and supply (power) common for the QSFP56 module. SR4 and FR4 options supporting 100m to 2km reach While 100G transceivers (especially QSFP28 form factor ones) are well known and used on a large scale in the optical industry, the demand for higher capacity. The 200G transceiver represents a critical advancement in high-speed optical connectivity, delivering the performance and efficiency needed for modern data centers, cloud networks, and 5G infrastructure. The electrical interface to the module contains 4 independent electrical input/output channels each operating at 53. 125Gb/s and based on 200G CAUI-4 in. SULITON has the ability to provide OEM and ODM of dozens of optical modules from 1G to 800G at a price that satisfies you. It is compatible with most switches(CISCO, Huawei, etc) Compared to existing QSFP28, it has fewer optical components, excellent power consumption, and cost performance.
