As the scale of the 100G industry expands and the speed of optical communication data centers advances, it is an inevitable trend that the cost of 100G optical modules will correspondingly decrease, thereby reducing the overall deployment cost of 100G networks.The 100G QSFP28 optical module first appeared in 2013. After several years of development, the 100G QSFP28 optical module has spawned multi

This article briefly introduces the application scenarios of QSFP-DD in data centers—mid-range transmission.QSFP-DD Mid-Range Optical ModulesThere are various types of QSFP-DD optical modules for 2km-10km transmission.The main focus is on four models: FR4/FR8 (2km) and LR4/LR8 (10km).QSFP-DD FR4 Optical ModuleThe "FR" in QSFP-DD FR4 optical module denotes a transmission distance of 2km.

The 200G QSFP-DD PSM8 utilizes NRZ encoding rules and employs parallel single-mode 8 lanes, also known as parallel single-mode technology, in its optical module. Whether it's a 40G, 100G, or 200G optical module, the cost advantage of PSM technology over wavelength division multiplexing technology is evident.The application of 200G optical modules in data centers raises the bar for manufacturer

Switches come in three types: those with only electrical ports, those with only optical ports, and those with a mix of both electrical and optical ports. There are two main port types: optical and electrical. The following information outlines the differences between switch optical ports and electrical ports, compiled by Walsun.Optical ports on switches typically require the insertion of optical m

Concepts Simplex: Data transmission supports data transfer in only one direction.Duplex: Between two communication devices, bidirectional data transfer is allowed. Typically, there are two duplex modes: half-duplex and full-duplex.Full-Duplex A full-duplex system permits simultaneous bidirectional data transmission between two devices. Common telephones and mobile phones are examples of full-duple
