What are the SFP and QSFP Ports of Switches?
The SFP port of a Gigabit switch is an important concept when it comes to computer networking and data transfer speeds. The SFP (Small Form-Factor Pluggable) port, is also known as the mini GBIC (Gigabit Interface Converter). The SFP module was first introduced in 2001 and has caused a major change in networking. The introduction …
The Latest Progress of 400G and 800G Coherent Optical Transmission Standards
The rapid development of data center networks has led to a soaring demand for optical network bandwidth, which grows at an annual rate of over 20%, driving the optical transmission network towards higher-speed and higher-capacity solutions. At present, single-wavelength 100G/200G WDM systems have been commercially deployed on a large scale in operators’ backbone networks, and …
