FR4 and MCPCB (Metal Core Printed Circuit Board) are different types of printed circuit boards, and their main differences lie in their construction and materials.FR4:Material: FR4 is a type of electrical-grade laminate made from woven fiberglass cloth impregnated with epoxy resin. The name "FR4" stands for Flame Retardant 4, indicating its fire-resistant properties.Construction: FR4 boa

The speed of a 1000BASE SFP (Small Form-factor Pluggable) module is 1 gigabit per second (Gbps). The "1000BASE" designation indicates that the module operates at a data rate of 1000 megabits per second, which is equivalent to 1 gigabit per second. These modules are commonly used for Gigabit Ethernet connections and are widely employed in networking equipment such as switches, routers, an

SFP-DD (Small Form-factor Pluggable Double Density) is a next-generation optical transceiver form factor that supports higher data rates compared to traditional SFP (Small Form-factor Pluggable) modules. SFP-DD modules are designed to double the data rate density while retaining backward compatibility with existing SFP ports. The data rates supported by SFP-DD modules include:SFP-DD (Single Channe

The bandwidth of QSFP (Quad Small Form-factor Pluggable) modules can vary depending on the specific type and version. QSFP modules are commonly used in high-speed data communication applications, including Ethernet, InfiniBand, and Fibre Channel. The most common types include QSFP28 (100 Gbps) and QSFP-DD (Double Density) which can support higher data rates such as 200 Gbps or 400 Gbps.For example

QSFP-DD (Quad Small Form-factor Pluggable Double Density) modules use a different connector than traditional QSFP modules. The QSFP-DD connector is designed to accommodate the increased number of electrical lanes and support higher data rates. It has a double-density design, allowing for more contact pins.The QSFP-DD connector has a total of 8 electrical lanes, compared to the 4 lanes in a standar
