FR1 and FR4 refer to different types of substrate materials used in printed circuit boards (PCBs). Here are the key differences between FR1 and FR4 PCBs:Composition:FR1 (Flame Retardant 1): FR1 is typically composed of paper reinforced with phenolic resin. The paper provides the substrate, and phenolic resin acts as a binding material. It is a relatively inexpensive material.FR4 (Flame Retardant 4

QSFP28 (Quad Small Form-Factor Pluggable 28) transceivers are widely used in data center and high-performance computing environments for high-speed data transmission. These transceivers support data rates of 100 gigabits per second (Gb/s) and are designed for various applications. Here are some common types of QSFP28 transceivers:100G QSFP28QSFP28 SR4 (Short-Range 4):Designed for short-distance tr

40G SR4 QSFP + Optical Module is an ideal solution for short distance interconnection of 40G networks with many advantages, but 40G QSFP + AOC also has similar functions of Optical Module and is no worse than 40G SR4 QSFP + Optical Module, and it can even be used to transmit signals instead of it. Since both can interconnect over short distances at 40G, what is the difference between them? Why are

QSFP, which stands for Quad Small Form-Factor Pluggable, is a compact and high-density optical transceiver module used in data communication and networking applications. The primary purpose of QSFP is to facilitate high-speed data transmission over optical fiber or copper cables. QSFP modules support various data rates and are commonly used in data centers, telecommunications networks, and high-pe

The capacity of QSFP (Quad Small Form-Factor Pluggable) modules varies based on the specific variant. QSFP modules come in different types, each supporting different data rates and capacities. As of my last knowledge update in January 2022, here are common QSFP types and their respective capacities: QSFP:Capacity: QSFP modules typically support data rates of up to 40 gigabits per second (Gbps
