  • What is the difference between QSFP28 and QSFP28 DD?

    The key difference between QSFP28 (Quad Small Form-Factor Pluggable 28) and QSFP28 DD (Quad Small Form-Factor Pluggable 28 Double Density) lies in the number of electrical lanes and the potential data rates they can support. Both are form factors used for high-speed data transmission, but QSFP28 DD is designed to provide double the electrical lanes, allowing for higher data rates.QSFP28 (Quad Smal

  • What is the difference between 10G and 10ge?

    The terms "10G" and "10GE" are related to network speeds, specifically referring to 10 Gigabit Ethernet, but they may be used in different contexts. Let's break down their meanings:10G:Meaning: "10G" simply stands for 10 Gigabits, and it is often used as an abbreviation for 10 Gigabit per second (Gbps).Usage: It is a general term used to describe network speeds, i

  • What type of cable is QSFP-40G-SR-BD?

    The QSFP-40G-SR-BD transceiver is designed for use with a specific type of multimode fiber optic cable known as "BiDi" or "Bidirectional" fiber. The "BD" in the transceiver's name stands for Bidirectional.Here are some key characteristics of QSFP-40G-SR-BD:Data Rate: QSFP-40G-SR-BD supports a data rate of 40 gigabits per second (Gbps).Wavelengths: Bidirectional (B

  • What is the difference between Class B and Class C SFP?

    Class B and Class C SFP (Small Form-Factor Pluggable) refer to different types of transceiver modules used in networking equipment. The main differences between the two are as follows:1. Transmission Distance: Class B SFP modules typically support shorter transmission distances, usually up to 10 kilometers, while Class C SFP modules support longer transmission distances, up to 100 kilometers.2. Po

  • How many lanes are in QSFP28?

    A QSFP28 (Quad Small Form-Factor Pluggable 28) transceiver supports a total of four electrical lanes. Each lane can carry data at a rate of up to 25 gigabits per second (Gbps). The aggregate data rate of a QSFP28 module is thus 100 Gbps, combining the four lanes.The design of QSFP28 allows it to support high-speed data transmission, making it a common choice for applications such as 100 Gigabit Et
