  • SFP vs SFP+ vs QSFP: What's the difference?

    Walsun is a technology solutions provider that offers a variety of networking and communication products. In the context of SFP (Small Form-Factor Pluggable), SFP+ (enhanced Small Form-Factor Pluggable), and QSFP (Quad Small Form-Factor Pluggable), here are the general differences:SFP (Small Form-Factor Pluggable):Data Rate: SFP modules support data rates of up to 1 Gbps (Gigabit per second).Appli

  • What speed is QSFP DD supported?

    QSFP-DD (Quad Small Form-Factor Pluggable Double Density) is a high-speed transceiver module that provides double the density of ports compared to traditional QSFP modules. QSFP-DD is designed to support various data rates depending on the specific variant. 200 Gigabit Ethernet (200GbE): QSFP-DD modules can support a data rate of 200 Gbps, allowing for high-speed network connections.400 Gigabit Et

  • What is the difference between AOC and DAC?

    AOC (Active Optical Cable) and DAC (Direct Attach Cable) are both types of cables used in data center and high-performance computing environments to connect networking equipment. While both serve similar purposes, there are key differences between the two: AOC (Active Optical Cable):Technology: AOCs use optical fibers to transmit data. They contain optical transceivers on each end of the cabl

  • What is the difference between CWDM4 and FR1?

    CWDM4 (Coarse Wavelength Division Multiplexing 4) and FR1 (Frequency Range 1) are terms used in the context of optical communication, specifically in the development of 5G networks. They refer to different aspects of the communication infrastructure. CWDM4 (Coarse Wavelength Division Multiplexing 4):Wavelength Division Multiplexing (WDM): CWDM is a technology that allows multiple data streams

  • What is the difference between GPON and BiDi?

    GPON (Gigabit Passive Optical Network) and BiDi (Bidirectional) refer to different technologies used in the field of fiber-optic communication, particularly in the context of passive optical networks. Here are the key differences between GPON and BiDi: GPON (Gigabit Passive Optical Network):Architecture: GPON is a point-to-multipoint optical access technology that uses a passive optical split
