  • Are Cisco SFP modules hot-swappable?

    Yes, Cisco SFP (Small Form-factor Pluggable) modules are designed to be hot-swappable. Hot-swapping refers to the ability to insert or remove a module from a networking device without powering down the device. This feature allows for easier maintenance, upgrades, and replacements without interrupting the operation of the overall network.When hot-swapping a Cisco SFP module, it's important to f

  • What is the difference between SFP port and SFP module?

    The terms "SFP port" and "SFP module" refer to different components in a network system, and understanding their distinctions is essential for networking professionals. Here's a breakdown of the differences:SFP Port:Definition: An SFP port (Small Form-factor Pluggable port) is a physical interface or receptacle on a networking device, such as a switch, router, or network in

  • What is the power level range of SFP?

    The power level range of SFP (Small Form-factor Pluggable) modules can vary depending on factors such as the specific type of SFP module, the data rate it supports, and whether it is an optical or electrical module. Generally, the power levels are specified in terms of transmit (TX) power and receive (RX) power. Here are some general guidelines:TX Power (Transmit Power): This refers to the optical

  • What is the difference between SFP 10G ER and SFP 10G ZR?

    SFP 10G ER (Extended Range) and SFP 10G ZR (Zero Dispersion Shifted Reach) are both types of 10 Gigabit Ethernet (10GbE) transceiver modules designed for extended-range optical connectivity. While they share similarities, there are differences in their intended use cases, reach, and specifications:Reach:SFP 10G ER (Extended Range): Typically designed for extended-range connections and can support

  • Is OM1 obsolete?

    OM1 (Optical Multimode 1) fiber optic cabling is considered an older and less capable multimode fiber type compared to more recent generations. While it may not be entirely obsolete, its use is limited, especially in comparison to newer multimode fiber types such as OM3 and OM4. OM1 has several characteristics that make it less suitable for modern high-speed networking applications:Lower Bandwidth
