FAQs about Upstream equipment suppliers for optical modules

Does stacking require optical modules

Stack setup just requires ordinary service cables instead of dedicated stack cables. Electrical ports can be connected using Category 6A or Category 7 cables. Since DAC, AOC, and optical modules can all realize the stacking of switches, do you know when to use DAC or AOC? When to use optical module + optical fiber jumper? Firstly, let's talk about DAC, which is a cable assembly with fixed length and fixed modules at both ends. When setting up a stack, ensure that optical. To enhance network scalability, reliability, and ease of management, these switches support stacking technology. Stack master is the core switch to manage other stack members and it stores the running configuration files for the whole switch stacking. Switch stacking is to combine multiple switch devices that support stacking features, and then use dedicated cables and modules to plug in ports with stacking functions, connect these switches together, and combine them logically into a switching device.
