  • How to use optical port and optical module

    How to use optical port and optical module

    Install an optical module on a port before connecting optical fibers to the transceiver module. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. The method used to install a copper transceiver module is the same, except that the copper transceiver module connects to a network cable instead of optical fibers. Whether you're upgrading bandwidth, replacing a faulty unit, or reconfiguring your topology, knowing. SFP and other optical modules are key components of any fibre optic network. It's essential to understand how to properly install and configure an SFP.
