Explanation Of SFP Optical Module Plugging And Unplugging Unlocking Method

Time: 2023-06-25
1. Optical Module Interface Structure Standard
        The optical module structure and the corresponding host optical port comply with MSA standards. Unified standards are defined for housing dimensions and unlocking mechanisms, allowing smooth insertion, locking, unlocking, and removal of optical modules from the host port. SFP and QSFP are the most common optical port types in current mainstream equipment.
2. SFP Optical Module Installation and Unlocking Methods
        The SFP interface is one of the highest-density packaging interfaces for host equipment on the market.
        To use an SFP optical module, first confirm that the host port is SFP-type. Align the SFP module with the optical port and insert it horizontally, pressing firmly until the bottom of the module engages with the locking spring of the optical interface.

        After installing the optical module, insert the corresponding fiber jumper horizontally into the module (multimode fiber for multimode modules, single-mode fiber for single-mode modules). A slight "click" or tactile snap indicates the fiber is fully seated.
        Once inserted, gently pull the module outward to verify it is locked in place. If it cannot be pulled out easily, installation is complete.

        To remove the optical module, first unplug the fiber jumper, then flip open the pull-tab on the module and pull it out horizontally.
        Do not force the module out without opening the pull-tab first. Doing so may damage the module or deform the host’s internal locking spring, affecting future module insertion and unlocking.
        After removal, place a dust cap on unused modules to prevent contamination of the internal optical path.
