the required network speed and\r\n            transmission frequency. The RJ45 interface may physically fit both\r\n            cable systems while the internal circuit still limits the completed\r\n            channel.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Does an RJ45 surge protector reduce network speed?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            A correctly selected and installed SPD should preserve its declared\r\n            transmission performance. A mismatched product can cause a link to\r\n            negotiate from 1Gbps down to 100Mbps, increase packet errors or\r\n            create intermittent disconnections.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Can a 100Mbps RJ45 SPD be used on a Gigabit network?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            No. A product with a documented maximum rate of 100Mbps should not\r\n            be specified for 1000BASE-T. Gigabit Ethernet requires all four\r\n            twisted pairs and suitable high-frequency transmission performance.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Can a non-PoE RJ45 surge protector be installed on a PoE cable?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            Not unless the manufacturer explicitly confirms the PoE voltage,\r\n            load current and powered-pair configuration. A non-PoE data-line\r\n            protector may not safely carry continuous PoE power.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Does shielded Ethernet cable remove the need for grounding?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            No. The cable shield helps manage electromagnetic interference, but\r\n            it does not automatically replace the SPD\u2019s short connection to the\r\n            local PE or equipotential bonding system.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>Should an Ethernet surge protector be installed at both ends?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            Protection at both ends is commonly appropriate for outdoor,\r\n            rooftop or inter-building copper Ethernet links. Each SPD should be\r\n            installed at the local protection boundary and bonded to the local\r\n            equipotential system.\r\n          <\/p>\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>What matters more: insertion loss or surge-current rating?<\/summary>\r\n        <div class=\"ly-rj45-faq-answer\">\r\n          <p>\r\n            Both matter. Transmission parameters determine whether the network\r\n            remains stable, while surge parameters determine the protection\r\n            capability.
