Or if you don’t need the distance of fiber, you can consider converting SFP to RJ45, which will depend on the switch to determine what copper speeds (10/100/1000) are supported on a copper SFP. Especially in some case, Copper SFP will make sense if the switch on one side does not have copper ports but SFP slots and the switch on the other side only has copper and can’t be fitted with fiber ports. And SFP ports are primarily for allowing fiber connections over longer distances. Copper SFP is popular to be used for short range uplinks, as it’s easier and cheaper to use 1G copper SFPs and patch cables. For short-distance links on a Gigabit switch, it makes no difference if you use SFP ports or RJ45 ports to interconnect switches. GLC-T is a typical Cisco 1000BASE-T SFP copper RJ-45 transceiver. The Gigabit RJ45 copper SFP transceiver supports 1000Mbps over Cat5 cables with RJ45 connector interface, which operates on standard Cat5 unshielded twisted-pair copper cabling of link lengths up to 100 m (328 ft). This article will explore their respective strengths and weaknesses and reveal insights into how IT experts are to proceed.Ĭopper SFP vs Optical SFP: Copper SFP Is a Balanced Choice in Environment Restrictions This battle is also being waged in SFP transceivers, there is a measurable difference in the copper SFP vs optical SFP. But many end-user organizations still face tough decision about which type is the best overall value for their current and future projected needs. In some ways, the copper matters most to IT experts and data center decision makers. The speed difference between the two media is considerably smaller. However, with recent advances in copper technology, the copper presents the same step-ladder upgrade path. Fiber seems to operate as a rival to copper rather than a replacement until now, it has already established a niche in the industry. The war of copper vs fiber has raged for years.
