    ▶Different Transmission Distances: Optical ports with optical modules can transmit data over distances exceeding 100KM, while Ethernet ports connected with cables typically have a maximum transmission distance of around 100 meters. In reality, SFP transmission distance is defined by optical design—not data rate. Recent techniques related to the optical switching, and main challenges limiting the practical deployments of optical switches in data. An SFP port on a Gigabit switch is a modular interface that accepts Small Form-Factor Pluggable (SFP) transceiver modules. In a number of applications such as campus and inter-datacenter connectivity support for distances in excess of 400.
