RAD’s SFP (small form-factor pluggable) transceivers are hot-swappable, input/output transceiver units converting optical and electrical media. Providing a wide range of detachable interfaces to multimode/single-mode optic fibers and UTP/coaxial electrical cables, they also allow the transport of Fast Ethernet and Gigabit Ethernet LAN packets over TDM-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks. In addition to facilitating efficient design of host devices and flexible network planning, RAD’s miniature transceiver units enable significant savings in system maintenance and upgrade costs.
