The 7707ET-4 is a VistaLINK capable quad Ethernet fiber transceiver that transmits up to four separate 10/100BaseT Ethernet channels over optical fiber. Monitoring and control of card status and parameters is provided locally at the card edge and remotely via VistaLINK. A pair of 7707ET-4 transceivers permits full duplex communication of all four channels over a single or dual optical fiber(s). The 7707ET-4 provides four RJ-45 input connectors and either one or two fiber optic output connectors. Multiple versions of the 7707ET-4 are available to address single-mode/multi-mode fiber, single/dual fiber and CWDM/DWDM applications.
