Product ManualManual

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. (See Application Configurations chart below)

The 7707ET-4 occupies one or two card slots and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
