Product Manual
The 7708GT-4 is a VistaLINK®-capable Quad Gigabit Ethernet Fiber Transceiver for up to four independent 10/100/1000BaseT Ethernet channels over optical fiber. Monitoring of card status and parameters are provided locally at the card edge and remotely via VistaLINK®. A pair of 7708GT-4 transceivers permit full duplex communication of all four channels up to 1GB/s each over a pair of optical fibers.
The 7708GT-4 occupies one card slot 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.
