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.
Features
- Four completely independent and isolated Ethernet streams
- Low latency
- Auto negotiation for 10/100/1000 speeds on all ports
- Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK®
- VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
- Optical output wavelengths at 1310nm, 1550nm and up to sixteen CWDM wavelengths (ITU-T G.694.2 compliant)
- DWDM wavelengths (ITU-T G.694.1 compliant) also available
- Fully hot-swappable from front of frame
- Optical SFP supportable from the rear
Status Indication
