Quad Ethernet Fiber Transceiver

Interact with this product in a Layout Tool:

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.


  • Four completely independent and isolated Ethernet streams
  • Auto negotiation for 10/100 speeds on all ports
  • Built-in Ethernet switches for isolation of each transmission end
  • Comprehensive signal and card status monitoring via four digit card-edge display or remotely through SNMP and VistaLINK® capability
  • 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
  • SC/PC, FC/PC Connector options
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • Status Indication

  • Frame Status
  • 10/100 speed indication for all copper ports
  • Full duplex/Collision Indication for all copper ports
  • Link activity for copper port
  • Received optical power level
