Ethernet Fiber Transceiver

Interact with this product in a Layout Tool:

The 7707ET is a VistaLINK® capable Ethernet Fiber Transceiver that provides an economical method of transmitting two 10BaseT Ethernet channels or one 100Base-TX Ethernet channel over optical fiber. The transceiver is IEEE 802.3 10BASE-T and IEEE 802.3u 100BASE-TX compliant. It mediates between a 10/100BASE-TX segment and supports both full duplex and half-duplex operation. Monitoring of card status and parameters is provided locally at the card edge and remotely via VistaLINK®. A pair of 7707ET transceivers permits full duplex communication over single or dual optical fibers. Diagnostic LEDs provide indication of power, link status and data reception.

Multiple versions of the 7707ET are available to address single-mode/multi-mode fiber, single/dual fiber and CWDM/DWDM applications (see Applications Configuration chart)

The 7707ET 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.
