268 x 44 x 128 mm (W x H x D)
8FE + 1 fixed 1000Base-X 1.25G EPON Port
Managed Carrier-Class L2 Ethernet Switch


  • 268 x 44 x 128 mm (W x H x D)
  • 8FE + 1 fixed 1000Base-X 1.25G EPON Port
  • Managed Carrier-Class L2 Ethernet Switch

E3208E is a Fast Ethernet L2 switch used in access network segments to provide broadband multimedia service. It can provide high performance switching service to subscribers. It can be also deployed economically because it is based on 100Mbps downlink speed as FE and an uplink port as GE-PON.

E3208E is the best solution for medium size networks with high traffic volumes. E3208E also provides advanced network management and switching functions that follow the world standard. E3208E consists of eight FE ports and one Uplink module as GE-PON port.
