4X4(FOBM-Dual Port) Optical Bypass Module (Latching Type)
Description
LLI’s Dual Port Gigabit Ethernet Fiber Bypass Module is a compact module that contains two Gigabit Ethernet ports and can integrated with LAN ports controllers to be a Network Interface Card (NIC). The LLI’s Dual Port SX Fiber Bypass Module is targeted to in-line network system that maintains network connectivity when power failure or system fails. LLI’s Dual Port SX Fiber Bypass Module supports Normal and Bypass modes. LLI’s Dual Port SX Fiber Bypass Module can Bypass or Block its Ethernet ports on a host system failure, power off, or upon software request.
Key Features
  • Compact Format
  • Low Return-Loss
  • Multi Mode Available
  • PCB Mountable
  • RoHS Compliance

Applications
  • Network interface card or external bypass unit
  • Industrial Ethernet ring switch under power failure or system hang
  • Node Bypass Protection
