Product 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 inline 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, and can be controlled to perform the Block mode. In Normal mode, the ports are independent interfaces. In Bypass mode, all packets received from one port are transmitted to the adjacent port. In Block mode, the module blocks the route. 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. LLI's Dual Port SX Fiber Bypass Module can be integrated with Intel 82571, 82575, or 82576 Controllers. The Fiber Bypass Module utilizes fiber-to-fiber technology over an angled surface to achieve ultra low losses and crosstalk. It is suitable for connecting with in-line equipments for power failure or system maintenance. When the In-Line unit is not on or is in bypass mode, the relays within the Fiber Bypass Module are set to bridge the optical signals directly through the
switch, completely bypassing the In-Line equipment. If the In-Line equipment is on and operating normally, then it supplies power to the
switch through a high speed connector PIN. Compact and competitive cost, this module provides excellent performance on your network. Lightwave Link 4x4 optical bypass box fully complies with RoHS Directive 2002/95/EC (2008/385/EC).
