Passive Optical Bypass Module PRODUCT NUMBER: POBM-C1CX4-P0A Specification Passive Optical Bypass Module P O B M C 1 C X 4 P 0 A Page 1 Formerica OptoElectronics Inc. MAR-18-2019 Rev.6.3 Passive Optical Bypass Module PRODUCT NUMBER: POBM-C1CX4-P0A Features Reliable Passive Fiber Bypass(Non-latching) Low Bypass Loss and Return Loss Available in 50/125m Multimode Fiber PCB Mountable Type Compliant with IEEE 802.3z Controlled by NICs CPLD to Perform Programmable Normal and Bypass Modes at Powerless, System Hangs, and Software Request Four Dual LC OM3 Adapter Compact Format and ROHS Compliant Product Overview FormericaOEsHigh Density Passive Optical Bypass Module is a compact box that contains 1 optical bypass switchwhich can becontrolled by the controller of In-Line equipment to perform the Fail-to-Wire optical bypass function. The FormericaOEsPassive Optical Bypass Module (POBM) is targeted to In-Line network system (e.g. IPS: Intrusion Prevention System, IES: Industrial Ethernet Switching, WAN Optimization System, and Application Switch, etc.) with high availabilityin maintaining network connectivity when power failure or system failure. This POBM supports Normal and Bypass modes.In Normal mode, each port is an independent interface directly linked to optical transceiver on In-Line equipment by optical patch cord. In Bypass mode, all packets received from one port are transmitted to the adjacent portin POBM. Thus, This POBM can bypass its Ethernet ports when thereis host-system failure, power off, or upon software request. This POBM can also be mounted and integrated with any kind of NIC by a simple signal connector. FormericaOEsPassive Optical Bypass Module is suitable for connecting with In-Line equipment inmeeting the requirement of Fail-Over systems. When the In-Line unit is not on or is in Bypass Mode, the relays within the Passive Optical 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 is operating normally, it supplies power to the switch through a connector PIN. This compact module provides network users excellent and cost effective protection for your network. Page 2 Formerica OptoElectronics Inc. MAR-18-2019 Rev.6.3
