Secure Passive Optical Networks (PON, GPON, EPON)
SecurLAN® is a technology invented by Fiber SenSys, Inc. (FSI) in 1996. It is a versatile physical network sensor that is enabled using several deployment options.
SecurLAN for PON technology involves dark (unused) fibers, in optical cables, that are used as distributed sensors in order to determine if an intruder is trying to cut into the cable and tap the fiber-optic network. It can also be used to ensure network uptime and detect either intentional or accidental physical network intrusions. SecurLAN is designed to detect small amounts of strain that are transferred to the sensing fiber when the cable is accessed. When the electro-optical alarm processing unit (APU) senses an intrusion, it signals an alarm, allowing the investigation of the intrusion. The system also enables the shut-down or re-routing of secure data.
Since SecurLAN uses dark fiber (where no data is transmitting through the spare fiber), it is unaffected by data protocols or bandwidth in the PON. The only distinguishing feature of the PON (that is of importance to SecurLAN) is the type of sensing fiber (SM or MM) in the cable that houses the PON transmission fibers.
With the FSI PON solution, detection zones are identified to a specific optical network unit (ONU) or a group of ONU's, allowing for maximum design flexibility. It has also been demonstrated that the FSI Secure PON solution offers the lowest cost per zone in this emerging marketplace. This capability also significantly reduces the cost of physically securing the PON, GPON or EPON architecture. A point-to-multipoint monitoring configuration allows multiple offices or workstations to be protected by a single alarm system port rather than each requiring its own port. It is technically possible to protect several hundred end-user drops with the FSI 8-zone alarm processor unit (APU), resulting in an efficient security systems design.
