Fiber Sensys, Inc
Fiber Defender FD208N Alarm Processor
Fiber Optic Fiber Instrusion System

The Fiber Defender series Model FD-208 Alarm
Processing Unit (APU) is an ideal alarm processor for
use in applications that require the intrusion detection
control electronics to be placed in a remote location.
The FD-208 requires insensitive leads to connect to a
deployed sensor cable, leaving only the fiber optic
sensor cable in the detection zone. This allows the
FD-208 system to be deployed successfully in the
presence of EMI/RFI, in corrosive or flammable
environments, and in extreme temperatures where
other sensor systems fail. Airports, oil pipelines, highend
estates, power plants, petro-chemical
facilities, military compounds, and electrical
substations are a few examples of deployment
applications where the FD-208 is ideal.

4G LTE router LR77 v2 provides wireless connection of various equipment and devices via Ethernet interface 10/100 or serial interfaces to the Internet or intranet. 4G router LR77 v2 is an ideal wireless data transfer device for applications transferring large data loads because of ultimately fast data transfer speed in LTE network reaching up to 100 Mbit/s (download) and up to 50 Mbit/s for upload.
