Monitoring of fiber optic signals is a standard capability. The Fidra displays the level of three
receivers on the front panel.Alarming for a drop in signal level, receive fail, transmitter failure, power
supply failure, and test mode function are all included.
The enclosure is a 19-inch rack-mount, by 1 Unit high chassis by 11 inches deep. The front panel
contains the 2x20 Liquid Crystal Display (LCD), and LEDs to indicate status. The rear panel contains
3 SFP cages and terminal block connections for the alarm relay, cutout switch, and power supply
connections.
FEATURES
DESIGN: Fidra has been designed for ease of setup, use and field modification. Each Fidra chassis
can accomodate up to 2 Fidra modules. Each module can control up to 3 SFP modules. The unit’s
design allows for quick system monitoring and diagnosis. The use of SFP’s allows for easy change or
replacementoffiberheads. TheremovableterminalblockallowsforFidramodulereplacementwithout
the need to rewire.
PROGRAMMABILITY: Programming is performed using the embedded web server and any internet
browser. Signal routing and alarm setup are programmed using the web server and test modes are
controlled by the front panel switches. The transmitter cutout is controlled by an auxiliary switch wired
to the terminal block.
COMMUNICATIONS: Up to 3 SFP modules can be mounted in the SFP cages in the rear of the unit.
Fidra converts any optical signal to an electrical signal and back to an optical signal. Channel delay is
measured in microseconds. Matching protocols is not required as Fidra passes through any data
received to the transmit port programmed in the logic. Converting from singlemode to multimode and
from frequency fiber (i.e. 850 nm) to another (i.e. 1310nm) is done automatically as long as the data
rates are the same.
POWER SUPPLIES: The power supply supports DC Input power from 24VDC to 125VDC. 250VDC
input power supplies are available.
SUBSTATION HARDENED: The Fidra meets all requirements of IEEE Standard 1613, class 2.
Environment temperatures can range from –20 degrees C to +65 degrees C.
DIAGNOSTICS: Five front panel LEDs monitor the receive levels, including drop and loss, transmitter
failure,whethertheunitisincutoutortestmode,andpowercondition. Thefrontpaneldisplayindicates
the unit’s IP address, receive level, whether an individual receiver is a drop or loss state, indicates
cutout or test mode, transmitter status, and indicates which receiver is assigned to each transmitter.
ROUTING: Fidra allows any fiber receiver to be assigned to any fiber transmitter. There are three sets
of programs: Normal, Test Mode 1, and Test Mode 2. These modes are programmed by the user and
controlled by the toggle switches on the front panel. Local and remote loopbacks as well as bypassing
an IED are performed using this method.
CUTOUT: A cutout of all communications is available by energizing an input on the terminal block.
Activating the cutout disables all transmitters. A panel switch or remote relay can be used for this
safety feature.
