Kingfisher KI5000 Series User Manual

Description

The KI5000 series Optical Power Leveler (OPL) is a device to stabilise the receive power level in a single mode fiber
optic transmission system with LC-PC connectors, operating at 1270~1330 nm or 1490~1610 nm depending on
model.
The OPL controls the output power level in one fiber with either single direction or bidirectional transmission, in
which case attenuation is approximately identical in both directions.
Optical output power is kept at a stable level by use of an attenuator coupled with an internal power detector and
control circuit.

Device Setup and Operation

The OPL clips onto on a 35 mm DIN rail. Pull latch to mount/unmount device onto/from rail.
Nominal input voltage range is 12 - 48 VDC, power consumption < 0.1 W.
The DC power can be connected (to connectors labelled "DC input") in either polarity. Use a pointy tool to
depress white latches beside each connector to connect/disconnect wires.
OPL optical interface is a duplex single mode LC/PC optical connector.
Connect optical port labelled "IN" to the external line
Connect port labelled "OUT" to local transceiver.
The device output power has been factory set to the -10 dBm mid-point of the transceiver operating range.
Typically, no further user action is required after installation of power and optical fiber.
Two LED status indicators show green when the system is in stable operation.
