1.3.2 Terminology
The following is a brief description of the terms
specific to the Fiber Optic Prism Switch.
Bandwidth The range of operating
wavelengths over which
performance parameters are
specified.
Calls attention to a procedure,
practice, or condition which, if
not correctly adhered to, could
result in damage to the product
(e.g., refer to accompanying
documents).
Section 1 - Introduction 1- 3
Directivity The ratio of the power returned
to any other input port to the
launched power, expressed in
dB.
Excess Loss The ratio of the total power at
all output ports to the launched
power, expressed in dB.
Isolation The ratio of the power at an
output port in the transmitted
wavelength band to that in the
extinguished wavelength band.
Non-Latching These style of switches require
no power to maintain one
position and a constant +5 VDC
drive current to maintain the
other position.
Polarization-Dependent
Loss (PDL) The maximum (peak to peak)
variation in insertion loss as the
input polarization varies,
expressed in dB.
Port Configuration Number of input ports x number
of output ports (e.g., 2x2).
Return Loss The ratio of the power returned
to the input port to the launched
power expressed in dB.
Uniformity The difference between
maximum and minimum
insertion losses.
1- 4 Section 1 - Introduction
1.4 Product Overview
Newport's 1x2 and 2x2 Prism Switch provides channel
selection from one or two input fibers to two output
fibers, using a moving prism between fixed
collimators.
Newport's 1x2 and 2x2 switches are actuated
electrically and require +5 VDC to switch position.
The switches are housed in a compact,
environmentally stable package designed for mounting
on printed circuit boards or within a module.
Key Features:
•Single and multimode fiber optic switch design
•1x2 and 2x2 configurations are available
•Low insertion loss and low back reflection
•High durability – greater than 10 million cycles.
