Plastic Plastic Fiber Couplers (Splitters)
Description
Fiber couplers, or splitters, are special fiber optic devices with one or more input
fibers for distributing optical signals into two or more output fibers. The optical
light is passively split into multiple output signals (fibers), each containing light
with properties identical to the original except for reduced amplitude. Because
the splitter is a passive device it is immune to EMI, consumes no electrical
power and does not add noise to system design. The splitter’s passive design is
bi-directional and operationally independent of wavelength, constrained only by
the physical properties of the PMMA fiber core.
Fiber couplers have input and output configurations defined as M×N. M is the
number of input ports and is one or greater. N is the number of output ports and
is always equal to or greater than M. When there are multiple inputs, output
signals are always a combination of the input signals – a coupler can also be
considered a combiner.
Fiber optic couplers or splitters are available in a wide range of styles and sizes
to split or combine light with minimal loss. All couplers are manufactured using
a very simple proprietary process that produces reliable, low-cost devices. They
are physically rugged and insensitive to operating temperatures. Couplers can be
fabricated in custom fiber lengths and/or with terminations of any type.
