A
fiber splitter is
a device intended to split an input optical signal into two or more output
signals. They are sometimes referred to as optical splitters or beam splitters.
Utilizing technologies such as planar lightwave circuit (PLC) technology and
fused biconical tapering, this division is completed. The numbers 1x2, 1x4,
1x8, and 1x16, which indicate the number of input ports and the number of
output ports, respectively, are the most popular varieties of fiber splitters.
Fiber splitters' uses include:
PONs or passive optical networks:
In PON topologies, where a single optical fiber is split to serve numerous
end-users, such as residences or companies, fiber splitters are commonly
employed.
Fiber to the Home (FTTH): Fiber splitters are essential
components in FTTH installations because they distribute optical signals to
individual customers, allowing for high-speed internet access.
Sensor Networks: To divide and distribute
signals from several sensors and enable effective data gathering, fiber
splitters are employed in optical sensor networks.
Comprehending Fiber Couplers: In contrast, fiber couplers are
apparatuses intended to merge several optical signals into a solitary output
signal. Based on how they work, couplers may be divided into several
categories, including polarization-maintaining, wavelength-selective, and fused
couplers.
Utilizing Fiber Couplers:
Fiber coupler is widely used in wavelength division
multiplexing (WDM) systems, which combine numerous signals at various
wavelengths onto a single fiber for transmission.
Fiber Optic Sensors: In a variety of fiber optic
sensor applications, couplers are used to integrate signals from many sensors
for centralized processing.
Optical Amplifier Systems: Before amplification, signals
from several input fibers are combined in optical amplifier systems using
couplers.
The distinctions between couplers
and fiber splitters
Usability: Their usefulness is the main
point of differentiation. Couplers combine numerous signals, whereas splitters
separate an optical signal.
Number of Ports: Couplers are frequently
identified by their split ratio, such as 50/50 or 90/10, which indicates the
allocation of power across the output ports. Splitters are generally stated as
1xN (one input, many outputs).
Applications: Fiber splitter is frequently utilized in situations like FTTH and PONs where signal dispersion is necessary. Conversely, couplers are used in applications like WDM systems where signal merging is required.
