Relationship Between The Coupler And Splitter
Relationship between the coupler and splitter:
In fact, splitter is named for the function of the device, coupler named for
its working principle, splitter may be based coupler, and may be based on the
waveguide or the separating element, coupler can be done either the splitter,
but also can be done WDM, attenuator.
Couplers:
Fiber optic couplers either split optical
signals into multiple paths or combine multiple signals on one path. Optical
signals are more complex than electrical signals, making optical couplers
trickier to design than their electrical counterparts. Like electrical
currents, a flow of signal carriers, in this case photons, comprise the optical
signal. However, an optical signal does not flow through the receiver to the
ground. Rather, at the receiver, a detector absorbs the signal flow. Multiple
receivers, connected in a series, would receive no signal past the first
receiver which would absorb the entire signal. Thus, multiple parallel optical
output ports must divide the signal between the ports, reducing its magnitude.
The number of input and output ports, expressed as an N x M configuration,
characterizes a coupler. The letter N represents the number of input fibers,
and M represents the number of output fibers. Fused couplers can be made in any
configuration, but they commonly use multiples of two (2 x 2, 4 x 4, 8 x 8,
etc.).
Splitter:
Fiber
optic splitter is a device that split the fiber
optic light into several parts by a certain ratio. The simplest couplers are
fiber optic splitters. These devices possess at least three ports but may have
more than 32 for more complex devices. Fiber optic splitters are important
passive components used in FTTX networks. But two kinds of fiber splitters are
popular used, one is the traditional fused type fiber optic splitter (FBT
splitter), which features competitive prices; the other is PLC fiber optic
splitter, which is compact size and suit for density applications. Both of them
have its advantages to suit for different requirement.
include input and output part cable length, splitting ratio, working wavelength
and with what kind of fiber optic connectors. Just like fiber patch cable,
fiber splitters are usually with 0.9mm, 2mm or 3mm cables. 0.9mm outer diameter
cable is mostly used in stainless steel tube package fiber optic splitters,
while 2mm and 3mm cables are mostly used in box type package fiber splitters.
Based on working wavelength difference there are single window and dual window
fiber optic splitters. And there are single mode fiber splitter and multimode
fiber splitter. Typical connectors installed on the fiber optic splitters are
FC or SC type.
Fiber optic couplers or splitters are
available in a selection of styles and sizes to separate or combine light with
minimal loss. All couplers are produced employing a proprietary procedure that
produces reliable, low-cost devices. They’re rugged and impervious to common
high operating temperatures. Couplers can be fabricated with custom fiber
lengths or with terminations of any type. For more information about Coupler or
