Fiber Optic PLC Splitter

What are the Advantages of Optical Cable Splitter
In general, an optical splitter has many input and output terminals to attain the branch of the light
beams and maximize the functionality of optical network circuits. The passive optical splitter can split, or
separate, an incident light beam into several light beams at a certain ratio. A fiber optic splitter, better
known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power
distribution device. It is similar to a coaxial cable transmission system. The optical network system
makes use of an optical signal coupled to the branch distribution. The fiber optic splitter is one of the
most significant passive devices in the optical fiber link. It is an optical fiber tandem device with a lot of
input and output terminals, especially applicable to a passive optical network to connect the MDF and
the terminal equipment and to branch the optical signal.
There are different types of optical cable splitter which can be divided into Fused Biconical Taper (FBT)
splitter and Planar Light wave Circuit (PLC) splitters. The FBT splitter is one of the popular ones as FBT
splitters are widely accepted and used in passive networks, especially for instances where the split
configuration is smaller. The FBT splitter uses two (or more) fibers. The fibers' coating layer is removed.
Both fibers, at the same time, are stretched under a heating zone thus forming a double cone. This
special waveguide structure allows control of the splitting ratio via controlling length of the fiber torsion
angle and stretch.
The fiber optic PLC splitter is a more new technology as it offer a better solution for larger applications.
Waveguides are fabricated using lithography onto a silica glass substrate, which allows for routing
specific percentages of light. As a result, PLC splitters offer accurate and even splits with minimal loss in
an efficient package. The PLC splitter is a micro-optical element using photolithographic techniques to
form optical waveguide at medium or semiconductor substrate for realizing branch distribution
function.
There are Balanced splitters that consists of 2 input fibers and N output fibers which divide the power of
the optical signal proportionally. They are mainly used for non-simultaneous redundancy.
Advantages of optic splitters include:

The FBT splitter offers low cost, common materials (quartz substrate, stainless steel, fiber, hot dorm,
GEL), and an adjustable splitting ratio.

PLC splitter: Losses are not sensitive to the wavelength, spectral uniformity is higher, it is more
compact and is lower cost with greater degrees of splitting.
