Fiber Optic Splitter

FIBER OPTIC SPLITTER

The usage of passive optical components like fiber optical splitters holds paramount importance in the field of fiber optical network technologies. These splitters are usually used for maximizing the performance of optical network circuits. A fiber optic splitter can split the incident light beam into two or more than two light beams and vice versa. That’s the reason it is also known as a beam splitter. It contains multiple input and output ends. Therefore, when the light transmitted on a network needs to be divided, a fiber optic splitter is implemented for the convenience of network interconnections.

How Does A Fiber Optic Splitter work?

The working principle of fiber optic splitters follows the principle of total internal reflection and generally follows the procedure described next. When a light signal is transmitted in any single-mode optic fiber, the light energy is not entirely concentrated in the fiber optic core. As a result, some amount of energy is spread through the covering of optic fiber. In simple words, if there are two optic fibers in close proximity to each other, the transmitting light in one optical fiber can enter the other optical fiber. That’s why the reallocation technique of optical signals can be achieved into multiple fibers, and that’s how a fiber optic splitter comes into play. It helps in confining the light to the core of fiber optic.

In how many types a fiber optic splitter can be classified?

Currently, there are only two types of fiber optic splitters– Planar Lightwave Circuit (PLC) Splitter and Fused Biconical Taper (FBT) Splitter.

PLC Splitter

A PLC Splitter is basically a passive optical device commonly used in Passive Optical Networks(PON) by connecting it to the Main Distribution Frame(MDF). FTTx and FTTH networks, including GPON, BPON, and EPON, all use PLC splitters in their design. So, how a PLC splitter generally works?

A Planar Lightwave Circuit Splitter divides the input signal into multiple output signals with an optic splitter chip. Usually, one optic splitter chip can achieve a maximum of 64 ends. PLC splitters are mainly used for larger applications. All the losses of the PLC splitter are insensitive to the wavelength, which greatly satisfies the requirement for multiple wavelength transmissions. Its configuration is compact and has a small size, saving a lot of installation space.

FBT Splitter

A Fiber Biconical Taper splitter is a type of conventional technology where two or more fibers are welded together with heat application. Basically, the optic fibers are stretched under the heat to form a double cone. As commonly available materials are used, thus an FBT splitter is a cost-effective option. However, the losses of an FBT splitter are sensitive to the wavelengths. Therefore, an FBT device must be chosen as per the wavelengths.

What are the advantages of Fiber Optic Splitter?

Here are a few advantages of using a fiber optic splitter:

• In a PLC splitter, the loss is insensitive to the wavelength of the transmitted light and will be able to meet the transmission needs of different wavelengths.
• The light signal is evenly split; thus, the signal can be evenly distributed to the end-users.
• It has a compact size and small volume; as a result, it can be directly installed at several existing transfer boxes. It does not even require any particular design, which further leaves a lot of installation space.
• A single device has many shunt channels that can reach more than 32 channels.
• The multi-channel cost is comparatively low and has a cost advantage.

Therefore,

Fiber Optic Splitters are a unique solution that can potentially improve the efficiency of optical infrastructures. Whether you choose a PLC splitter or an FBT splitter, go through the specifications of each product and your requirements. Selecting proper equipment is essential for optical networks, so go through our website and see which fiber optic splitter best serves your needs.

Can fiber optic cable be split?

Fiber optic cable can’t be split; after the optical fiber enters the home, connect the ONU and convert it into a network cable, and then connect to the router to split the signal.

How does a Fiber optic splitter work?

The optical fiber splitter is a device used to realize the splitting and combining of light wave energy. It distributes the light energy transmitted in one optical fiber to two or more optical fibers according to a predetermined ratio, or divides the optical energy into multiple optical fibers. The transmitted light energy is combined into a single fiber."

What is the difference between coupler and splitter?

The connection method of the coupler is like wrapping two small glass fibers at high temperature to fix them. The advantage is that the output power can be changed to each household, but the disadvantage is that the cost of the machine above 16 points is high.

The connection method of the fiber optic splitter is auto focus, and the number of split lines in the splitter is fixed, which enables high-precision docking. (You know the roots of the tree). The advantage is that the cost of the machine above 16 points is low, and the disadvantage is that the power can only be distributed evenly to each household.
