The Advantages And Disadvantages Of The PLC Optical Power Splitter

Planar optical waveguide technology is the optical waveguide branch devices with semiconductor process, the function of the shunt on the chip, to achieve the above shunt up to 1×32 on a chip, the chip at both ends, respectively, coupled to encapsulate the input and outputend multi-channel fiber array.

PLC fiber optic splitters are used to distribute or combine optical signals, which are based on planar lightwave circuit technology and provides a low cost light distribution solution with small form factor and high reliability.

The PLC fiber Splitter contains no electronics and uses no power. They are the network elements that put the passive in Passive Optical Network and are available in a variety of split ratios, including 1:4, 1:8, and 1:16, 1:32, 1:64 and 1:128 etc.

The main advantages:

(1) wear and tear on the transmission wavelength of light is not sensitive to meet the needs the transmission of different wavelengths.

(2) spectrophotometric uniform, the signal can be assigned to the user.

(3) The compact structure, small size, can be installed directly in a variety of transfer of the box, without specially designed to stay a great deal of installation space.

(4) single device shunt channel can reach more than 32.

(5) multi-channel, low cost, points more and more large ones, the more obvious cost advantage.

The main drawback:

(1) complex device fabrication process, high technical threshold, the current chip monopolized by several foreign companies, domestic enterprises to be able to the production of large quantities of packaging and only a small few.

(2) relative to the higher cost of fused cone splitter, especially in the low-channel splitter at a disadvantage.

The method to Install Fiber Optic Connectors

Fiber optic cables have been instrumental in advancing technological communication. Fiber optics today stretch across oceans and bring Internet connection to remote locations. They provide more reliable service for land-line phones than traditional wires. Although their manufacture can be complex, you can install fiber optic connections very easily. The process involves gluing bare fiber optic cable to a connector and then heating the connector to seal it.

1. Strip the plastic jacket at the end of the fiber optic cable. Optic cable ends have jackets to prevent any damage in shipping from the manufacturer. Clamp the plastic jacket, using a fiber optic stripper tool, which has a designated slot to fit the size of a fiber optic jacket. Squeeze the handles of the stripper like pliers. Pull the jacket away from the fiber optic cable.
2. Open the back chamber of the epoxy glue gun by twisting off the back cap. Insert the epoxy glue tube into the chamber and squeeze lightly. You will only need a few ounces of glue for the task. Screw the cap back on the epoxy glue gun chamber.
3. Inject epoxy glue into the fiber optic connector socket. Each fiber optic connector has two sockets on each side of it to form the connection. Insert the glue gun into the connector socket. Press and hold the trigger to insert the glue. The glue should spot should not be larger than an eye pupil.
4. Insert one fiber optic cable end into the connector sockets. Hold the cable in the socket and count to 10. Let go of the fiber optic cable and connector. Check that the cable stays in position once you let go of it.
5. Place the new fiber optic connection into an an epoxy curing oven. Turn on the oven and turn the timer knob to six minutes. Insert the fiber optic connector attached to the cable into one of the curing oven slots. Press the start button on the oven. Pull out the connector from the oven slot. Wiggle the connector end to test the stability of the connection. If it seems fragile, reinsert the connector into the oven and cook it for a few more minutes. Repeat steps three to five to seal the fiber optic connector on both sides.

Fiber Optic Cable Repairing Method

Fiber optics can repaired by several methods. Splicing allows two fiber optic cables to be joined together. Splicing enables the joining of broken cables or two different types of cables, The process is done with fusion splicing or mechanical splicing.

Fusion Splicing

Fusion splicing joins two cable optic lengths together with electric arc welding. Fusion splices generally cost from $0.50 to $1.50 each (as of 2011). However the splicing machine costs from $15,000 to $50,000 depending upon the level of accuracy required.
Mechanical Splicing

Mechanical splicing is done with a device that fits between two cables being spliced and aligns the fiber ends. Mechanical splices cost between $12 and $50 each. However, the initial investment is $1,000 to $2,000. The choice of the method can be based upon precision. Fusion splicing provides lower feedback reflection and less loss of signal. Some companies use each method depending upon whether precision digital signals are being sent or less precise analog signals.

Patch Cable

In most cases, there will not be sufficient slack in a broken cable to allow splicing without additional cable. After determining that a patch cable will work in the system, a temporary length of cable can be mechanically spliced and laid on the ground if temperatures do not fall below freezing. Outdoor repairs should be done in a temporary shelter, such as a tent, if possible, to protect the work from the elements.

What Is the Difference Between Ethernet & Patch Cables?

Ethernet Is a Protocol

While eight-conductor Ethernet cables with RJ-45 plugs are extremely common (these are the cables that look like over-sized phone cords), Ethernet itself is a protocol standard that defines the way that bits of information travel over a particular medium. The two most common cabled versions of Ethernet are traditional copper cables and fiber-optic cables.

Patch Cables

Most standard copper Ethernet cables are referred to as patch cables. However, ordinary phone cords can be considered patch cables, as well as the RCA and HDMI cables that connect a home TV and stereo system together.


Different Ethernet cables have different names, with “patch cables” being the most common. Some of the differences include the length of the cable as well as the purpose. For example, an Ethernet connection that is designed for speed and/or great distance can be referred to as a “backbone” or “long haul,” even though it may use the exact same type of copper cable that a patch cable uses.
